Answer:
The magnitude of the average induced emf is 90V
Explanation:
Given;
area of the square coil, A = 0.4 m²
number of turns, N = 15 turns
magnitude of the magnetic field, B = 0.75 T
time of change of magnetic field, t = 0.05 s
The magnitude of the average induced emf is given by;
E = -NAB/t
E = -(15 x 0.4 x 0.75) / 0.05
E = -90 V
|E| = 90 V
Therefore, the magnitude of the average induced emf is 90V
It is gonna be C 0.37 and 19.1
One of the key differences between high density vs low density can liners is the sound and feeling. High density bags or can liners will have a more stiff feeling and sound "crunchier." In contrast, low density polyethylene bags will be much quieter to the touch and have a softer feel.
i hope this helped! :)

Answer:
65 miles
Explanation:
The distance travelled till 150 miles is
260 - 150 = 90
But as he walks back although his distance increase his displacement from initial point decrease.
Distance moved from 150 mile post to 175 mile post is
175 - 150 = 25
As he walks backwards in second time in consideration with first time to calculate the displacement we need to substract 90 from 25,
So displacement is 65 miles
