Answer:
1 ml/second is a small flow
Explanation:
The vibration is thermal energy ("heat" energy which every object possesses).
The second one is kinetic energy ("motion" energy of a massive object)
Answer:
I would say that is false. Science can only be perfect after at least some sort of scientific communication and interaction.
F = m a
360 = 270 x a
1.3 = a
Y - yo = Vo*t - g * (t^2) / 2
Vo = - 9.0 m/s
t = 0.50 s
=> y - yo = -9.0 m/s * 0.5 s - 9.8 m/s^2 * (0.5s)^2 / 2 = - 4.5m - 1.225m = - 5.725 m.
Answer: option c) - 5.7
