Potential energy = mgh
Potential energy = 10 x 9.8 x 1.3
Potential energy = 127.4 J
In a moving car the outside looks to be moving. however if viewed from the outside, the car appears to be moving. so motion is relative to the person observing.
Answer:
The pressure remains the same.
F = P * A the amount of force transmitted would double if only the input area is changed. Pressure is the same at all points in the system.
Answer:
Force of gravity
Explanation:
when the force of gravity pulls large gas clouds and dust together, the concentrated gas clouds and dust collapse under the force of gravity forming stars.
There are many galaxies out there in the universe, each galaxy has its own solar systems, stars, and collection of gas and dust. We (earth) belong to the Milky Way galaxy, our galaxy got this name from the Romans. They called in 'via lactea', which directly translates to 'road of milk' because of the milky patch they saw at night.
Answer:
