Suppose a spaceship is approaching the Earth at 0.25c and a message capsule is sent toward it at 0.25c relative to the Earth Randomized Variablesv = 0.25 cWhat is the ratio of the capsule’s speed, as measured on the spaceship, to the speed of light?μ/c =

Answer :

The ratio of the capsule’s speed, as measured on the spaceship, to the speed of light; μ/c 1/4.

Define the term speed of light?

  • One universal physical constant which is significant in many branches of physics is the speed of light in a vacuum, typically abbreviated as c.
  • The exact value of the speed of light, c, is 299,792,458 meters per second (approximately 300,000 kilometres per second; 186,000 miles per second; 671 million miles per hour).

For the stated question-

Consider sending a communication capsule to an incoming spacecraft at 0.25c relative to the Earth's randomized variablesv = 0.25 c.

Thus,

Let capsule’s speed is μ = 0.25 c.

Speed of light is c.

Then, ratio;

Capsule’s speed/Speed of light = 0.25 c/c

Capsule’s speed/Speed of light = 0.25

Capsule’s speed/Speed of light = 25/100

Capsule’s speed/Speed of light = 1/4

Thus, the ratio of capsule’s speed/Speed of light is found as 1/4.
