This is easily explained saying that the frictional force between the books and the paper isn't big enough to produce a displacement in the books. The displacement in the books doesn't happen because the frictional force between the books and the surface they are standing on is bigger than the paper's one.
Answer: 12,600,000Cm
Explanation:
From the data's;
Charges(q) = 1.8 PC equal to 1.8 x 10^¹²C
Distance = 7 micrometer, is equal to 0.0000070m
From the equation of electric dipole moment, p= q x d, where q= charge, d=distance and p is the dipole moment.
Then we have 1.8x10^¹² x 0.0000070= 12,600,000Cm
NB: The charges are identical.
Answer:c
Explanation:
the rate of reaction increases as temperature increases
Answer:
Explanation:
Given
Force 
one at an angle of
East of North and another at
West of North
Net Force is in North Direction

Forces in horizontal direction will cancel out each other
thus Work done will be by north direction forces

here 

The answer is might be 352
