Yes , increased tension suggests increased molecular attraction between the molecules of the ropes which affect the increase in the speed of wave.
Higher Power Efficiency and Eliminates Risk of Compressor Breakdown
Main Answer:
Given speed of spaceship v = 0.8c = 0.8 * 3 x 10^8 m/s
Speed of spaceship v = 2.4 x 10^8 m/s
Distance need to be travelled d = 4.3 light years
we know that 1 light year = 9.461 x 10^15 m
Distance need to be travelled d = 4.3 x 9.461 x 10^15
d = 40.6823 x 10^15 m
Time taken for the trip would elapse on a clock on board the spaceship
t = distance/ velocity
t = 40.6823 x 10^15 / 2.4 x 10^8
t = 16.95 x 10^7 sec
t = 4.71 x 10^4 hours
Explanation:
What is light year?
Light year is defined as the distance travelled by the light in one year. In a year, light travels through 300000 km per sec in the interstellar space.
