Answer:
Number of electrons, 
Explanation:
It is given that,
Charge, q = 4.33 C
We need to find the number of electrons that make 4.33 C of charge. According to quantization of charge as :
n = number of electrons
e = electron's charge
So, the number of electrons are 
Hence, this is the required solution.
Since its a sphere, the top is seen first because its the tallest part if the ship. If the earth was flat, the whole ship would be seen.

Explanation:
conversion of 2.5 days to seconds
2.5 days =2.5 days*24 hours*3600 seconds
2.5 days=216000seconds
b) conversion of 25 km to mm
1 km=1000000 mm
therefore
25 km=25*1000000=25000000 mm
c) conversion 22 g to kg
1000 g=1 kg
therefore
22 g=22/1000=0.022 kg
