Answer:
d. 332 V
Explanation:
Given;
number of turns in the wire, N = 40 turns
area of the coil, A = 0.06 m²
magnitude of the magnetic field, B = 0.4 T
frequency of the wave, f = 55 Hz
The maximum emf induced in the coil is given by;
E = NBAω
Where;
ω is angular velocity = 2πf
E = NBA(2πf)
E = 40 x 0.4 x 0.06 x (2 x π x 55)
E = 332 V
Therefore, the maximum induced emf in the coil is 332 V.
The correct option is "D"
d. 332 V
Answer:
Explanation:
As we know that mass is the product of volume and density
so we will have
here we have
so we will have
so we will have
now let the position of Pluto is at origin so we have
Answer:

Explanation:
Given:
deceleration,
a = 22 ft/sec²
Initial velocity,
Now,
Now,
Final velocity,
Initial velocity,
hence,
⇒
By putting the values, we get
Hello there!
The formula for Force is F = MA, or
Force = Mass x Acceleration
Well, since we have a rock falling in free fall, we can use the magical number 9.8 m/s^2 (also known as gravity). We have our value for force, 147N (Newtons).
So now, we have the value of our acceleration, A, and our value of the force, F, in our formula.
147 = 9.8M
To solve for M, we need to divide 147 by 9.8.
147/9.8 = 15
This means our Mass is 15 kg (remember your units!)
I hope this helps!
