Answer:
0.05 W
Explanation:
The power dissipated by a device can be written as
where
P is the power dissipated
V is the voltage drop on the device
I is the current flowing through the device
In this problem, we have
V = 5.0 V is the voltage drop across the device
I = 10.0 mA = 0.01 A is the current through it
By applying the formula, we find the power dissipated:
Answer:
3N/C
Explanation:
Thinking process:
Let, electric field of 4N/C is in the positive x direction, that is + 4 NC
And the the resulting electric field on the x axis at x =2m
Therefore, based on the data above, the net charge must be in the positive direction. Thus, the magnitude is given by the equation:
Now considering that at x = + 4 NC, the net charge will be:
