<span>Carbon atom showing 6 protons as electro positive charge in its nuclei should have same no of -ve charged electrons , that is 6 electronns in its radii to make an atom of C as a neutral element , for that each element in its atomic state should have equal no of protons and electrons , the no of neutrons which has no electric charge and almost negligible weight does play significant role except contributes to isotopes of the given atom or an element, so C atom having 6 protons should have 6 electrons</span>
I would say A. because during the solar eclipse you cannot see the suns Photosphere at all, and the corona is the light that emits around the moon during the eclipse.
Answer:
a. Point A
b. 20 V
c. 100 J
Explanation:
a. Point A is at a higher potential because there is a positive sign in front of its magnitude. Since it is a positive integral value, and has a higher magnitude than point B which is at -4, point A is thus at a higher potential than point B.
b. The potential difference between the two points ΔV = A - B
= +16 V - (-4 V)
= +16 V + 4 V
= + 20 V
c. The work done, W in moving a charge Q across a potential difference ΔV is W = QΔV
So, since Q = 5 C and ΔV = + 20 V
W = QΔV
= 5 C × (+ 20 V)
= 100 J
Answer:
Newton's Cradle experiment perfectly demonstrates the law of conservation of momentum which states that in a closed system, momentum before the collision is equal to momentum after the collision of the system.
As the first ball swings in the air, it gains momentum. When it strikes the second ball, it loses momentum and second ball gains equal amount of momentum. The second ball transfers the momentum to third, then fourth and till the last. The last ball when gains the same momentum swings up in the air. This continues. This experiment is done in drag free condition. This means there is no loss of momentum or opposing forces present.
Answer:
The capacity of doing work is called energy.
its forms are :
1. mechanical energy
2.potential energy
3. kinetics energy
4. heat energy
5. light energy
6.sound energy
7. wind energy .etc.
