Aspaceship travels at a speed of 0.95c to the nearest star, alpha centauri, 4.3 light years (ly) away. how long does the trip take from the point of view of the passengers on the ship? a. 1.4 ly b. 1.0 ly c. 4.5 ly d. 14 ly e. 0.44

A  1.4ly

Explanation:

speed v= 0.95c c= speed of light distance t₀=4.3ly

As per the time dilation priciple we know that

t=1.4 ly

therefore, it will take 1.4ly for the trip from the point of view of passenger on ship. ly here is light year.

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.
