I WILL GIVE U BRAINLIEST PLSS HELP You have two balloons. You rub each balloon on your hair and your friends hair. You and your friends hair then sticks to the balloon because of static electricity. The balloon is positively charged and your hair is negatively charged so they attract. What would happen if you tried to put the balloons together?

Answers

Answer 1

Answer: The balloon is charged by rubbing it on your hair. When you put it near a neutral object (paper, Styrofoam or puffed rice cereal), the electrons in the object repel away from the balloon and the protons are attracted to the balloon. This movement of the electrons causes the neutral object to get a low positive charge.

what reasons can u give for the difference in speed for each cars?

Answers

Answer:

There are many factors that can affect the speed of a car, including:

Engine size and power: A car with a larger and more powerful engine will be able to accelerate faster and reach higher speeds than a car with a smaller engine.

Transmission: Cars with manual transmissions typically have better acceleration than those with automatic transmissions because the driver can control the gears and timing of the shift.

Aerodynamics: Cars that are designed with aerodynamic shapes and features, such as a low profile or smooth body, will be able to reach higher speeds and maintain them more easily than cars with less aerodynamic designs.

Weight: Cars that are lighter in weight will be able to accelerate faster and reach higher speeds than cars that are heavier.

Tires: Cars with wider tires will typically have more grip and better traction, which can allow them to reach higher speeds and handle better.

Suspension: Cars with better suspension systems will be able to maintain stability at high speeds and handle better.

Driving technique: The way a driver handles a car can also affect its speed, a skilled driver can make the most of the car's performance and get a better outcome.

Answer:

distance and time

Explanation:

Speed depends upon distance and time. So, if the distance is long but time is less, the speed will be high. On the other hand, if the distance is short and time is enough, the speed of the car will be slow.

A skydiver dives from an airplane. Air resistance is measured each second following the skydiver’s jump. Which statement BEST identifies the skydiver’s speed at each second?
PLS HELP QUICK

Answers

Answer: (B) 4 Seconds

Explanation: The Balance of weight and air resistance equals out after 4 seconds giving you your terminal velocity. (the fastest speed you can travel at your given weight and air resistance)

Answer : B. The sjydriver has the fastest speed at 4second.

What is air resistances ?

--Air resistance is a type of friction force.

-- Air resistance, there are not two solid surfaces in contact.

-- Air resistance is the frictional force acting on an object and the air around them.

--This means that friction always pushes in the opposite direction than the skydiver is travelling, therefore slowing the skydiver down.

Concept Used

-- When the skydiver jumps off the plane, their speed would accelerate because the pull of gravity on the person, or their weight force, is greater than the air resistance slowing them down.

-- A person’s weight force will always stay the same.

-- The weight force of the person will equal their air resistance.

-- This would make the skydiver travel at constant speed.

--To travel at constant speed forces have to be equal to zero.

--This constant speed is called terminal velocity

An object is held 24.8 cm from a lens of focal length 16.0 cm. What is the magnification of the image?

Answers

Answer:

Magnification is 1.8

Explanation:

Given data

object distance u = 24.8 cm

focal length f= 16 cm

image distance v= ?

In other to solve for the magnification we have to solve for the image distance

The mirror formula is

$\frac{1}{v} +\frac{1}{u}= \frac{1}{f} \\$

Substituting we have

$\frac{1}{v} +\frac{1}{24.8}= \frac{1}{16} \\\\\frac{1}{v}= \frac{1}{16} -\frac{1}{24.8}\\\\\frac{1}{v}=\frac{24.8-16}{396.8}= \frac{8.8}{396.8}= \frac{1}{45}\\\\v= 45cm$

The magnification is

$m= \frac{v}{u}\\\m= \frac{45}{24.8}\\\\m= 1.8$

A driver is driving a 6371 kg lorry. After spotting a hazard, the driver applies the brakes. The lorry decelerates uniformly and comes to a stop 60 m after the brakes are applied. Estimate the braking force needed to stop the lorry.

Answers

Answer:

The estimated braking force needed to stop the lorry is zero, based on the given information and calculations. However, it's important to note that this result is likely not accurate, as some force is required to stop a moving object. It's possible that additional information or calculations are needed to obtain a more realistic estimate of the braking force.

Explanation:

To estimate the braking force needed to stop the lorry, we can use Newton's second law of motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a).

In this case, the lorry decelerates uniformly, so the acceleration is constant. The initial velocity is assumed to be zero since the lorry comes to a stop. The final velocity is also zero. Therefore, we can use the equation:

Final velocity squared (vf^2) = Initial velocity squared (vi^2) + 2 * acceleration (a) * distance (d)

Since vi = 0 and vf = 0, the equation simplifies to:

0 = 0 + 2 * a * d

Solving for acceleration (a), we have:

2 * a * d = 0

a = 0

Since the acceleration is zero, it means that the braking force needed to stop the lorry is also zero. This is likely not an accurate result as some force is required to stop the lorry. It's possible that additional information or calculations are needed to accurately estimate the braking force.

The braking force required to stop a 6371 kg lorry after spotting a hazard and applying the brakes is what the question is asking for. The lorry decelerates uniformly and comes to a stop 60 meters after the brakes are applied.

The following steps will guide you on how to calculate the braking force:

Step 1: Determine the mass of the lorry which is 6371 kg. This will be denoted as m.

Step 2: Determine the distance travelled by the lorry, which is 60 m.

Step 3: Determine the time taken by the lorry to stop. This can be done by using the formula for uniform deceleration, which is a = (v-u)/t where v is the final velocity, u is the initial velocity and a is the uniform deceleration. Since the lorry comes to a stop, its final velocity is zero and its initial velocity is unknown.

However, we can assume that the lorry was initially travelling at a constant speed before spotting the hazard. Therefore, we can assume that the initial velocity was equal to the average velocity of the lorry before the brakes were applied.

This can be calculated using the formula v = d/t where d is the distance travelled and t is the time taken. The average velocity can therefore be calculated as follows: v = d/t = 60 m/t

Step 4: Rearrange the formula for uniform deceleration, a = (v-u)/t, to find u which is the initial velocity. Since the lorry comes to a stop, we know that v = 0.

Therefore: u = v - at where a is the uniform deceleration and t is the time taken to stop which is also equal to the time taken for the lorry to travel the distance of 60 meters. Substituting for v, we get: u = - at

Step 5: Calculate the acceleration of the lorry using the formula a = (v-u)/t. Since the final velocity is zero, we get: a = -u/t = -(-at)/t = a The acceleration is negative since the lorry is decelerating.

Step 6: Calculate the braking force using the formula F = ma where F is the braking force and m is the mass of the lorry. Therefore: F = ma = (-ma) since a is negative = (-6371 kg) (a) Therefore, the braking force required to stop the lorry is -6371a N where a is the uniform deceleration calculated in Step 5.

How does the sport curling relate to Newton’s Second Law of Motion?

Answers

Curling is a sport in which players slide stones across a distance of ice toward a target area. The purpose is to accumulate the loftiest score for a game by making monuments rest closest to the center of the target at the end of each side. There are two brigades. Each platoon is trying to keep the other platoon's monuments down from the target by knocking their monuments out of the way.

Newton's Second Law " The acceleration of an object is directly commensurable to the net force acting on it and is equally commensurable to its mass. The direction of the acceleration is in the same direction as the net force acting on an object." This relates to the formula F = ma. The mass of the determinedness monuments in curling is 38 to 44 pounds or 17.3 to 20 kg. The thing of the sweepers is to control the acceleration of the gravestone by reducing disunion on the ice, which affects the force with which the gravestone is suitable to impact the other monuments.

In the sport of curling, the stone slides down the lane on the ice after being thrown by the deliverer as speeds change. Without newtons first law being applied the stone would either be at rest or moving at a constant velocity, but the force of friction and gravity on the stone eventually bring the stone to a stop. This is what the sweepers are used for, as they clean the ice and pave a way for the stone to move faster and farther based on their strategies.

Second law-
Newtons second law occurs during curling when the delivery man, such as Glenn Howard, applies force to the stone pushing down the lane to the target while friction pulls it back the other way to a slow stop. The mass of the stone is 40lbs and the net force of everything on item will give you its slowly decreasing acceleration. Otherwise known as, F=mA.

Third law-
This law can be exerted in the sport of curling when the force behind a stone being delivered is transferred into another stone that is at rest, where the energy and force of one moving object is transferred to another. This almost completely stops the original stone, and gives some speed to the stone(s) it collides with.

This is called its terminal velocity. Objects with a large surface area such as parachutes or sheets of paper reach terminal velocity much more quickly than objects with a small surface area because air resistance will have that much of a greater impact.

The velocity of the vehicle is equal to 406.5 m/s. The velocity in Km/hr is 1463.4 Km/hr.

What is the velocity?

Velocity can be demonstrated as a vector measurement of the direction of the object and the rate of motion of an object. The velocity of an object can be described as the change in the body's position w.r.t. time.

Velocity can be expressed as a vector quantity as it consists of magnitude as well as direction. A mathematical formula common and simplest way to find velocity.

v = d / t

Where v is the velocity, d is the distance covered and t is the time taken by the body.

The S.I. unit for velocity can be represented as m/s and can be expressed in terms of miles per hour (mph), and kilometers per hour (kph).

Given, the distance traveled by the vehicle, d = 100 m

The time taken by vehicle = 0.246 sec

The velocity of the vehicle, v = 100/0.246 = 406.5 m/s

We know that 1km = 1000m then 1 m = 10⁻³ Km

1 hour = 60 ×60 = 3600 s

1s = 1/3600 hr

Therefore, velocity, $\displaystyle v = 406.5 \times \frac{3600}{1000} Km/hr$

v = 1463.4 Km/hr

brainly.com/question/19979064

#SPJ2

The velocity of the vehicle can be calculated by dividing the distance traveled by the time taken:

Velocity = Distance / Time = 100 m / 0.246 s = 406.50 m/s

To convert m/s to km/hr, we need to multiply the velocity by 3.6:

Velocity in km/hr = Velocity in m/s x 3.6 = 406.50 m/s x 3.6 = 1463.80 km/hr

The steps I took to convert from m/s to km/hr were to multiply the velocity in m/s by 3.6, which is the conversion factor between meters per second and kilometers per hour.
