The answer is approximately 2.998e+8
Answer:
Yes
Explanation:
Gravity and forces form the axle (external forces) do not cause forces that tend to cause rotation around the turntable's axle.
Answer:
(C) Equal to 1.44 watt
Explanation:
We have given energy dissipated through the resistor = 1.44 watt
We have to find the energy supplied by the battery
From Telegence theorem we know that energy dissipated through resistor is equal to the energy supplied
As energy supplied is given as 1.44 watt
So energy supplied by the battery will be equal to 1.44 watt
So option (c) will be correct answer
<h2>Correct answer:</h2>

<h2>Explanation:</h2>
We can use voltage divider to solve this problem that is defined as the passive linear circuit producing an output voltage
that is a fraction of its input voltage
. So we can use the formula:

Answer:
39.375 A
Explanation:
To find the induced current, we use the relation
e = -ΔΦ/Δt, where
ΔΦ = change in magnetic flux of the bracelet
Δt = change in time, = 20 ms
Also, Φ = A.ΔB, such that
A = area of the bracelet, 0.005m²
ΔB = magnetic field strength of the bracelet = 1.35 - 4.5 = -3.15 T
ΔΦ = A.ΔB
ΔΦ = 0.005 * -3.15
ΔΦ = -.01575 wb
e = -ΔΦ/Δt
e = -0.01575 / 20*10^-3
e = 0.7875 V
From the question, the resistance of the bracelet is 0.02 ohm, so
From Ohms Law, I = V/R
I = 0.7875 / 0.02
I = 39.375 A
