Answer:
Acceleration, 
Explanation:
It is given that,
Side of the square plate, l = 1 m
Charge on the square plate, 
Position of a proton, x = 1 cm
The electric field due to a parallel plate is given by :

Electric force is given by :
F = q E

e is the charge on electron
The acceleration of the proton can be calculated as :

m is the mass of proton



So, the acceleration of the proton is
. Hence, this is the required solution.
Answer:
yes
Explanation:
Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles.
its important so we can learn things about the species
Answer:
Orbital period, T = 1.00074 years
Explanation:
It is given that,
Orbital radius of a solar system planet, 
The orbital period of the planet can be calculated using third law of Kepler's. It is as follows :

M is the mass of the sun

T = 31559467.6761 s
T = 1.00074 years
So, a solar-system planet that has an orbital radius of 4 AU would have an orbital period of about 1.00074 years.
