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>
The answer is (A) the object must be at rest.
When all of the forces acting on an object balance, the net force is zero and hence the object will not move.
Yes, the direction might also change under some special circumstances.
Element 2 explanation just trust
<span>Recall formula for Kinetic energy is:
KE = 1/2mv^2, where KE = 275J
and momentum (which is 25.0 kg m/s) = m*v
Therefore substitute for KE and mv in the equation above to get speed
=> 275 = 0.5 * 25 * v
v = 275/12.5
v = 22m/s
to get mass m, recall momentum = m*v
=> 25= 22*m
m= 25/22 = 1.3663kg</span>
