If total charge Q is enclosed in the surface of cube
then we will have say that total flux linked with all surfaces of the cube will be given by
since the position of charge is symmetric with respect to the center of the cube so here this whole flux will be equally linked with each of the face of the cube
So here total 6 faces of the cube is there and the total flux of the charge will equally divide in these 6 faces
so flux linked with each face is given by formula
so each face will have above flux due to central position of charge Q
The correct answer is
<span>C) Amount of heat absorbed or released is doubled if quantity is doubled. If a different substance with half the specific heat capacity is used, the amount of heat absorbed or released is cut in half.
In fact, the amount of heat released or absorbed is given by:
</span>
<span>where
m is the mass of the substance
Cs is the specific heat capacity of the material
</span>
is the change in temperature
<span>
We can see that Q is directly proportional to both m (mass, or quantity of the substance) and Cs (specific heat capacity). So if the quantity (m) is doubled, the amount of heat (Q) is doubled as well. Similarly, if the specific heat capacity (Cs) is cut in half, the amount of heat (Q) is cut in half as well.</span>

Answer:
297.8 m
Explanation:
We are given that
Acceleration=
Time,t=19 s
We have to find the distance covered by the train when it reach its top speed if starting from rest.
Initial speed=u=0
Using the formula
Hence, the train covered 297.8 m when the train go to reach its top speed if starting from rest.
