Answer:
Physics is the answer to all the forces in nature and it is important to know all of that in a day to day life to succeed in life
Explanation:
There's no air in space, so there's no air resistance there.
Answer
given,
net charge = +2.00 μC
we know,
1 coulomb charge = 6.28 x 10¹⁸electrons
1 micro coulomb charge = 6.28 x 10¹⁸ x 10⁻⁶ electron
= 6.28 x 10¹² electrons
2.00 μC = 2 x 6.28 x 10¹² electrons
= 1.256 x 10¹³ electrons
since net charge is positive.
The number of protons should be 1.256 x 10¹³ more than electrons.
hence, +2.00 μC have 1.256 x 10¹³ more protons than electrons.
Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
