When the absorption or emission lines of a moving object away from from the earth at very high speed then the spectral lines will be shifted toward the red end of the spectrum.This effect can be easily understand by Doppler effect..

So the our option c is correct.

c. They will be shifted toward the red end of the spectrum.

What power rating of resistors would you use in the application required it to handle<br> 0.6W?

aliya0001 [1]

I would use a resistor rated for 1 W or more. Not less.

What is the gpe of a 200 kg hot air ballon 21,000 m above the ground?

stiv31 [10]

gravitational Potential energy is given by

$GPE = mgh$

here we have

m = 200 kg

h = 21000 m

now we will have

$GPE = 200(9.8)(21000)$

$GPE = 4.116 \times 10^7 J$

so GPE of balloon will be 41160000 J above the given height from ground
