Astronomy is the study of stars and planets.
Answer:
v = 4.08 m/s
Explanation:
conservation of momentum
Let m = 1.39e4 kg
m(6.75) + m(1.41) = (m + m)v
m(6.75) + m(1.41) = 2mv
6.75 + 1.41 = 2v
8.16 = 2v
v = 4.08 m/s
Answer:
Stability
Explanation:
The Stability of an air mass is greatly affected by trajectory that air mass follows whether the trajectory is cylonic or anticyclonic.
Answer:
3 s
Explanation:
s = 2t^2 - 3t
s = 9 m
(t - 3)(2t + 3) = 0
time cannot be negative, so t = 3 s
Thus, the object takes 3 second to move 9 m.
Answer:
All three pendulum will attain same velocity
Explanation:
All three pendulum will attain same velocity irrespective of their mass difference in isolated system (means where air drag are negligible) and at same length
As you know when velocity is calculated we can not take mass into account.
