Answer:

B. nuclear fusion

Explanation:

Atomic fusion is a process in which two or more lighter nuclei combine to form a heavier nucleus.

The mass of the single nucleus thus formed is lighter than the initial mass.

There is a difference in mass in the heavier nucleus thus formed. According to Einstein's mass-energy equation, the change in mass is equated towards energy.

The energy liberated in the process is called as thermo-nuclear energy.

As in the case of isotopes of hydrogen fuses to form helium, the nuclear reaction is given by relation

₁H³  +   ₁H² →   ₂He⁴   +   ₀n¹    +    energy

Thus, the nuclear reaction of hydrogen isotopes forming helium is nuclear fusion.

A large mass collides with a stationary, smaller mass. How will the masses behave if the collision is inelastic?
iragen [17]
Logically both masses will collide and well make a reaction. first of all depending on the small mass it will either merge or unite with the big mass or it will bounce away from it . if this happen it will make a reaction that will affect both masses. Hope this helps if it is incorrect please let me know :)

If the value of the electric field in an electromagnetic wave were doubled then
Norma-Jean [14]

Answer:

Electromagnetic wave are waves formed as a result of the oscillatory activities involving the electric and the magnetic field.

However in an Electromagnetic wave, the electric field and magnetic field carry equal amounts of energy and the magnitude of the electric field is directly proportional to the magnitude of the magnetic field. This direct proportionality gives rise to the speed of light being the constant between the two fields.

When the electric field is doubled then an equal action is to be set for the magnetic field so it doesn’t deviate from its main functions and characteristics.
