you can find it using the equation: potential energy=mass*gravitational acceleration*height.
energy=50kg*9.8N/kg*40m=19600Nm=19600J or 19.6kJ
Sometimes they use 10 instead of 9.8 for the g constant.

The gravitational force exerted on the satellite is called the centrifugal force, the force keeping it orbiting to the planet. Its formula is F= mass times the square of the velocity all over the radius.Thus,
F = 2400 * 6670^2 * (1/8.92x10^6)
F = 11,970 N
I hope I was able to help you. Have a good day.
A transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction. Transformers are mainly used to increase or decrease voltage in power lines or electric power applications. So your answer would be D. transformer
True
1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second each second.
