Explanation:
Answer: 31.85 m/s
Explanation:
Since we are talking about constant acceleration, we can use the following equation to find the speed
of the rocket:

Where:
is the distance the rocket has traveled
is the time in which the rocket has traveled the distance 
Solving the equation with the given data:

This is the rocket's speed
Answer:
14.9 m /s
Explanation:
n = n° x v /[ v -v (s) ]
n is apparent frequency , n° is source frequency,v is speed of sound and v(s)
speed of source.
2300 = 2200 x 343 / [343 -v(s)]
v (s ) = 14.9 m /s.
Because it's closest to the Sun. The side that Sun shines on is very hot and the side in shadows is very cold. Dont know the temps from top of my head
