The surface temperature of the star increases when it changes its colour changes from red to blue.
Blue>white>yellow>orange>red
The given series is the temperature decreasing order of stars. Now our sun is considered as a yellow star.
Explanation:
formula for energy is k. e = ½mv²
m= 9
v= 75
k. e = ½×9×75 =337•5
19-? Is the exact p.d across the 114-?resistor.
Current will different
But p.d will same in parallel circuit .
I agree the best choice is A............
