Answer:

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=t_{0}\sqrt {\frac {c^2 -v^2}{c^2}}

\Rightarrow t=4.3\sqrt {1-0.95^2}

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.

How does the mass of an object change the gravitational pull on two objects in a system? How does the distance between objects i
LuckyWell [14K]

Answer:The greater the mass, there greater then gravitational pull on their objects.

There greater the distance,the lower the gravitational pull between the object

Explanation:

Gravitational pull(force) is directly proportional to the products Of The masses. therefore if the mass increase,the gravitational pull(force) also increases.

Gravitational pull(force) is inversely proportional to distance.if the distance between the objects increases,the gravitational pull(force) decreases .
