Answer: True
Explanation:
A photo detector that can respond to the entire rang of visible light can be design, it is true.
Photo detector is a device in an optical receiver which receives optical signals and convert it to electric signal. It is the key device position in front of the optical receiver.
Answer:
8.5 ohms
Explanation:
from ohms law
V=IR
120=14.1R
divide both sides by 14.1
120/14.1=14.1R/14.1
R=8.5ohms
Answer:
Answer: Say the big boy is 40kg and the small boy is 20kg... ... ...then by the rule that moments around a fulcrum or pivot should be equal for equilibrium, the distance of big boy from pivot=half of dist of small boy from pivot
Magnetic moment of loop is given by the formula
now magnetic field is given here
Now the torque on the loop is given by
so above is the torque on the loop.
The results of the experiments should be similar.
