Answer:
236.3 x 
C
Explanation:
Given:
B(0)=1.60T and B(t)=-1.60T
No. of turns 'N' =100
cross-sectional area 'A'= 1.2 x m²
Resistance 'R'= 1.3Ω
According to Faraday's law, the induced emf is given by,
ℰ=-NdΦ/dt
The current given by resistance and induced emf as
I = ℰ/R
I= -NdΦ/dtR
By converting the current to differential form(the time derivative of charge), we get
= -NdΦ/dtR
dq= -N dΦ/R
The change in the flux dФ =Ф(t)-Ф(0)
therefore, dq = 
(Ф(0)-Ф(t))
Also, flux is equal to the magnetic field multiplied with the area of the coil
dq = NA(B(0)-B(t))/R
dq= (100)(1.2 x )(1.6+1.6)/1.3
dq= 236.3 x C
Q = mc<span>∆t, where:
q = energy flow
m = mass, 120 000 g
c = specific heat capacity, 4.81 J/gC
</span><span>∆t = change in temperature, ~75 (100 - 25, which is room temperature)
Substituting in the values, we get:
q = 120000 x 4.81 x 75 = 43290000 Joules = 43.29 MJ
Hope I helped!! xx

Countries longer day for example in the Middle East could benefit more but Alaska has more night like longer night which is why it would hard to benefit from the solar panels there.
Hoped this helped
Answer: 6 times further
Explanation:
Initial velocity is the same that she uses on earth vertically and horizontally
Vertically we can say
V = -g t
If g is 1/6 earth gravity, then t is 6 times earth time.
Then, horizontally, with the same initial time, no incidence of gravity and knowing t
X= v t
Distance in the moon is 6 times distance in the earth.
Answer:
Ok, so the car has traversed a total of 2 + 4 + 2 + 6 = 14 miles.
That's the car's distance! :)
For the displacement, you can draw out a diagram. I'll try my best to make one using a keyboard xDDD
- - - - |
| |
| - - - start - end!
So, this is the journey of the car: Going two up, 4 left, 2 down, and 6 right.
This ends up 2 to the right of the beginning!
That's a 2 mile displacement :)
Can you give me brainliest for my splendid diagram? xD
