Given :

A map shows that a star is 25 light years away.

To Find :

If you get in a ship and travel to this star at 0.95c, How far will the ship need to travel to reach this star.

Solution :

We know, 1 light year in km is given by :

1 \ light \ years = 9.46 \times 10^{12}\  km

So, 25 light years is given by :

25 \ light \ years = 25 \times 9.46 \times 10^{12}\ km\\\\25 \ light \ years = 2.365 \times 10^{14} \ km

Hence, this is the required solution.

Are light waves longitudinal or transverse
Marysya12 [62]

Answer:

Transverse

Explanation:

There are two types of waves, according to the direction of their oscillation:

- Transverse waves: in a transverse wave, the direction of the oscillation is perpendicular to the direction of motion of the wave. Examples of transverse waves are electromagnetic waves

- Longitudinal waves: in a longitudinal wave, the direction of the oscillation is parallel to the direction of motion of the wave. Examples of longitudinal waves are sound waves.

Light waves corresponds to the visible part of the electromagnetic spectrum, which includes all the different types of electromagnetic waves (which consist of oscillations of electric and magnetic fields that are perpendicular to the direction of propagation of the wave): therefore, they are transverse waves.

An aerobatic airplane pilot experiences weightlessness as she passes over the top of a loop-the-loop maneuver. The acceleration
Debora [2.8K]

Answer:

The radius of the loop is  20.66 km

Explanation:

let the radius of the loop be r

mass of airplane is m

At the top, the pilot experiences two radial forces, which are

1) Gravitational force is  mg

2) Centrifugal forces mv²/r out of the center

When the pilot experiences no weight,

then, mg = mv²/r

r = v² / g

 = 450² / 9.8

 = 20.66 x 10³3

 = 20.66 km
