The correct answer to the question is D. Electromagnetic waves.

EXPLANATION:

As per the diagram, the radiations are emitted by sun is coming to earth.

The radiations coming from sun is electromagnetic in nature. It does not require any medium for its propagation. It travels a long distance in vacuum or space to reach earth.

It contains both electric field and magnetic field which are perpendicular to each other and also normal to the direction of propagation. The diagram shows that the wave is moving in the form of crests and troughs.

If we consider the wave nature of radiation, then it is one way of transportation of thermal energy from sun to earth which is known as radiation.

Hence, the arrows drawn in the figure is electromagnetic waves.

Mandarinka [93]

The period of the orbit would increase as well

Explanation:

We can answer this question by applying Kepler's third law, which states that:

"The square of the orbital period of a planet around the Sun is proportional to the cube of the semi-major axis of its orbit"

Mathematically,

\frac{T^2}{a^3}=const.

Where

T is the orbital period

a is the semi-major axis of the orbit

In this problem, the question asks what happens if the distance of the Earth from the Sun increases. Increasing this distance means increasing the semi-major axis of the orbit, a: but as we saw from the previous equation, the orbital period of the Earth is proportional to a, therefore as a increases, T increases as well.

Therefore, the period of the orbit would increase.

Lady_Fox [76]
Based on the given statement above, the correct answer would be FALSE. It is not true that range of motion is the distance an object can travel when separated from another object because range of motion or ROM is the distance--linear or angular--<span>that a movable object may normally travel while properly ATTACHED (not separated) to another. Hope this answer helps.</span>

The ratio of the focal length of a lens to it's diameter is the​
user100 [1]

Answer:

The f-ratio describes the relationship between the lens diameter and the focal length and is calculated by dividing the focal length by the diameter of the lens. For example, if a lens were to have a focal length of 50mm and a diameter of 10mm, then the f-ratio would be 50mm/10mm=5 or otherwise referred to as f5.
