Answer:
if one bulb burns out, the other bulbs in the fixture continue to operate. Other uses include an electronic OR gate, where two switches are in a parallel circuit: one of the switches must be closed for the circuit to function.
(2π rad/year) x (1 yr/365 days) x (1 day / 86,400 seconds)
= (2π) / (365 x 86,400) rad/sec
= 0.000 000 2 radian/sec
= 0.2 microrad/sec
Answer:
60 N
Explanation:
because when we double the 30N, we will get 60N as a force
Answer:
Explanation:
By Snell's law we know at the left surface
now we have
now on the other surface we know that
angle of incidence = 
so again we have
so we have
also we know that
By solving above equation we have
