23 m
Explanation:
the picture attached shows the explanation
Answer:
The answer is 4th choice. Down with a speed less than v.
Explanation:
The momentum of the person and the balloon need to cancel each other out. Momentum formula of the balloon is as following:
At the moment of t=0, the person and the balloon has the 0 speed.
When the person starts to climb on a balloon, balloon need to cancel this momentum out. We know that the balloon is more heavier than the person. So balloon need to go down with the speed of less than v.
The quantum mechanics theory
An example helps clarify the difference between an analysis, a deter- mination and ... departments analyze samples of water to determine the concentration of ... moles of Cu2+, and cylinder 2 contains 20 mL, or 2.0 × 10.
Answer:
The plan would not be successful
Explanation:
Radar ranging is not suitable for this plan because of the challenges that associate with the implementation of radar ranging. The Radar is a detection system that uses radio waves to determine the range, angle, or velocity of objects. The distance of these kuiper belts to the earth is enormously large, as soon as the signal is sent, it begins to spread out and the larger the distance the more spread out the signal would have been before getting to its destination, the more the echo that is generated resulting in a very poor signal strength.
