Answer:

Option (1), (3) and (4) are correct.

Explanation:

When the oscillating electri and magnetic field interacts perpendicularly to each other, the electromagnetic radiations are produced. The electromagnetic radiations propagates in the perpendicular direction of both electric and magnetic field vectors.

For example, gamma rays, X rays, ultra violet rays, visible radiations, infrared rays, micro waves and radio waves.

Electromagnetic radiations do not require any medium for their propagation.

They do not carry mass, they carry energy only.

Dominik [7]
A = delta v over delta t delta v is calculated with final velocity less initial velocity then delta v is equals to 20 - 0 that is 20m/s and to calculate delta t is like delta v is final time less initial time as initial time always is 0 the delta t is equals to 10s then a = 20/10 then acceleration is 10m/s^2 (remember that is squared)
