Answer:
2
Explanation:
agility is the ability to zoom fast and do fast zoomy stuff
The "energy" is actually gravity. When the moon is on one side of the Earth, this causes high tidal waves. Meanwhile, the other side that is morning would have low tides. The gravity belongs to the moon. Hope this helps.

This is an exercise in the conservation of momentum.
For this problem, I'll use the initial coordinates and velocity of the astronaut as my frame of reference because it makes the math easier. Due to the law of conservation of momentum, the momentum before and after the astronaut throws the wrench has to remain the same. And since I'm using the starting situation of the astronaut as my frame of reference, that value is 0. But thankfully, momentum is a vector quantity and we can save the astronaut.
The momentum of an object is mass times velocity. So the momentum of the wrench after being thrown is:
-19.6 m/s * 0.515 kg = -10.094 kg*m/s
Now to balance that, we need the astronaut to have a momentum of 10.094 kg*m/s which just happens to be the case (can't break the laws of physics). So let's do some division to get the velocity.
10.094 kg*m/s / 86.8 kg = 0.116290323 m/s
Yay! The astronaut is moving back to the shuttle at a reasonable velocity. But has 42.1 m to travel. Another situation for division:
42.1 m / 0.116290323 m/s = 362.0249653 s
So rounding to 3 significant digits gives a travel time of 362 seconds, or just a couple of seconds longer than 6 minutes.</span>
Answer:
Explanation:
The distance covered by the car is 1 meter.
The time taken for the car is 9 seconds.
The average velocity of the car is 1/9 m/s.
C.) The relationship between volume, temperature, pressure and quantity of moles is given by ideal gas law. Mathematically given by PV = nRT.
