D determined by its temperature
Answer:
Explanation:
velocity of the Escalators is given as 6 ft/s
now we know that Jane steps on parallel escalator after t = 5 s
so distance moved by John in same time interval is given as
now John and Jane will move towards each other with relative speed
Then will approach towards each other with this relative speed and meet after t = 15 s
so the distance moved by them
so total length of the escalators is given as
light, water, carbon dioxide
Explanation:
c02 , h20 and light
Answer:
The plasma state would have the least potential energy and the greatest kinetic energy.
Explanation:
i just took the test and i go it right
Answer:
2 m/s²
Explanation:
Acceleration is change in velocity over change in time.
a = Δv / Δt
a = (18 m/s − 10 m/s) / 4 s
a = 2 m/s²
