Answer: Fusion
Explanation:
Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.
Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.
Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

Hope its helps u
if wrong then sry
Answer:
The total momentum after the collision is 1 kg-m/s.
Explanation:
We have,
Mass of a steel sphere is 0.5 kg
It is travelling with a speed of 2 m/s
It collides with an identical sphere at rest.
The law of conservation of momentum states that the initial momentum is equal to the final momentum for an isolated system. Here, initial momentum is :
So, the total momentum after the collision is 1 kg-m/s.
Answer:
frequency = 104.80 Hz
wavelength = 0.567 m
frequency = 104.80 Hz
wavelength = 3.27 m
Explanation:
given data
mass m = 9.4 g = 9.4 × m
length L = 85 cm = 0.85 m
tension T = 39 N
to find out
frequency and wavelength
solution
first we find frequency for second overtone
f = 3 /2L × √(T/μ) .............1
put here all value and
here μ = m/L = 9.4 × / 0.85 = 1.10588 ×
kg/m
f = 3 /2(0.85) × √(39/1.10588 ×)
f = 104.80 Hz
and
wavelength is 2L/3
wavelength = 2(0.85) / 3
wavelength = 0.567 m
and
frequency = 104.80 Hz
and
wavelength by speed of sound i.e 343 m/s
wavelength = speed / f
wavelength = 343 / 104.80
wavelength = 3.27 m
