Answer:air flow and the movement from where it’s coming from
Explanation:
Answer:
i = 0.5 A
Explanation:
As we know that magnetic flux is given as
here we know that
N = number of turns
B = magnetic field
A = area of the loop
now we know that rate of change in magnetic flux will induce EMF in the coil
so we have
now plug in all values to find induced EMF
now by ohm's law we have
To get the solution you must need to draw a force triangle. Attach the head of the 60N north force arrow with the tail of the 60N east force arrow. The subsequent is the arrow connecting he tail and head of the two arrows.
You get a right angled triangle, and the resultant is (60^2 + 60^2) ^0.5 = 84.85 N or 85 N northeast.
Carbon isn’t because all the others on the list are naturally made apart from carbon which is man made because of all the pollution . X
Answer:
It would take time for the capacitor to discharge from to .
It would take time for the capacitor to discharge from to .
Note that , and that.
Explanation:
In an RC circuit, a capacitor is connected directly to a resistor. Let the time constant of this circuit is , and the initial charge of the capacitor be . Then at time , the charge stored in the capacitor would be:
.
<h3>a)</h3>
