The plastic rod is made of insulator (plastic), so it does not allow charges moving from one sphere to another. This means that all the electrons given to sphere A will remain on sphere A.
The number of electrons initially given to sphere A is
, and since the charge of 1 electron is
, the net charge left on sphere A after the removal of the rod will be
Because there is water everywhere by which the water gets hot and vaporised so that's why near the sea temperature is low.

Answer:
12 m/s
Explanation:
Given data
Mass m= 1500kg
intitial velocity u= 20m/s
force F= 6000N
time t= 2 seconds
Required
The final velocity v
From
Ft= mΔv
Ft= m(u-v)
substitute
6000*2= 1500(20-v)
solve for v
12000= 30000- 1500v
collect like terms
12000-30000= -1500v
-18000= -1500v
divide both sides by -1500v
v= 18000/1500
v=12 m/s
Hence the velccity is 12 m/s
