Answer:
Yes
Explanation:
The visible light color spectrum only makes up a small segment of the EM spectrum
Answer:
<h2>Magnetic field strength in that region is 1.2 T</h2>
Explanation:
As we know by the formula of radius of charge moving in external field is given as

so we will have




now we have

now we have

Answer:
(a) 17450.8 J (B) 1.239 sec
Explanation:
We have given power output =8 KW
Heat expelled = 10994 j
Efficiency =37% = 0.37
(A) We know that efficiency 

Heat input =17450.8 J
(B) Work done by the engine is = 17450.8-10994=6456.8 j
Power output is given by 8 KW =8000 W
So time for each cycle is
