Answer:
A - They are both electromagnetic waves.
Explanation:
Electromagnetic waves are waves consisting of periodic oscillations of electric and magnetic fields, that vibrate in a plane perpendicular to the direction of propagation of the wave (for this reason, they are said to be "transverse waves").
Electromagnetic waves, unlike mechanical waves, can travel through a vacuum, and do not need a medium to propagate. Their speed in a vacuum is a constant and it is called speed of light ().
Electromagnetic waves are classified, depending on their wavelength and frequency, into 7 different types - together they form the electromagnetic spectrum. The 7 types, listed from shortest to longest wavelength, are:
gamma rays
X-rays
ultraviolet radiation
visible light
infrared radiation
microwaves
radio waves
All these waves, despite having different properties, are all electromagnetic waves -so we see that both radio waves and gamma rays belong to this type of waves.
Answer: ≈ 323 m
using Newton's 2nd law, we have:
F = ma
⇒ 5 = 6.a
⇔ a = 5/6 (m/s²)
the work done in 25s is ≈ 323 (m)
