Answer:
B. counterclockwise
Explanation:
We shall apply Lenz's law to find direction of induced current . According to it , direction of induced current is such that the magnetic field produced by it will try to nullify the change in magnetic field that produces it. Increase in magnetic field in down ward direction is producing it so to nullify it , magnetic field induced will be in upward direction. For it current induced will be anticlockwise.
Answer: Go ask your teacher and im sure if you search it on good it will answer faster than this.

Answer:
3) 52500N
Explanation:
We use the mathematical definition of impulse as follows;
were F is the force experienced, t is the time of impact, m is the mass of the object and v is the velocity of impact.
Given; m = 4.5kg, v = 35m/s, t = 3 milliseconds
however, 
From equation (1);
.
Substituting all necessary values into equation (2), we obtain the following;
