Since the density of the substance is ρ (rho),

==> every cm³ of this substance has ρ grams of mass.

Then

==> V cm³ of it has ρV grams of mass. That's ' m '.

and

==> 3V cm³ of it has 3ρV grams of mass. That's ' <em>3m</em> '.

The acceleration due to gravity on the moon is about 1/6 of the acceleration due to gravity on the earth. A net force F acts hor

uysha [10]

Answer:

c. $a_m$

Explanation:

We are given that

Acceleration due to gravity on the moon= $a_m$

Acceleration due to gravity on the earth= $a_e$

$g_m=\frac{1}{6}g_e$

Net force due to am on an object on moon= $F_{net}=ma_m$

There is no friction and no drag force and there is no gravity involved

Then, the force acting on an object on earth= $F=ma_e$

$F=F_{net}$ (given)

$ma_m=ma_e$

$a_e=a_m$

Hence, option c is true.
