Actually, the real reason it appears yellow-white is because of the temperature of the star. the stars that are hotter tend to be more blue and the stars that aren’t as hot tend to be more red/orange/yellow.
Answer: Magnetic Fields
Explanation: A Compass works by detecting the earth's magnetic fields. The earth has a iron core that is part liquid and part solid crystal due to gravitational pressure.

Answer:
The charged particle will follow a circular path.
Explanation:
The magnetic force exerted on the charged particle due to the magnetic field is given by:
where
q is the charge
v is the velocity of the particle
B is the magnetic field
is the angle between v and B
In this problem, the velocity is perpendicular to the magnetic field, so and the force is simply
Moreover, the force is perpendicular to both B and v, according to the right-hand rule. Therefore, we have:
- a force that is always perpendicular to the velocity, v
- a force which is constant in magnitude (because the magnitude of v or B does not change)
--> this means that the force acts as a centripetal force, so it will keep the charged particle in a uniform circular motion. So, the correct answer is
The charged particle will follow a circular path.
I would say the expandable one
I’m not sure if I’m right, if I am I hope this helped you, have a wonderful day!
