Answer:
1. Direction of B is parallel to V
2. Magnetic field is most uniform between the flat, parallel magnetic poles of a c-shaped magnet
3. Doubling B would double the magnitude of the force on the proton
4. Magnetic field is strongest near the north and south poles
5. The initial direction of the proton is toward the right of the screen. The field deflects the proton toward the top of the screen
6. Assume that you are viewing the diagram on a flat computer screen. Perpendicular to the screen, pointing toward you.
7. A stationary point charge doesn’t generate a magnetic field in the space around it.
8. Proton enters magnetic field at a speed of 7.8 x 10^4, charge of proton equal to 1.6 x 10^-19 is 2.6 x 10^-14 N
9. A few times every million years
10. Magnitude |q|vB directed towards bottom of screen

Answer:
A spinning electron produces a magnetic field.
Explains the fine structure of Hydrogen lines.
It protects us by keeping ultraviolet out and make sure everything lives
Explanation:
The direction of electric field is always tangential to field lines. However, free charged particles do not necessarily move alone the field lines. Curved field lines means that there is a continuous change of force on the charge and thus, its direction of acceleration would change accordingly. Moreover, if the charge is negative it is bound to move opposite to the field direction. Hence, we can say that although electric field is tangent to electric field lines, free charged particles do not necessarily move alone the field lines.
the answer is B
the size shape or state of matter changes
because if the shape and size are changing it’s still the same thing.
for example
water to ice
