Answer:
Q = 114895 J
Explanation:
To find the thermal energy gained by the ice you use the following formula:
m: mass of the ice = 0.250kg
T2: final temperature = 22°C
T1: initial temperature = -8.0°C
Hf: heat of fusion of water = 3.34*10^5 J/kg
c: specific heat of water = 4186 J/kg
By replacing the values of the parameters you have:

Net force acting on the car is 3 x 10^3 Newtons:
The answer is supposed to be during the summer in Richmond,
the angle of the sun at noon from the vertical is 14 degrees which is equal to
Richmond's latitude of 37.5 degrees minus Earth's slope of 23.5 degrees. While in the winter, the angle of the sun at
noon from the vertical is 61 degrees.
