86,400 is the amount of seconds in a day. :)
Hence the period is 1 sec.
<u>Explanation</u>:
- If the time taken by a single pendulum is 0.25 seconds. Then a pendulum will move to two extreme positions from one mean position only. That will means that the total time period is given by
T = 2
0.25 = 0.50 seconds.
- A pendulum will oscillate from mean to the extreme, then extreme to mean, then mean to the extreme and again extreme to mean, so it will cover 2 cycles.
Hence, 2
0.50 = 1.

Answer:

Explanation:
Given that:
thickness of the metal strip, 
width of the metal strip, 
magnitude of the perpendicular magnetic field, 
current through the strip, 
charge density, 
Hall voltage is a transverse voltage given by:

putting the respective values


Note:
V = E d is used when a charge is moved in a uniform electric field between the two oppositely charged plates, it can't be used here because it is the case of Hall effect where the small voltage develops transverse to the direction of current flow.
