Answer:
its frequency = 50 per second
Explanation:
Momentum (in terms of classical mechanics) is defined as p = m*v, where m is the mass and v is the velocity.

Answer:
a. Rods are about 1000 times more sensitive than cones.
Explanation:
The answer choice shown is a direct copy of the first line of the problem statement. It doesn't appear to be any more complicated than that. (It's a reading comprehension question.)
The emf induced = B*l*v where B is the flux density, l the length of the conductor and v the velocity of the conductor. In the given case B = 0.035 N/amp.meter, l = 0.86 and v = 6 m/sec
emf = 0.035*0.86*6 = 0.1806 v ≈ 0.18 v
choice: D
