As accurately described by Einstein's theory of relativity, gravity is not necessarily a force, but a consequence of the curvature of space time that is caused by the uneven distribution of mass. But this could also be approximated by Newton's Law of Universal Motion. Gravity is a force acting upon two objects with masses at a certain amount of distance. So, the greater the mass, and the closer the objects are, the greater is the force of gravity. So, if you compare the gravity on Mars compared to Earth at a given distance, compare their masses. The mass of Earth is 5.972 × 10^24 kg while that of Mars is <span>6.39 × 10^23 kg. So, the gravity on Earth is much greater because Earth is heavier.
For the second question, let's base on Newton's Second Law of Motion which states: the force exerted on or by the object, is equal to its mass times acceleration. In equation, F = ma. So, if you want to increase acceleration, the force should be greater, while the mass should be lighter.</span>
CFCs, carbon dioxide, green house gases and it's effects are responsible for the hole in ozone layer.
You can reduce cultivated fallow
M = 600 kg
u = 0 (as the car was at rest initially)
v = 5 m/s
Initial kinetic energy = ½mu²
= ½×600×0
= 0
Final kinetic energy = ½mv²
= ½×600×25
= 7500 J
Hey there! :D
Force is energy or strength that as the characteristic of movement or physical action.
A push or pull is a force. It moves something physically. If I was going to push a door for it to open, I would physically be moving it.
Inertia is a common tendency to remain unchanged or do nothing. If you are not doing anything, you are not applying force or movement to anything. This would not be the correct answer. We can eliminate "C" and "E"
Since a push and pull both are a force, then "D" is the answer. They both are.
I hope this helps!
