Suppose that the ball in the last question is dropped from the same height as before, but this time it is attached to a light parachute. Compare the kinetic energy just before the ball hits the floor to your previous answer.

1. The kinetic energy just before the ball hits the floor is (the same/larger/smaller) .
2. In this case, mechanical energy (is/is not) conserved.

10 is the . . .

The answer is water molecules are split.cellular respiration and photosynthesis are complement  reactions to each other. these are reverse reactions. in cellular respiration glucose and oxygen yield water and carbon dioxide. so, when respiration begins,  glucose molecules are split. in the opposite reaction - in photosynthesis, carbon dioxide and water yield glucose and oxygen. thus,  when respiration begins, water molecules are split.

the speed of the cart after 3 seconds of low fan speed is ⇒ 54.0 cm/s.

the speed of the cart after 5 seconds of medium fan speed is ⇒ 120.0 cm/s.

the speed of the cart after 2 seconds of high fan speed is ⇒ 64.0 cm/s.
