Answer:
cause we hear differently
Explanation:
The correct answer is
<span>c the friction force from the road
In fact, the friction force between the road and the tires prevents the car from "sliding away" in a straight line and keeps it in circular motion, acting as centripetal force.</span>
Force is equal to weight, F= ma acceleration "a", is now due to gravity g = 9.8 m/s²
Given: Mass m = 1,000 Kg
F =ma W = mg = (1,000 Kg)(9.8 m/s²)
F = 9,800 N
Answer:
b)
Explanation:
Rotational inertia of the sphere: 
Rotational inertia of hollow sphere: 
Rotational inertia of flat disk: 
The largest value is 2/3 mr², therefore, hollow sphere's inertia is largest.
