Answer:
A star uses fusion as an energy source by building larger atoms from smaller atoms.
Explanation:
Nuclear fission and fusion are two processes at which an atomic nucleus is changed to produce energy. Fission is the process splitting heavy atomic into lighter atomic nuclei.
So, fusion is the combination of smaller atoms to form larger atoms and star uses this as source of energy.
Fusion is the process at which light atomic nuclei are merged or fused together to form heavier nuclei.
The energy source for all stars is nuclear fusion. In a nuclear fusion reaction, the nuclei of two atoms combine to create a new atom. Most commonly, in the core of a star, two hydrogen atoms fuse to become a helium atom.

Answer:
towards right
towards left
Explanation:
= Mass of skater = 56 kg
= Mass of ball = 5 kg
v = Final velocity of ball = 7 m/s
u = Initial velocity of ball = 0
s = Distance the ball moved in the hand of the skater = 1 m
Moving left is considered and moving right is considered positive.
From kinematic equations of motion we have
So, the ball will move towards right with a magnitude of acceleration .
The force on the ball will be
The force on the ball is 
The reaction force on the skater will be equal to the force on the ball but will have opposite direction.
So, the skater will move towards left with a magnitude of acceleration 
If it were not for these two men, we might not have come to understand microorganisms. These men are named Anton Van Leeuenhook and Robert Hooke.
