Answer:
b= 2.14 m
Explanation:
Given that
Weight of the board ,wt = 40 N
Wight of the first children , wt₁=500 N
Weight of the second children ,wt₂ = 350 N
The distance of the 500 N child from center ,a= 1.5 m
lets take distance of the 350 N child from center = b m
Now by taking the moment about the center of the board
We know that moment = Force x Perpendicular distance from the force
wt₁ x a = wt₂ x b
500 x 1.5 = 350 x b
b= 2.14 m
Therefore the distance of the 350 N weight child from the center is 2.14 m.
The atom is neutral (no electric charge)
Explanation:
An atom consists of:
- A nucleus, containing protons (positively charged) and neutrons (no electric charge)
- Electrons (negatively charged), orbiting around the nucleus
The charge of one proton is equal in magnitude (but opposite in sign) to that of an electron, and it is
Moreover, for a normal atom, the number of protons in the nucleus is equal to the number of electrons around it.
This means that for a normal atom, the net charge of it is zero, since the total charge of the protons balance that of the electrons.
So, the answer to the question is that the atom is neutral.

Answer:
The answer is "
"
Explanation:
The formula for velocity:
Sometimes arithmetic problems can be solved much more easily using the dimensional analysis approach. You focus on the units of the given information. Then, you manipulate them applying the laws of algebra where like units cancel, in order to end up with the unit of the unknown.
Given:
-50 nc/step
31 steps
Unknown: charge
Thus,
Charge = -50 nc/step * 31 steps =<em> -1550 nc</em>
