An apple in a tree has a gravitational potential energy of 175J and a mass of 0.36g. How high from the ground is the apple

h = 49,552.61 meters

Explanation:

Data:

Potential Energy = P.E = 175 J

Mass = m = 0.36 g = 0.36 ÷ 1000 (conversion from grams to kilograms for Standard Unit

                = 0.00036 Kg

Gravity = g = 9.81 m/sec²

Height = h = ?

Solution:

The formula for the Potential Energy is;

P.E = mgh

Putting the values in the above formula, we get;

175 = 0.00036 × 9.81 × h

h = (175)÷(0.00036 × 9.81)

h = 49,552.61 m

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate
