Answer:
The speed is 
Explanation:
Electric field magnitude (E) and electric force magnitude (F) are related by the equation

with q the charge of the proton (
). Because between parallel plates electric field is almost constant, electric force is constant too:

because electric force is constant, then by Newton's second law acceleration (a) is constant too, it is:

with m the mass of the proton (
):

Now with this constant acceleration we can use the kinematic equation

with v the final speed,
the initial velocity that is zero (because proton starts at rest) and d is the distance between the plates, so:

This would be an illustration of Newton's first law of motion. Law of inertia, an object moving at constant velocity will keep moving at constant velocity until a force is acted upon it. Inertia is the tendency of an object to keep moving in a particular direction resisting to change, unless a force acts upon the object.
Answer:
if u are caught by the jews u die
Explanation:
Answer: As per the question, a ray of light is incident on a surface and it is partly reflected and refracted. The incident light is an unpolarised light. The reflected light is partially polarised.
If the angle of incidence becomes equal to the Brester angle (polarising angle), then the reflected light is completely plane polarised.
