Answer:
0.405 V
Explanation:
Using Faraday-Lenz law, the emf induced in the coil is given by

where
is the change in flux linkage through the coil

is the time interval
The change in flux linkage can be written as

where
N = 200 is the number of turns
is the area of the squared loop
Bi = 0.50 T is the initial magnetic flux density
Bf = 0.00 T is the final magnetic flux density
Substituting everything into the first equation, we find

Answer:
1.67 m/s
Explanation:
Momentum is conserved.
Initial momentum = final momentum
(30 kg) (10 m/s) + (35 kg) (-10 m/s) = (30 kg) v + (35 kg) (0 m/s)
300 - 350 = 30v
v = -5/3 m/s
Linus will move at 1.67 m/s in the direction opposite that he started.
