Answer:
Explanation:
Given
mass of object is m
Mass of planet is M
radius of planet is R
Total Energy associated with mass m at a height h above planet is Gravitational Potential Energy which is given by
When it falls on earth with some velocity v
=Kinetic Energy+Potential Energy
As Energy is conserved therefore
Answer:
The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars. After an asteroid belt comes the outer planets, Jupiter, Saturn, Uranus and Neptune
Explanation:
Answer:
45 kg is the mass of a table that weights 441 newton.
-- The acceleration of gravity (on Earth) is 9.8 m/s².
-- That means that during every second an object falls,
it adds 9.8 m/s of speed.
Now ! If it adds 9.8 m/s of speed every second, then
how fast is it falling at the end of 3.4 seconds ?
This is as close as I can bring you to the answer
without dropping it at your feet, or handing it to you
on a golden tray.
The force of attraction or repulsion between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them and acts along the line joining the two charges . F=k Q1Q2/r^2
