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.
