Answer:
B. 832 m/s
Explanation:
(1/2) (0.015) v^2 = (3/2) (1.5) (8.31) (278)
0.0075 v^2 = 5197.905
v^2 = 693054
v = 832.49
Answer:
ABSOLUTE MAGNITUDE, C
Explanation:
Absolute magnitude is how bright the star is from a distance of 10 parsecs. Apparent magnitude is how bright the star appears from Earth, which can vary, because some stars may be farther or closer away. Age and size are not very accurate either. For example, at the end of their lifetimes, very big start may explode in a violent and bright supernova, and outshine the stars near them. As for size, as many stars several times smaller than the sun shine much brighter than it, making it inaccurate.

Answer:
1 km = 1000 m
Explanation:
1 km = 1000 m
For uniform velocity motion; time taken = distance covered/average speed (t = d/v)
t = 1000/850 = 1.18 seconds
