Answer:
neon light
all the others are natural phenomenon
- Initial velocity (u) = 10 m/s
- Final velocity (v) = 22 m/s
- Time (t) = 12 s
- Mass (m) = 200 Kg
- Let the acceleration be a.
- By using the equation of motion,
v = u + at, we have
- 22 m/s = 10 m/s + 12 s × a
- or, 22m/s - 10 m/s = 12 s × a
- or, 12 m/s = 12 s × a
- or, a = 1 m/s^2
- Let the force be F.
- We know, F = ma
- Therefore, the force on the accelerated object (F)
- = ma
- = (200 × 1) N
- = 200 N

Hope you could understand.
If you have any query, feel free to ask.
Potential energy is stored energy. For example, if a bowling ball is on top of a giant hill, we say it has potential energy because it has the potential to do work which is to roll down the hill.
Kinetic energy is the energy of movement so once that ball rolls down that hill, that potential energy is converted to kinetic energy.
Answer:
The number of atoms are 
.
Explanation:
Given that,
Diameter 
Distance = 2.60 cm
We calculate the number of atoms
Using formula of numbers of atoms
Hence, The number of atoms are .
