Answer:
Complete question:
c.If the current in the second coil increases at a rate of 0.365 A/s , what is the magnitude of the induced emf in the first coil?
a.
b.flux through each turn = Ф = 
c.magnitude of the induced emf in the first coil = e= 
Explanation:
a. rate of current changing = ![\frac{di}{dt}=[tex]M=\frac{1.60\times10^{-3} V}{0.240\frac{A}{s} }}](https://tex.z-dn.net/?f=%5Cfrac%7Bdi%7D%7Bdt%7D%3D%5Btex%5DM%3D%5Cfrac%7B1.60%5Ctimes10%5E%7B-3%7D%20V%7D%7B0.240%5Cfrac%7BA%7D%7Bs%7D%20%7D%7D)

Induced emf in the coil =e= 
For mutual inductance in which change in flux in one coil induces emf in the second coil given by the farmula based on farady law
b.
Flux through each turn=?
Current in the first coil =1.25 A
Number of turns = 20
using MI = NФ
flux through each turn = Ф = 
flux through each turn = Ф =
c.
second coil increase at a rate = 0.365 A/s
magnitude of the induced emf in the first coil =?
using 
magnitude of the induced emf in the first coil = e=
Answer:
The correct answer would be B.
Explanation:
I believe the answer is B because for electrical energy you would need electric charges to be moved by kinetic energy.
Answer:
approx 6 × 10^24 kg is earth's mass
Answer:
the tension in each side of the cable is 3677.57 N
Explanation:
given data
traffic light = 20 kg
cable between two poles = 30 m
sag in the cable = 0.40 m
solution
by the free body diagram
tan θ = 
.............1
θ = 1.527 °
and
tension = mg
The net force is along x - axis is express as
T2 cosθ = T1 cosθ .................2
so T2 - T1 ..............3
and
when we take it along y axis that is express as
( T1 + T2) sinθ = mg ...................4
so by equation 3 we put here
2 × T1 sin(1.527) = 20 × 9.8
T1 = 3677.57 N
The initial velocity of the potato is 54.41 m/s.
The given parameters:
- <em>Mass of the potato, m = 0.34 kg</em>
- <em>Mass of the cart, m = 5.0 kg </em>
- <em>Velocity of the recoil, u₂ = 3.7 m/s</em>
<em />
The initial velocity of the potato is calculated by applying the principle of conservation of energy as follows;
Thus, the initial velocity of the potato is 54.41 m/s.
