A perfect bouncy ball would continue bouncing the same height forever. But in reality, the ball stops bouncing because energy is "lost" to ... A. sound energy
B. compression of the ball
C. heat energy absorbed by the ball
D. all answers are true

thermal energy is the answer

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

1) estimating temperature to the nearest tenth of a degree

2) estimating the mass of the sample to the nearest tenth of a gram

4) the position of the cups of sand and water under the heat lamp
