PART A)
Here by force balance along Y direction

Force balance along X direction

now by torque balance



PART B)
now from above equations



now net reaction force of wall is given as


The planet closest to the sun; Mercury.
Answer:
80kg = 133 Newtons I'm pretty sure this is right.
Answer:
The correct answer is c. More total rainfall from a slower moving storm.
