The speed of the spaceship relative to the galaxy is 0.99999995c.
A light-year measures distance rather than time (as the name might imply). A light-year is a distance a light beam travels in one year on Earth, which is roughly 6 trillion miles (9.7 trillion kilometers). One light-year equals 5,878,625,370,000 miles. Light moves at a speed of 670,616,629 mph (1,079,252,849 km/h) in a vacuum.We multiply this speed by the number of hours in a year to calculate the distance of a light-year (8,766).
The Milky way galaxy is 100,000 light years in diameter.
The galaxy's diameter is a mere 1. 0 ly.
We know that ;
L = 1 light year
L₀ = 100,000 light year
Therefore, the speed of the spaceship relative to the galaxy is 0.99999995c.

Formula: Ca=Vt^2/r
centripetal acceleration(Ca)= ?
tangential speed(Vt)= 2.8m/s
Radius(r)=2m
Substitute: Ca=2.8^2/2
Ca=3.92m/s^2
Answer:
The percentage of mass recover from recrystallization = 24.69 %
Explanation:
Given that
Initial mass of crude acetanilide = 166 gm
The mass after recrystallization = 125 gm
The mass recover from recrystallization= 166 - 125 gm
The mass recover from recrystallization= 41 gm
The percentage of mass recover from recrystallization can be find as
The percentage of mass recover from recrystallization = 24.69 %
Answer:
A) After the Space Age ended, many people moved to other states and the economy began to decline.
Explanation:
After the space age ended, businesses slumped, when the space shuttle program ended those made redundant could not be re absorbed due to a lack of follow-on by NASA. The 2008 recession also had impacted businesses in the area. As such many moved to other states, which had the effect of a brain drain.
After Apollo, in the late 70's, there was a similar decline of economic activities as workers were laid off and where finding it hard to sell off their properties as the real estate prices where low.
