<span>Answer: Force = 81.6 N
Explanation:
According to Newton's Second law:
F = ma --- (1)
Where F = Force = ?
m = Mass = 68 kg
a = Acceleration = 1.2 m/s^2
Plug in the values in (1):
(1) => F = 68 * 1.2
F = 81.6 N (The force needed to accelerate the skier at a rate of 1.2 m/s^2)</span>
Answer:
The Kinetic Energy decreases. The Total Energy stays the same
Explanation:
The TE stays the same, so if PE increases then KE will decrease.
The answer is C. Answers A, B and D all require physics to answer. Answer C is related to Chemistry because it involves atoms and from the sound of it the fission of them because two One Hidrogen and two oxygen are required to make H2O - Water
The one in the water would have a much greater speed than the one in the air since energy is transmitted better and faster in liquid than gas.
Pressure and number of molecules of gas,volume and number of molecules of gas.
