A toy car moves around a circular track at constant speed. It suddenly doubles its speed - a change of a factor of 2. As a result, the centripetal acceleration changes by a factor of a. No change since the radius doesn't change. b. 1/4. c. 2. d. 1/2. e. 0 4.

Scissors and a seesaw both cut things that’s the only comparison

The particles of the gas inside the ball heats up, bouncing off each other and spreading farther apart.hope my answer has you : )

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j
