Answer:
(a) ΔФ = -0.109W
(b) emf = 28.43V
(c) Iin = emf/R
Explanation:
(a) In order to calculate the magnetic flux you use the following formula:
(1)
B: magnitude of the magnetic field = 1.40T
A: area of the rectangular coil = (0.23m)(0.34m)=0.078m^2
Where it has been taken into account that at the beginning the normal vector to the cross sectional area of the coil, and the magnetic field vector are parallel. When the coil is rotated the vectors are perpendicular.
Then, you obtain:

The change in the magnetic flux is -0.109 W
(b) During the rotation of the coil the emf induced is given by:
(2)
N: turns of the coil = 60
ΔФ: change in the magnetic flux = 0.109W
Δt: lapse time of the rotation = 0.230s
You replace the values of the parameters in the equation (2):

The induced emf is 28.43V
(c) The induced current in the coil is given by:
(3)
R: resistance of the coil (it is necessary to have this value)
emf :induced emf = 28.43V
The answer is C hope it helps
Answer:

Explanation:
Given that the operating cost is
cents per mile
total miles covered is given as

so total cost of drive is given as
$
time taken by the truck to move the distance is given as

So total earnings of the driver is given as
$
now total profit of the driver is given as
$
to maximize the profit we have


so we have
