Ocean currents are caused by density differences in the water and move water masses through the deep ocean
Answer:
Explanation:
The capacitance of the parallel-plate capacitor is given by:
where
is the vacuum permittivity
is the area of the plates
is the separation between the plates
Substituting,
The energy stored in the capacitor is given by
Since we know the energy
we can re-arrange the formula to find the charge, Q:
To solve this problem we will make a graph that allows us to understand the components acting on the body. In this way we will have the centripetal Force and the Force by gravity generating a total component. If we take both forces and get the trigonometric ratio of the tangent we would have the angle is,
Dividing both.
Therefore the angle that should the curve be banked is 15.608°
Paul the penguin's velocity is 3.33.
<u>Explanation:</u>
Paul glided (displaced) 40 meters towards north.
The time he taken to displace is 12 seconds.
∴displacement d= 40m.
time t= 12s.
The speed of a body in a certain direction is the measure of Velocity.
The velocity of the an moving object is given by ratio of the rate of change in the distance by the time taken.
⇒Velocity v= .
=.
=3.33 .
Thus the velocity of the Paul the penguin glided on ice is 3.33 .
Answer:
Explanation:
As we know that when electron moved in electric field then work done by electric field must be equal to the change in kinetic energy of the electron
So here we have to find the work done by electric field on moving electron
So we have
now the distance moved by the electron is given as
so we have
now we have to convert it into keV units
so we have
