Hey, I think someone should help u cause I’m stuck too
Hope this helps !
Answer:
This is an astrophysics question and we will use the following formulas to get the time 't' it will take the sun to move a distance equals to it's own diameter 'd'.
Recal:
ω = 2π rads,
Then the earth's angular velocity will be,
ω = (2πrads / (24h * 3600s/h)) = 7.27x10⁻⁵ rad/s
and note that the Angular Acceleration
∅= ω*t
9.28x10⁻³rads = 7.27x10⁻⁵rads x t
t = 127 s
Hence, the time (in seconds) it take for the sun to move a distance equal to its own diameter = 127seconds
Answer:
The distance traveled!

This is a velocity time graph of an object moving in a straight line due North.
Answer: #4
Sally is faster.
Explanation:
If you multiply Sallies it is going to be less than Jessica's.
Stephen`s Law:
P = (Sigma) · A · e · T^4
P in = P out
e = 1 for blacktop;
1150 W = (Sigma) · T^4
(Sigma) = 5.669 · 10 ^(-8) W/m²K^4
T^4 = 1150 : ( 5.669 · 10^(-8) )
T^4 = 202.875 · 10^8
T = 3.774 · 10² =
377.4 KAnswer: Equilibrium temperature is 377.4 K.
