At First, there is chemical Energy( in your muscels) which is Used to Push down the spring. This Energy becomes the Energy of the spring, which increases until you stop pushing. If you Put your hand away, the Energy of the spring will become kinetic energ. This Energy is at the highest Level the Moment the book ist Leaving the spring. Afterwards, the kinetic Energy decreases while the Gravitational Potential Energy increases.

quizlet
The answer is B . You begin with a purpose for the lab, then hypothesize on what you believe will happen. Next, follow the procedures. This is always the last step, Anatoly did. Reflect upon you hypothesis, did the lab support or disprove your hypothesis. Include observations you have made. Identify errors.
Answer:
20 kg
Explanation:
Kinetic energy=½*Mass * velocity²
4000= ½* m*20²
8000=400m
m=8000/400
m=20 kg
The Bernoulli's principle is <span>the principle in hydrodynamics that an increase in the velocity of a stream of fluid results in a decrease in pressure.</span>
