The sun is a star. The sar is a
ball of hot gases containing different kinds of elements at different cores. It
has a very high temperature that radiates all throughout the Milky Way galaxy.
The sun has four main parts; the core, photosphere, chromospheres and corona.
The outer core of a star located at the chromospheres contains mostly of
hydrogen. Inside the hydrogen is helium then carbon, oxygen, neon, magnesium
silicon and the inert gas. When a star releases energy it is due to the
thermonuclear fusion of hydrogen into helium. So the answer is letter C.

Answer:
Explanation:
The collision is inelastic and can be described by the Principle of Momentum Conservation:
The speed after the collision is:
Answer:
2.59m/s
Explanation:
Using the equation of motion
v = u+at
v is the final velocity = 35ms
u is the initially velocity = 9m/s
t is the time = 13.5s
a is the acceleration
Substitute into the formula
35 = 0+13.5a
a = 35/13.5
a = 2.59m/s²
Hence the acceleration of the motorcycle is 2.59m/s
