The pressure of a liquid on the surface of its container or on the surface of any body in the liquid is equal to the weight of a column of the liquid whose height equals the depth of the liquid at that certain point.
Answer:
Bowl will have maximum potential energy
Explanation:
It is the bowl that will have maximum potential energy.
It is because potential energy is high when both height and mass of the object is high.
Here in this case the bowl has maximum weight with maximum height except the tea cup but the potential weight of cup will not make much impact as its weight is very low.
Answer: counterclockwise
Explanation:
As the area of the loop decreases steadily, the flux through the loop also decreases. By Lenz’s law, any induced current will tend to oppose the decrease. Using Flemming right hand rule (Fleming's right-hand rule which shows the direction of induced current) we know that magnetic field inside the loop due to a counterclockwise current comes out of the plane. Therefore a counterclockwise current will create a stronger magnetic field inside
the loop, tending to increase the flux.
When a wire loop is moved in the direction of the current or a wire loop is being pulled through a uniform magnetic field there would be no induced current ( current loop is said to be zero)
F- force on the object,
m - mass of the object:
F = 12 N = 12 kgm/s², m = 2 kg
F = m · a
a = F : m = 12 N : 2 kg = 6 m/s²
Answer: C)
