use formula Ep=mgh
Explanation:
potential energy is being utilized
Answer:
Mutations do not necessarily always have to be bad, sometimes plants or animals mutate with something helpful to the situation they are in.
If a coin is dropped at a relatively low altitude, it's acceleration remains constant. However, if the coin is dropped at a very high altitude, air resistance will have a significant effect. The initial acceleration of the coin will be the greatest. As it falls down, air resistance will counteract the weight of the coin. So, the acceleration will decrease. Although the acceleration decreases, the coin still accelerates, that is why it falls faster. When the air resistance fully counters the weight of the coin, the acceleration will become zero and the coin will fall at a constant speed (terminal velocity). So, the answer should be, The acceleration decreases until it reaches 0. The closest answer is.
a. The acceleration decreases.
F=ma = 1000kg * 9.8 m/s^2 = 9800 N
What counteracts gravity is buoyancy.
