Answer:
I believe that its B my apologies if its wrong/
Explanation:
The force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.
<h3>What is force?</h3>
Force is defined as the product of mass and acceleration of an object.
Friction is defined as the force that resists the movement of an object over another.
Therefore, the force exerted on the tires of a car that directly accelerate it along a road is exerted by the road friction.

As the satellite panels extend, the angular velocity decreases due to drag force, and hence it will cause a decrease in the angular momentum of the satellite.
<h3>
What is angular momentum?</h3>
Angular momentum is defined as the quantity of rotation of a body, which is the product of mass, velocity and radius.
L = mvr
L = mωr²
where;
- m is mass of the object
- v is velocity
- r is radius
- ω is angular velocity
As the satellite panels extend, the angular velocity decreases due to drag force, and hence it will cause a decrease in the angular momentum of the satellite.

I believe that it is the first one just a guess tho. So don't trust me, just in case
Answer:
<h2>470.59 kg</h2>
Explanation:
The the mass of the car can be found by using the formula

f is the force
a is the acceleration
From the question we have

We have the final answer as
<h3>470.59 kg</h3>
Hope this helps you
