a 5.0- kgkg rabbit and a 12- kgkg irish setter have the same kinetic energy. if the setter is running at speed 1.3 m/sm/s , how fast is the rabbit running?
The rabbit is running at approximately 1.77 m/s.
The kinetic energy of an object can be calculated using the formula:
KE = (1/2) * m * \(v^{2}\)
Where:
KE is the kinetic energy,
m is the mass of the object, and
v is the velocity of the object.
In this case, the kinetic energy of the rabbit and the Irish Setter is the same. Let's denote the velocity of the rabbit as vr and the velocity of the Irish Setter as vs.
We are given:
Mass of the rabbit (mr) = 5.0 kg
Mass of the Irish Setter (ms) = 12 kg
Velocity of the Irish Setter (vs) = 1.3 m/s
Since the kinetic energy is the same for both, we can set up the equation:
\((1/2) * m_r * v_r^2 = (1/2) * m_s * v_s^2\)
Plugging in the given values:
\((1/2) * 5.0 kg * v_r^2 = (1/2) * 12 kg * (1.3 m/s)^2\)
Simplifying the equation:
2.5 * \(vr^2\) = 7.8
Dividing both sides by 2.5:
\(vr^2\) = 7.8 / 2.5
\(vr^2\) = 3.12
Taking the square root of both sides:
vr = √3.12
vr ≈ 1.77 m/s
Therefore, the rabbit is running at approximately 1.77 m/s.

4. The kinetic energy of a boat is calculated at 52,000 J. If the boat has a mass of 39,000
kg, with what velocity is it moving?
Answer:
The kinetic energy (KE) of an object is given by the formula:
KE = (1/2)mv^2
where m is the mass of the object and v is its velocity.
Given that the boat has a kinetic energy of 52,000 J and a mass of 39,000 kg, we can rearrange the formula to solve for v:
v = sqrt(2KE/m)
Substituting the values, we get:
v = sqrt[(2 x 52000 J) / 39000 kg]
v = sqrt(104000 J / 39000 kg)
v = sqrt(2.6667 J/kg)
v = 1.632 m/s
Therefore, the boat is moving with a velocity of approximately 1.632 m/s.

Larissa volunteers to pick up litter on the weekends to help clean up the environment in her community. one day, at the lake, she finds an empty soda bottle floating on the surface. then, she finds a full soda bottle that has sunk to the bottom near her feet. upon examining the bottles, she finds that they are the exact same brand and size. why did one bottle float while the other one sank?(1 point)
The reason one soda bottle floated while the other one sank is due to the difference in their densities. Density is the mass of an object divided by its volume.
Density is an important physical property and plays a significant role in various scientific disciplines, such as physics, chemistry, geology, and engineering. It helps identify and differentiate substances, determine their behavior under various conditions, and provides insights into the composition and structure of materials. For example, denser materials sink in water, while less dense materials float, making density a key factor in understanding buoyancy.
In this case, the full soda bottle that sank had a higher density than the empty soda bottle that floated. The density of an object determines whether it floats or sinks in a liquid. Objects with a density greater than the liquid they are placed in will sink, while objects with a density less than the liquid will float.

Which type of extinguisher is intended to be used on a Class B fire?
Select one:
- Pump-type water extinguisher
- Stored-pressure water-mist extinguisher
- Stored-pressure wet chemical extinguisher
- Aqueous film forming foam extinguisher
The type of extinguisher that is intended to be used on a Class B fire is the Aqueous film forming foam (AFFF) extinguisher. The AFFF extinguisher is the main answer to the question.
An Aqueous film forming foam extinguisher is designed to extinguish fires that are fueled by flammable liquids like oil, gasoline, or kerosene. This extinguisher works by covering the fuel source with a layer of foam that deprives the flames of oxygen. The foam also helps to cool the fuel, further limiting the spread of the fire.
There are different types of fires, and each requires a specific type of extinguisher. A Class B fire is fueled by flammable liquids, including gasoline, oil, and kerosene, among others. These fires can be extremely dangerous and difficult to extinguish, which is why it's important to use the right type of fire extinguisher.
The Aqueous film forming foam extinguisher (AFFF) is the most effective type of extinguisher for Class B fires. This type of extinguisher works by smothering the flames with a layer of foam that contains water and a special chemical agent. The foam creates a barrier that cuts off the fire's oxygen supply and prevents it from spreading. AFFF extinguishers are stored-pressure extinguishers, which means that the foam is already mixed with water and ready to use.
In conclusion, the Aqueous film forming foam extinguisher (AFFF) is the type of extinguisher intended to be used on a Class B fire. This type of extinguisher is highly effective in smothering flames and preventing the fire from spreading. It is essential to use the right type of extinguisher for the type of fire to prevent the fire from growing.

For a normal distribution with mu = 100 and sigma = 10, what percentage of scores have values less than X = 85?
In a negatively skewed distribution of scores, what is the probability of sampling a z-score less than 1.00?
For a normal distribution with mu = 100 and sigma = 10, we can use the standard normal distribution table to find the percentage of scores that have values less than X = 85.
First, we need to standardize the value of X using the formula: z = (X - mu) / sigma. Plugging in the given values, we get: z = (85 - 100) / 10 = -1.5. Using the standard normal distribution table, we can find the percentage of scores that have z-values less than -1.5. The table gives us the area under the standard normal distribution curve to the left of a given z-value. Since the distribution is symmetric, we can look up the area to the right of -1.5 and then subtract it from 1 to get the area to the left of -1.5. Looking up the area to the right of -1.5 in the standard normal distribution table, we find that it is 0.0668. Therefore, the area to the left of -1.5 is: 1 - 0.0668 = 0.9332. This means that approximately 93.32% of scores have values less than X = 85 in a normal distribution with mu = 100 and sigma = 10. In a negatively skewed distribution of scores, the mean is less than the median, and the tail of the distribution is longer on the left side. If we sample from this distribution, the probability of sampling a z-score less than 1.00 will depend on the specific parameters of the distribution. However, we can make some general observations about the probability of sampling a z-score less than 1.00. Since the distribution is negatively skewed, we know that there are fewer scores on the left side of the distribution than on the right side. This means that the probability of sampling a z-score less than 1.00 will be less than 0.50. To get a more precise answer, we would need to know the specific parameters of the distribution. If we know the mean and standard deviation of the distribution, we can standardize the value of 1.00 using the formula: z = (x - mu) / sigma, where x is the value of interest, mu is the mean of the distribution, and sigma is the standard deviation of the distribution. We can then use the standard normal distribution table to find the probability of sampling a z-score less than the standardized value.

you are designing a diving bell to withstand the pressure of seawater at a depth of 210 m. part a what is the gauge pressure at this depth? (you can ignore changes in the density of the water with depth.)
The gauge pressure at the depth of 210 m will be 2.11974 x 10^{6} Pa .
What is gauge pressure ?
The amount of pressure measured in relation to the applied atmospheric pressure is known as gauge pressure. A diaphragm sensor can be used to measure gauge pressure, with one side of the diaphragm exposed to the pressure medium that has to be measured and the other exposed to the surrounding atmospheric pressure.
The pressure from the weight of the atmosphere is included in gauge pressure readings because gauge pressure is zero-referenced against ambient air (or atmospheric) pressure. This indicates that gauge pressure varies in response to both weather and height above sea level. Gauge pressure measurement is adequate for the majority of industrial applications because every operation in a refinery or manufacturing facility operates at the same air pressure.
The gauge pressure is ;
P = density x g x depth
where , density is of sea water .
Calculate the gauge pressure as -:
P = density x g x depth
= (1030 kg/m^{3})(9.8 m/s^{2})(210 m)
= 2.11974 x 10^{6} Pa .

a building under construction requires building materials to be raised to the upper floors by cranes or elevators. an amount of cement is lifted 56.4 m by a crane, which exerts a force on the cement that is slightly larger than the weight of the cement. if the net work done on the cement is 987 j, what is the magnitude of the net force exerted on the cement?
To determine the magnitude of the net force exerted on the cement lifted by the crane, we are given the height it is raised, the net work done on the cement, and the information that the force exerted is slightly larger than the weight of the cement. Using the work-energy principle, we can calculate the net force by dividing the net work done by the distance lifted.
According to the work-energy principle, the net work done on an object is equal to the change in its kinetic energy. In this case, the net work done on the cement is given as 987 J. Since the crane exerts a force slightly larger than the weight of the cement, it means that the net force and the displacement have the same direction.
Using the formula for work, W = Fd, where W is the work done, F is the force, and d is the distance, we can rearrange the formula to solve for the force F: F = W / d.
Substituting the values, with the net work done on the cement as 987 J and the distance lifted as 56.4 m, we can calculate the magnitude of the net force exerted on the cement by dividing the net work done by the distance lifted.

Assuming the cross-sectional area of the Earth to be about 1.28×10^18 cm2, what is the total annual amount of incoming energy? Express your answer using three signifioant figures.
Expressing the answer using three significant figures, the total annual amount of incoming energy on Earth is approximately 1.74×10¹⁹ Watts.
To calculate the total annual amount of incoming energy on Earth, it is required to consider the solar constant, which represents the amount of solar energy received per unit area outside the Earth's atmosphere. The solar constant is approximately 1361 Watts per square meter (W/m²).
First, it is required to convert the Earth's cross-sectional area from cm² to m².
1.28×10¹⁸ cm² = 1.28×10¹⁶ m²
Total annual incoming energy = Solar constant × Earth's cross-sectional area
Total annual incoming energy = 1361 W/m² × 1.28×10¹⁶ m²

In the process of loading a ship, a shipping container gets dropped into the water and sinks to the bottom of the harbor. Salvage experts plan to recover the container by attaching a spherical balloon to the container and inflating it with air pumped down from the surface. The dimensions of the container are 5.80 m long, 2.60 m wide, and 2.80 m high. As the crew pumps air into the balloon, its spherical shape increases and when the radius is 1.50 m, the shipping container just begins to rise toward the surface. Determine the mass of the container. You may ignore the weight of the balloon and the air in the balloon. The density of seawater is 1027 kg/m3.
Answer:
57.885.8 kg weight of the container
Explanation:
The volume of the balloon * density of water = buoyant force of balloon
volume of a sphere = 4/3 pi r^3
= 4/3 pi * (1.5)^3 = 14.14 m^3 <===balloon volume
Now, find the buoyant force on the container ALONE ....
5.8 * 2.6 * 2.8 * 1027 = 43 364 kg <===== buoyant force
Now add the buoyant force of the balloon to find the weight
43 364 + 14.14 * 1027 = 57885.8 kg
A baseball is pitched at 70 miles per hour (but instead use 31.29 meters/second). The baseball has a mass of 0.145 kg. The catcher catches the ball, and the catcher has 95.9 kg of mass. The catcher is originally stationary (not moving). What is the speed of the catcher (and the ball, combined) immediately after he catches the baseball?
The combined speed of the catcher and the ball is 0.047 m/s.
What is the combined speed?In the case of the question that we have here, we would need to apply the principle of the conservation of linear momentum. It is the principle that stresses the fact that the momentum before collision must be the same as the magnitude of the momentum after collision.
We then have that;
Momentum before collision = Momentum after collision
(0.145 * 31.29) + (95.9 * 0) = (95.9 + 0.145)v

a truck is moving with a certain uniform velocity. it is accelerated uniformly by 0.75 m/s^2.after 20 seconds, the velocity becomes 72 km/h. find the initial velocity
Answer:
\(\boxed{V_{i} = 5\ m/s}\)
Explanation:
Given:
Acceleration = a = 0.75 m/s²
Time = t = ?
Final Velocity = \(V_{f}\) = 72 km/hr = 20 m/s
Required:
Initial Velocity = \(V_{i}\) = ?
Formula:
a = \(\frac{V_{f}-V_{i}}{t}\)
Solution:
For \(V_{i}\) the formula becomes:
\(V_{i} = V_{f}-at\)
\(V_{i}\) = 20 - (0.75)(20)
\(V_{i}\) = 20 - 15
\(V_{i}\) = 5 m/s
In Case: If you want it in km/hr:
\(V_{i}\) = 5 * 3.6
\(V_{i}\) = 18 km/hr
Answer:
5 m/s
Explanation:
acceleration = 0.75 m/s²
time = 20 s
final velocity = 72 km/h = 20 m/s
initial velocity = ?
Apply formula for initial velocity.
\(u=-at+v\)
\(\sf a=acceleration\\t=time\\v=final \: velocity\\u=initial \: velocity\)
Solve for u.
\(u=-(0.75)(20)+ 20\)
