The answer is .
- A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.
- Kinetic energy comes in five forms: radiant, thermal, acoustic, electrical, and mechanical.
- The energy of a body in motion, or kinetic energy (KE), is essentially the energy of all moving objects. Along with potential energy, which is the stored energy present in objects at rest, it is one of the two primary types of energy.
- Explain that a moving object's mass and speed are two factors that impact the amount of kinetic energy it will possess.
Determine the escape speed for the rocket from the planet-satellite system:
The potential energy of the rocket due to Ganymede when it is on the surface of the Ganymede is,
The potential energy of the rocket due to Jupiter
when it is on the surface of the Ganymede is,
Here, R is a separation between Jupiter and Ganymede.
To escape from the surface of Ganymede potential energy of the rocket due to Jupiter and Ganymede is equal to the kinetic energy of the rocket.

Answer:
Part 1) Number of electrons in 1 liter of water equals
Part 2) Net charge of all the electrons equals
Explanation:
Since we know that the density of water is 1 kilogram per liter thus we infer that mass of 1 liter of water is 1 kilogram hence we need to find electron's in 1 kg of water.
Now since it is given that molar mass of water is 18.0 grams this means that 1 mole of water contains 18 grams of water.
Hence by ratio and proportion number of moles in 1 kg water equals
Now by definition of mole we know that 1 mole of any substance is Avagadro Number of particles.
Hence the no of molecules in 'n' moles of water equals
Now since it is given that each molecule has 10 electron's thus the total number of electrons in n' molecules equals
Part 2)
We know that charge of 1 electron equals the the charge of electrons in 'N' quantity equals
