Answer: Electromagnetic waves can transfer energy through empty space.

Explanation:

Electromagnetic waves are formed when an electric field comes in contact with a magnetic field. The electric field and magnetic field of an electromagnetic wave are perpendicular to each other. They are also perpendicular to the direction of the wave.

Electromagnetic waves travel with speed of light in vacuum.

Electromagnetic wave does not need a medium to propagate or travel from one place to another. Electromagnetic waves are 'transverse' waves which means that they are measured by their amplitude and wavelength.

Electromagnetic waves do not lose energy when they travel and thus can travel far from its source.

klemol [59]

Answer:

32.5 ms⁻¹

Explanation:

<em><u>Theory </u></em>

<u> The law of conservation of linear momentum </u>

The sum of linear momentum of a system under no external force remains constant.

In this scenario although different forces act on two vehicles by each other when we  consider the total system of two cars no external unbalance force act on them. So we can apply this law.

As law says,

The sum of linear momentum before collision = The sum of linear momentum after collision.

Momentum = mass × velocity

1000×40+3000×35 = 1000×v + 3000×37.5

where v = velocity of the red car after the cash

v = 32.5 ms⁻¹
