the force of attraction between two masses is 3.60 Newtons if one of the masses is tripled and the distance between the masses is quadrupled what is the new force of attraction​

Answers

Answer 1

Answer: F = 19.2 N

Explanation: Given that the initial Force = 3.6N

The formula involved is

F = GMm/r^2

Substitute the force F

3.6 = GMm/r^2

If one of the masses is tripled and the distance between the masses is quadrupled. We have

3.6 = (G × 3Mm)/(4r)^2

Where G will be constant.

3.6 = 3GMm/16r^2

Separate the fraction of number

3.6 = 3/16 × GMm/r^2

Make GMm/r^2 the subject of formula

(3.6 × 16)/3 = GMm/r^2

19.2 = GMm/r^2

Therefore, the new force of attraction is 19.2 N

how has E=MC2 helped us with our understanding of how stars like our Sun create energy?

Answers

Answer: please find the answer in the explanation

Explanation:

E = MC^2

Where

E = energy

M = mass

C = speed of light.

This equation is an eyes opener about the relationship between matter and energy. Its explanation about how matter can become energy and how energy can also give information about matter.

It helps us to understand the fusion and fission of both sun and star particles which eventually give us the result of the magnitude of energy they emit or radiate.
