you start running at a speed of 2.65 m/s. it takes you 13.5 s to catch up and deliver the lost wallet. The person in front was 28.35 meters ahead of you when you started running to catch up and return their wallet.

When walking at a speed of 1.25 m/s, the distance between the two people remains the same, so we can assume that the person in front was also walking at the same speed of 1.25 m/s. When you start running at a speed of 2.65 m/s, you cover the same distance in a shorter amount of time, allowing you to catch up to the person in front. To calculate the distance between you and the person in front before you started running, we can use the formula:
distance = speed x time
When walking, the distance between you and the person in front remains constant, so we can calculate the distance using:
distance = speed x time
distance = 1.25 m/s x t
When running, you cover the same distance in a shorter amount of time, so we can calculate the distance using:
distance = speed x time
distance = 2.65 m/s x 13.5 s
Since the distance is the same in both cases, we can set them equal to each other and solve for t:
1.25 m/s x t = 2.65 m/s x 13.5 s
t = (2.65 m/s x 13.5 s) / 1.25 m/s
t = 22.68 s
Therefore, the person in front was walking for 22.68 seconds before you started running. To calculate the distance, we can plug in the value of t into the first equation:
distance = 1.25 m/s x t
distance = 1.25 m/s x 22.68 s
distance = 28.35 meters
Therefore, the person in front was 28.35 meters ahead of you when you started running to catch up and return their wallet.

Frequency is perceived by humans as pitch; The sound intensity is the amplitude; Humans can only hear a specific range of sound, usually from 20 Hz to 20,000 Hz; The factors that go into a sound are its intensity, frequency and overtones (which are like interference, or background noises).

It's "Pitch" on edge.

Answer:37

Explanation:

Answer:

When one system vibrating at its natural frequency is put closer to a stationary system, the stationary system receives impulses.

At resonant frequency, the system vibrating at its own natural frequency suddenly goes on decreasing in order to cope with neighboring system.

These decrease in frequency is known as damping.

Answer:

0.16 rad /s

Explanation:

Given that :

Time, t = 9.46 s

Quarter turn = 1/4 rev

θ = wt

w = angular speed `. ; t = time in second

1 rev = 2 pi

θ = 2pi

1/4 θ = 1/4 * 2pi = pi/2

θ = wt

pi/2 = w * 9.62

3.14 = w * 9.62 * 2

3.14 = 19.24w

w = 3.14 / 19.24

w = 0.1602040

If the chemical makeup of a combination remains constant throughout, it is considered to be homogenous. Homogeneous mixtures and pure substances are sometimes confused with one another since they are both uniforms. The uniformity of the substance's makeup matters. The amount of salt in the water can vary from sample to sample.

All solutions would be regarded as homogenous since the dissolved ingredient is distributed uniformly across the entire solution. Since none of the components of the combination have interacted with one another, the identities of the individual materials have not changed.

Explanation:

i’m not sure if that’s right but that’s what i think

C. A heat pump absorbs 100 J of heat from a cool reservoir and releases 120 J of heat to a hot reservoir.

In order to operate, a heat engine must reject some of the heat it receives from the high-temperature source to a low-temperature sink.

A heat engine that violates the second law converts 100 percent of this heat to work. This is physically impossible. This heat engine violates the second law of thermodynamics.

The second law can also be stated as no heat engine can have a thermal efficiency of 100 percent.

The thermal efficiency of a heat engine is defined as the ratio of the work output to the heat input:

Clearly, if the thermal efficiency of a heat engine is 100 percent,

Qin=Wout

If the second law precludes a heat engine from having a thermal efficiency of 100 percent. A heat engine is a device that converts a portion of the heat supplied to it from a high-temperature source into work. The remaining heat is rejected to a low-temperature sink.

Therefore:

A heat pump absorbs 100 J of heat from a cool reservoir and releases 120 J of heat to a hot reservoir.

Both magnetic force and gravitational force are fundamental forces that operate at a distance. Both forces obey an inverse square law in terms of distance, which means that the force becomes weaker as the distance between the two objects increases.

Magnetic force and gravitational force are two distinct forces, however, they do have a common similarity. They are both basic forces that operate at a distance. Both forces obey an inverse square law in terms of distance, which means that the force becomes weaker as the distance between the two objects increases.

Magnetic force is generated by the motion of electric charges, while gravitational force is generated by the mass of an object. The interaction between two objects is given by the product of their masses and the inverse square of the distance between them in the case of gravitational force.

The interaction between two magnetic objects, on the other hand, is determined by the distance between them, the magnitude of their magnetic field, and their magnetic moment, which is a measure of the strength of the magnetic field.

The force between two magnetic objects is proportional to the product of their magnetic moments and the inverse square of the distance between them. Because both magnetic force and gravitational force obey an inverse square law, they both result in an attractive force between two objects. The strength of the force varies as the distance between the objects changes.

In conclusion, the similarity between magnetic force and gravitational force is that they are both fundamental forces that operate at a distance and obey an inverse square law in terms of distance.

Answer: RIGHT angles

Explanation:

The pressure of gas produces a net force, i.e., the sum of all the forces at right angles to the wall of a container.

A key idea in physics is pressure, which is measured as the amount of force per unit area acting perpendicular to a surface.

Imagine holding a tack between your forefinger and thumb, with the head on your forefinger and the pointy end on your thumb, and lightly pressing it there to comprehend pressure. The forefinger will not experience discomfort, but the thumb will feel it right away. The thumb is under the same amount of pressure as the forefinger due to the tack's limited surface area, but the pressure on the thumb is significantly greater.

A net force pressing on the container walls is created as a result of collisions with the container. Gas pressure is a result of this force acting perpendicular to the container walls. A pressure gauge can be used to measure this pressure.

Answer:

v₂ = 1.8 [m/s]

Explanation:

To be able to solve this problem we must raise the principle of conservation and quantity of movement. It is going to study the momentum before and after the firing of the rifle.

P = m*v

where:

P = momentum [kg*m/s]

m = mass [kg]

v = velocity [m/s]

Now we need to analyze the moment before and after the shot.

\((m_{1}+m_{2})*v_{1}=-(m_{1}*v_{2})+(m_{2}*v_{3})\)

where:

m₁ = mass of the rifle = 5 [kg]

v₁ = velocity of the rifle and the bullet before firing = 0 (no movement)

m₂ = mass of the bullet = 15 [g] = 0.015 [kg]

v₂ = velocity of recoil [m/s]

v₃ = velocity of the bullet after firing = 600 [m/s]

Now replacing:

\((5+0.015)*0 = -(5*v_{2})+(0.015*600)\\9 = (5*v_{2})\\v_{2}=1.8 [m/s]\)

Momentum is the product of mass and velocity. The recoil velocity of the rifle weighing 5 kg is 1.8 m/s.

According to the law of conservation of momentum if two objects are in contact with each other then for that system of the two objects the momentum of the object before will be equal to the momentum of the object after the collision.

GIven to us

Mass of the rifle, M = 5 kg

Mass of the bullet, m = 15 g = 0.015 kg

Velocity of the bullet afterwards, v₂ = 600 m/s

We know that according to the law of conservation of momentum, the momentum of the bullet and riffle before shooting will be equal to the momentum of the bullet and riffle after shooting.

\(Mu_1 + mu_1 = Mv_1 + mv_2\)

Since, before shooting the bullet was in the riffle and the velocity of both was 0,

\(M(0) + m(0) = Mv_1 + mv_2\\\\-Mv_1 = mv_2\\\\v_1 = -\dfrac{m \times v_2}{M}\)

Substitute the values,

\(v_1 = -\dfrac{0.015 \times 600}{5}\\\\v_1 = -1.8\rm\ m/s\)

Thus, the recoil of the rifle is -1.8 m/s, the negative sign denotes that the velocity of recoil was in opposite direction to the bullet.

Hence, the recoil velocity of the rifle weighing 5 kg is 1.8 m/s.
