Answer:
ФE = 9.403W
Explanation:
In order to calculate the magnitude of the electric flux trough the sheet, you use the following formula:
(1)
A: area of the rectangular sheet = (0.400m)(0.600m) = 0.24m^2
E: magnitude of the electric field = 95.0N/C
θ: angle between the direction of the electric field and the normal to the surface of the sheet
You replace the values of the parameters in the equation (1):
The magnitude of the electric flux is trough the sheet is 9.403W
Answer:
Explanation:
As we know that car is moving in the curve of given radius
So the force on that car is given as
So for the first car we have
for other car we will have
now we will have
Answer:
I = 0.2 A
Explanation:
The current flowing across each resistor in a series arrangement is the same throughout the circuit. So in order to calculate the current, we must first find the equivalent resistance of all three resistors. The equivalent resistance of the resistors connected in series is given as:
Now we use Ohm's law for the current:
<u>I = 0.2 A</u>
Answer:
<em>Venus will need to use more voltage to have the same current</em>
Explanation:
<u>Ohm's Law</u>
It states that the current through a conductor is directly proportional to the voltage applied to it and inversely proportional to the resistance of the conductor. This relationship can be written as
Solving for V
Venus originally connected a resistance to a voltage to get some current I
The voltage needed to get that current is
If Venus changes the light bulb to another with higher resistance, say, , then the current would change, unless she uses another voltage
Venus will need to use more voltage to have the same current
