Adhesive.
Adhesive is the force of attraction between molecules of different kind. Liquid flows upward the wick because the adhesive force between the wick and the liquid is higher than cohesive forces in the liquid.
When the adhesive force between the wick and the liquid is high we have capillarity taking place. This cause the liquid to move up the wick.
Answer:
No force acts on it. It will not be pushed.
Explanation:
The proton moving in the -X direction implies its velocity is in the -X direction and the magnetic field is given to be in the +X direction. So the angle between them is 180 degrees. So no force acts on the proton, since the velocity and magnetic field are anti parallel.
Magnetic force is given by the equation F = q v B sin theta where theta is the angle between the velocity and the magnetic field. This force will be a maximum if they are perpendicular to each other.
Answer:
B. 75V
Explanation:
The formula for Voltage across and Inductor is given as:
Vr.m.s = Ir.m.s × XL
Where
Ir.m.s : Current across the inductor
XL = 2πFL
In the question we were given values
Ir.m.s = 0.20A
F = 750Hz
L = Inductance = 0.080H
Vr.m.s = 0.20 × ( 2 × π× 750Hz × 0.080H)
Vr.m.s= 0.20 × 376.99111843
Vr.m.s = 75.389223686volts
Approximately = 75volts
Therefore, the voltage across the inductor is 75 volts.
