Answer:

Explanation:
Given that,
Mass of the Moon, 
Mass of the person, m = 66 kg
The radius of Moon, 
We need to find the force between the person and the Moon. The formula for the gravitational force is given by :

So, the required force is
.
4 Hz is the difference between 510 and the unknown.
<span>Therefore the unknown is either 514 or 506. </span>
<span>If 505 and 506 were struck together, the diff would be 1 Hz </span>
<span>If 505 and 514 were struck toghether, the diff would be 9 Hz which would be difficult to count accurately, </span>
<span>Therefore the unknown is 514</span>
Answer:
There is much more friction on the rough surface than there is on the smooth surface.

Answer:
calculate the cars acceleration usingv=u+at
Explanation:
m/s. After 5 s the car reaches the bottome of the hill. Its speed at the bottom of the ... accelerating left a rownie. 10. A cart slows down while moving away from the ... does it need to accelerate to a velocity of 20 m/s
If the fulcrum is closer to the effort, then the load will move a greater distance. A pair of tweezers, swinging a baseball bat or using your arm to lift something are examples of third class levers.
