Answer:
Chain reaction is possible by neutron
Explanation:
Nuclear reaction is mainly two types,
⇒ Nuclear Fission : heavy atom split into two light atom.
Ex. Uranium, thorium
⇒ Nuclear fusion : lighter atom combine together
Ex. Hydrogen to helium
In fusion reaction the large amount of energy is produced as compare to fission reaction.
Sun gets brighter by fusion reaction.
In case of uranium fission reaction is possible by colliding neutron.
The guy below is wrong!
F=ma
Where force = mass x acceleration
We dont have acceleration, a= change in velocity divided by the time taken.
a = v (final velocity) - u (initial) / t
a us 8-0 (at rest means u was 0) / 20 = 0.4
Using F=ma
F= mass x acceleration
F= 4 x 0.4
F=1.6 N
Answer:
It won't stop
Explanation:
If it is a frictionless surface ....the block will not stop until another force acts on it
