It takes 20347.4098071s for light from the sun to reach Pluto.
The 6.1*10^9 is replaced by 6.1*10^12 on line 4 because we convert the distance from km to m.
c = speed of light. If a different value was given in the previous question then use that instead of the value I used to do the final calculation.
PE=mgh
180=0.5*10*h
180=5h
h=180/5=36 m
I think one hour, sorry if i'm wrong
B.) 100 N is the CORRECT answer
Please mark as brainliest! :)
Well velocity is a vector quanity and we can brake vectors in to verticle and horizantal componontes threw these two formulas Vcostheta=Vx and Vsintheta=Vy
