Answer:
Explanation:
An object will remain at rest or in uniform in a straight line upon an external force
<span>You can prove that moon is in motion by taking two photos with the following features:
They are taken at the same hour and minute.
They are taken on two different nights.
They are taken from the same location.
This would allow an accurate comparison and would should the moon's motion.
I hope this helped! :)</span>
Answer:
c. Equal to the weight of the block.
Explanation:
We know that when an object floats , the displaced water by the floating body
has weight equal to the weight of the body . In this condition the upthrust becomes equal to the weight of the body .
In the present case the beaker is full to the brim with water . Then the body was made to float into it . While attaining equilibrium in water , it displaces water whose weight must have been equal to its weight . That liquid got spilled over the edge and collected on the tray .
So water collected on the tray must be equal to the weight of the body floating.
Electric field strength near the surface of sphere is given by
Now we have
Q = 1 C
R = 5 cm
now electric field is given by
Part B)
Since charge on the sphere is very large to electric field near its surface is too high. So this is reasonable result near it.
Part c)
As per our assumption the charge is uniformly distributed on the surface and there is no effect of surrounding charge or surrounding electric field.
The answer is A. The distance traveled by the wave during one full cycle
