Answer:
they meet at distance 25 feet
Explanation:
given data
acceleration of car = 8 ft/s²
truck speed = 10 ft/s
car initial speed u = 0
truck acceleration = 0
to find out
How far from the starting point will car overtake the truck
solution
we apply here equation of motion
s = ut + 0.5 ×a×t² .............1
here s is distance and a is acceleration and t is time u is initial speed
so truck distance
s = 10t + 0.5 ×0×t²
s = 10 t ...............2
and car distance
s = 0+ 0.5 ×8×t²
s = 4×t² ..........................3
so from equation 2 and 3
10 t = 4×t²
t = 2.5 s
so both meet at distance
s = 10 (t)
s = 10 ( 2.5 ) = 25 ft
so they meet at distance 25 feet

Explanation:
that was very good question thanks for asking.
Answer:
B: emits more light than a low luminosity star
Explanation:
Luminosity is an absolute measure of radiated electromagnetic power, the radiant power emitted by light scattering object. A star with large luminosity will have more measure of radiated electromagnetic power meaning it will emit more light than a low luminosity star. Luminosity has nothing to do with the color of star or distance.
Rest all options are wrong and only option b fits appropriate in the explaination above.
