(a) The emf induced in the wire is 0.112 V.
(b) The direction of the current will into the page.
(c) The polarity of A will be positive and L will be negative.
(d) The current flowing through the wire is 0.224 A.
<h3>
EMF induced in the wire</h3>
The emf induced in the wire is calculated as follows;
EMF = BLv
EMF = (8 x 10⁻²) x 0.2 x 7
EMF = 0.112 V
<h3>Direction of the current</h3>
Since, the magnetic field is out of the page, the current will follow counter clockwise and will point into the page.
<h3>Polarity of point A and point L</h3>
The current is flowing counter currently, hence the polarity of A will be positive and L will be negative.
<h3>Current through the wire</h3>
V = IR
I = V/R
I = (0.112)/0.5
I = 0.224 A

Answer:
The two helicopters have the same kinetic energy, but a different GPE, or gravitational potential energy.
Explanation:
2m/s^2, this is because F=ma, meaning a is also equal to F/m. The car applies 1500N in one direction and outside sources apply a total of -500N, meaning the 500kg car is moving forward with a total of 1000N of force. Taking the total 1000N and dividing it by 500kg gives you and acceleration of 2m/s^2. Hope this helps!
