From the time the ball leaves your hand until it hits the ground, the only force acting on it is gravity, and its acceleration is 9.8 m/s^2 downward ... the acceleration of gravity. It doesn't change. By the way, this statement applies whether you throw it or just drop it, and no matter which direction you decide to throw it.
<span>10. what part of the experiment was food? C. CONSTANT
11. What part of experiment was the heartbeat? B. DEPENDENT VARIABLE
12. what part of experiment was the h2o temp.? C. CONSTANT
13. what part of the experiment was pop..2? D. CONTROL
14. what part of experiment was caffeine? A. INDEPENDENT VARIABLE
Constant are those items that have been applied consistently w/o change.
Dependent variable are variables that change due to the application of independent variable.
Control is the basis of the experiment. It is what the result of the experiment is compared to, to check whether there are changes or not.</span>
The K.E. at the maximum height is zero, no matter what that height is.
Answer:
All the potential energy is converted to kinetic energy
Explanation:
As you contract your muscle, the energy stored within the fibers and cells of the static, relaxed muscle (this is potential energy) is converted into motion when the fibers are contacted. This motion corresponds to a kinetic energy.
The last two options can be discarded as follows:
-Energy can not be created nor destroyed. It can only be transformed.
-Heat is generated in most of the biochemical processes of the body. However, the heat release is not instantaneous and there are several other complex factors and phenomenae to consider. So, in accordance to the scope of this question, there is energy conservation and therefore all the energy is transformed from potential to kinetic, with no consideration of energy loss to the surroundings.
