Our milky way galaxy is 100,000 ly in diameter. a spaceship crossing the galaxy measures the galaxy's diameter to be a mere 1 ly. what is the speed of the spaceship relative to the galaxy? and how long is the crossing time as measured in the galaxy's reference frame?

t= 100000.000005 years

Explanation:

Our Milky Way galaxy is 100,000 ly in diameter.

the galaxy's diameter to be a mere 1 ly.

We know that

L= 1 ly

L_0= 100,000 ly

v= 0.99999999995 c

so time t=

t= 100000.000005 years

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right

a.   mass number from atomic number
