Answer:
conductor, insulator, resists, semiconductor, 3 and 5 group
Explanation:
-45N because you add the side together and make it equal 0
Answer:
0.04973 W
Explanation:
I = Intensity of laser =
(assumed, as it is not given)
d = Diameter of spot = 1.31 mm
r = Radius = 
A = Area = 
Power is given by

The power output of the laser is 0.04973 W
Choice ' C ' is a correct statement.
The other choices aren't.
Answer:
2440 N
Explanation:
As,F=m*a.....
From the question we have
force = 976 × 2.5
We have the final answer as
2440 N
