0.031 kilometers or 31/1000 kilometers
Answer:
finish at the same time
Explanation:
Force equals mass times acceleration. Without friction the net force on both will be equal to component of the force of gravity. Therefore the net force will be mass time acceleration due to gravity times the incline of the hill. Since net force equals mass times acceleration. Now we set net force equals mass times acceleration and the mass will cancel out giving both block the same acceleration and therefore they will finish at the same time
Answer:
The mass of the feather would be 0.0075 kg.
Explanation:
If the feather were to be on earth, it would have experienced the gravitational pull of the earth downwards. So that from Newton's second law of motion,
F = mg
where f is the force on the object, m is the mass of the object and g is the acceleration due to gravity of the earth.
But, F = 0.075 N, g = 10 m/.
So that,
0.075 = m x 10
m =
= 0.0075 kg
The mass of the feather would be 0.0075 kg.

The force between two celestial bodies is a Newtonian gravitational force.
It is also called Newton's law of universal gravitation. We can write it down mathematically in the following way:
We can see from this formula that gravitational force is <span>inversely proportional to the square of the distance between bodies.
The electrostatic force between two charges is Coulombs force. We can write it down like this:
</span>
This force is also inversely proportional to the square of the distance between interacting particles.
The nuclear force is a little bit more complicated. It can be expressed using the so-called Yukawa potential, which has the following form:
This interaction does not follow the inverse-square law.
The final answer should be 8.
