Answer: Mechanical advantage is the measure of the force amplification achieved by using a tool , mechanical device or machine . The machine preserve the input power and supply trade off force. against movement to obtain a desired amplification in the output force .
Explanation: hope this helps
Answer:
Explanation:
At the corner of the square, the potential energy of interaction of other charges with the charge 2q is given by 
So
Also, since 
The initial energy of the system is given by;
Since 
, the final energy of the system is obtained by
From the law of conservation of energy, 
Therefore,
He must throw the device AWAY from the ship.
Since momentum is conserved, that move will give HIM an equal amount of momentum TOWARDS the ship.
