Help thanks! have a great day

Both the mass and distance will affect the gravitational strength of an object to another object

Explanation:

Both the masses of the objects and the distance between them

Explanation:

F=(G*m1*m2)/(r^2))

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
