so the distance is
Answer:
Explanation:
(a) The force of gravity is called an attractive force because it is the force (although weak) in which a planetary body or matter uses to attract an object towards itself.
(b) Yes, it does and the formula for force of gravity between any two object is
F = G
where m1 and m2 are masses of the first and second object respectively
r is the distance between the center of the two masses
G is the gravitational constant
Answer:
Explanation:
Given
mass of disk 
diameter of disc 
Force applied 
Now this force will Produce a torque of magnitude



And Torque is given Product of moment of inertia and angular acceleration 

Moment of inertia for Disc 



Answer:
a. 25000J or 25KJ
b.2500w
Explanation:
a. since we say work is force applied in the same line or straight line
<em>W=</em><em>F(</em><em>newtons </em><em>)</em><em>*</em><em>D(</em><em>metres</em><em>)</em><em> </em>
<em>b.</em><em> </em><em>power </em><em>is </em><em>work </em><em>over </em><em>time </em>
