Fusion occurs when low mass nuclei, such as hydrogen collide and combine to form nuclei with greater masses.
Fusion could be the world's answer to clean unlimited amounts of energy.
Fusion is extremely difficult to contain and maintain here on earth.
Explanation:
Nuclear fusion is the combination of light atomic nuclei to form nuclei with greater mass.
The sun is powered by chain reaction involving fusion of light hydrogen nuclei to produce a more massive atom of helium.
- As with all nuclear reaction, mass is equivalent to energy. These reactions takes place place in the nucleus of an atom where nuclear forces are broken .
- it is known that nuclear fusion produces far more energy than fission reaction.
- It produces less radioactive wastes and could be the world's clean source of unlimited amount of energy.
- The major problem with fusion is that it is difficult to start and requires a a lot of energy to initiate.

Sry,I only know the answer of q2
Chlorine is a non metal because it is bad conductor of heat and sodium is a metal because it is good conductor of heat.
The 3 ways in which metal is different from non metal are given below:
1)metal are good conductor of heat but nonmetal are bad conductor of heat.
2)metals are malleable but non metal aren't malleable.
3)metals are generally ductile but non metal aren't ductile.
Hope it will helpyou!

Answer:
Explanation:
For elestic collision
v₁ = 
![v_2 = [tex]\frac{(m_2-m_1)u_2}{m_1+m_2} +\frac{2m_1u_1}{m_1+m_2}](https://tex.z-dn.net/?f=v_2%20%3D%20%5Btex%5D%5Cfrac%7B%28m_2-m_1%29u_2%7D%7Bm_1%2Bm_2%7D%20%2B%5Cfrac%7B2m_1u_1%7D%7Bm_1%2Bm_2%7D)
[/tex]
Here u₁ = 0 , u₂ = 22 m/s , m₁ = 77 kg , m₂ = .15 kg , v₁ and v₂ are velocity of goalie and puck after the collision.
v₁ = 0 + ( 2 x .15 x22 )/ 77.15
= .085 m / s
Velocity of goalie will be .085 m/s in the direction of original velocity of ball before collision.
v₂ = (.15 - 77)x 22 / 77.15 +0
= - 21.91 m /s
=Velocity of puck will be - 21.91 m /s in the direction opposite to original velocity of ball before collision.
