For Pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
which becomes
where
is the force on the first piston
is the area of the first piston
is the force on the second piston
is the area of the second piston
If we rearrange the equation and we use these data, we can find the intensity of the force on the second piston:
By adding up all the individual forces of the object
Answer:
D
Explanation:
Scientists use significant figures to avoid claiming more accuracy in a calculation than they actually know.
Definition: Momentum = (mass) x (speed)
OK. Here we go.
Watch closely:
Divide each side
by 'mass' : <span>Momentum / mass = Speed </span>
Did you follow that ?
Answer:
Explanation:
The magnetic field is straight up. It is reducing . As per Lenz's law , direction of induced current is such that it opposes the reason which creates it . magnetic field in upper direction is reducing . So current will be such that magnetic field produced by it increases magnetic field in upper direction . In other words , induced current should create magnetic field in upward direction. It is possible when direction of induced current is anti - clockwise, when seen from above.
