An apple hanging from a tree 3 m high has a potential energy of 6 J. What is the mass of the apple?

m= 0.20 Kg

Explanation:

Given: F = 6 J, a = 3 m

To find: What is  the mass of the apple?

Formula:

Solution: Newtons are derived units, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared.

M = F ÷ a

F = 6 kg ÷ 3 m/s2

F = 2 N

PE = mgh 6 J= (3m) (9.8 m/s2²) (__m) m= 0.20 Kg

they emit helium gas that attaches to nearby planets.

they remove low-mass elements from the planets’ crust.

they cause nuclear fusion inside the inner core of planets.

they produce heavy elements such as iron and gold.

explanation:

they are all solids.
