Answer:
No
Explanation:
From the analogy of the problem we are made to know that "a man standing on the earth can exert the same force with his legs as when he is standing on the moon".
This force he is exerting is due to his weight. If he can have the same weight on the earth and moon, therefore:
weight = mass x acceleration due gravity
His mass and acceleration due to gravity on both terrestrial bodies are the same.
So, his jump height will be the same on earth and on the moon.
In summary, we have been shown that his mass and the acceleration due to gravity on both planets are the same, therefore, his weight will also be the same. His jump height will also be same.
I believe it would double the strength of the electromagnet as well
Hope this helps!
Answer:
-22.5 m/s
Explanation:
= Mass of squid = 1.5 kg
= Mass of water ejected = 0.14 kg
= Velocity of squid = 0.4 m/s
= Velocity of squid after ejection = 2.5 m/s
v = Velocity of water ejection
In this system the momentum is conserved

The velocity of the water ejection relative to the squid is
-20+(-2.5) = -22.5 m/s
The negative sign indicates the opposite direction to the direction of the squid.
