Two masses, m1 and m2 are separated by a distance, r. The force of attraction between the two masses is F. Show all work
A) If m1 increases by 9, how does F change?

B) If r is halved (1/2), how would F change?

C) If r is not changed but both masses increase by a factor 7, how would F change?

D) If both m1 and m2 remain unchanged, and r changes to 3/5 of the original distance, how would F change?

E) If all variables (r, m1 and m2) increase by 4, how would F change?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

answer; how far out of place which the object finished relative to the starting location;
