Answer:

Acceleration due to gravity, $a=4.61\times 10^{-14}\ m/s^2$

Explanation:

It is given that,

Mass of Pluto, $m=1.4\times 10^{22}\ kg$

Distance between Neptune and Pluto, $r=4.5\times 10^{12}\ m$

The force of gravity is balanced by the gravitational force between Neptune and Pluto. It is given by :

$a=\dfrac{Gm}{r^2}$

$a=\dfrac{6.67\times 10^{-11}\times 1.4\times 10^{22}}{(4.5\times 10^{12})^2}$

$a=4.61\times 10^{-14}\ m/s^2$

So, the acceleration due to gravity at Neptune due to Pluto is $4.61\times 10^{-14}\ m/s^2$ . Hence, this is the required solution.

If the mass of an object stays the same and you apply more force what will happen to the objects motion

vovikov84 [41]

it will move the object if you apply force, because of that it will stay the same with newton's law.

Answer:

Synthetic Materials are man-made; natural materials are only warmer than synthetic materials, if the natural material is obtained from an animal. Wool is warmer than any synthetic material available, but polyester (a synthetic material) can be warmer than cotton (a natural plant-based material).

A DC motor with a ticking sound that corresponds with a discolored commutator bar rotating under the brushes. The problem is mos

sukhopar [10]

The problem is most likely that the commutator brushes bounces as the motor shaft rotates.

<h3>What is a DC motor?</h3>

This is referred to a device which converts direct current electrical energy into mechanical energy.

if the commutator brushes bounces as the motor shaft rotates over different materials, the ticking sound is heard.
