Through is the answer to your question
Q stands for heat energy (Joules) hope this helps!
Answer:
a). 1.28333 seconds
b). 186.66 seconds
Explanation:
a). Given :
Distance between the earth and the moon, d =
m
Speed of the radio waves, c =
m/s
Therefore the time required for the voice of Neil Armstrong to reach the earth via radio waves is given by :


= 1.28333 seconds
b). Distance between Mars and the earth, d =
m
Speed of the radio waves, c =
m/s
So, the time required for his voice to reach earth is :


= 186.66 seconds
