After my ythorough researching, the orbital velocity of the Earth compare to the Mercury is relative to each other. In addition, Mercury orbits the Sun and it is within the Earth's orbit as its lesser or inferior. The correct answer to the following given statement above is relative to each other.
Answer:
Acceleration of proton will be
Explanation:
We have given surface charge density of an infinite charged plate 
Electric field due to infinite sheet charge is given by 
Charge in proton is given by 
So force on proton 
Mass of proton 
According to newtons second law force F = mass × acceleration
So 

Answer:
434.0 V/m
Explanation:
The power output of the laser is:

while the radius of the beam is

so the cross-sectional area is

So the intensity of the laser beam is

The intensity of a laser beam is related to the magnitude of the electric field by

where
c is the speed of light
is the vacuum permittivity
Solving the formula for E, we find

Answer:
Objective Lenses: Usually you find 3 or 4 objective lenses on a microscope. They almost always consist of 4x, 10x, 40x and 100x powers, when coupled with a 10x (most common) eyepiece lens, total magnification is 40x (4x times 10x) 100x, 400x and 1000x
Explanation:
Objective lenses come in various magnification powers, with the most common being 4x, 10x, 40x, and 100x, also known as scanning, low power, high power and typically oil immersion objectives, respectively
Answer:
2000 mili ampere
Explanation:
1 ampere is = to 1000 miliampere so 2 x 1000 is equal to 2000 miliampere
