C) In the absence of an unbalanced force, an object at rest will stay at rest and an object in motion will stay in motion.
hope this helps and have a great day :)
Answer:
acceleration=(v final-vinitial)/time
a=(vf-vi)/t
2=(30-10)/t
2=20/t
t=20/2=10 seconds
distance=v0t+at²/2
d=10 x 10+ 2x 10²/2=100+100= 200 m
Explanation:
Answer:
to prevent the derailing of the train due to thermal expansion.
I think is a high-pressure system because it is only in one particular area.
D. since the star would be larger than the sun, having more mass, its gravitational pull would be stronger thus pulling the planets into it. hope that helped!
