The sun's source of energy is know as nuclear fusion (means to fuse) this process has a small nuclei atoms that join together to form a large nucleus. The result of this process is released energy. The fusion of hydrogen into helium in the sun makes a large amount of energy and this is known as the sun's energy source.
The theories that scientist proposed about the source of the sun's energy was that the sun burned fuel to generate its energy and that gravity was causing the sun to shrink slowly and have its energy released. Also both of these theories were disproved.

Answer:
Explanation:
Force on a current carrying conductor in a magnetic field is given by the following expression
F = B i L where B is magnetic field perpendicular to wire or current , i is current and L is length of the wire.
Magnetic field of 1.5 x 10⁻⁵ T is making an angle of 60 degree with the wire so the component of field perpendicular to it
B = 1.5 X 10⁻⁵ Cos 30° = 1.3 x 10⁻⁵ T.
Force = BiL
= 1.3 X 10⁻⁵ X .4 X 1
= 5.2 X 10⁻⁶ N.
The direction of force can be found out from Fleming's left hand rule . It will be along downward direction.
Given the particle's acceleration is
with initial velocity
and starting at the origin, so that
you can compute the velocity and position functions by applying the fundamental theorem of calculus:
We have
• velocity at time <em>t</em> :
• position at time <em>t</em> :
Answer:no it is staying the same speed
Explanation:
They are similar to the earth. Not relative to the outer planets
