Answer:
d = 4.9 m
Explanation:
It is mentioned that a stone is dropped from a certain height. It is required to find the distance covered by it in one second.
The initial speed of the stone is equal to 0 as it was at rest. Let d is the distance covered by the stone.
Using second equation of motion :
Put u = 0 and a = g
So, the distance covered by it in one second is 4.9 m.

Answer:
Cause its scalar quantity
Explanation:
since speed does not take directions into consideration, it is considered to be a scalar quantity. On the other hand, the velocity of an object does not take into account direction, thus making it a vector quantity.
Answer:
a) V = 252 cm³
b) Vs = 72 cm³
Explanation:
a)
The volume of the water can be given by the following formula:
<u>V = 252 cm³</u>
<u></u>
b)
The volume of stone can be given by the change in volume of the water when the stone is dipped into it.
<u>Vs = 72 cm³</u>
