Answer: The speed necessary for the electron to have this energy is 466462 m/s
Explanation:
Kinetic energy is the energy posessed by an object by virtue of its motion.
K.E= kinetic energy =
m= mass of an electron =
v= velocity of object = ?
Putting in the values in the equation:
The speed necessary for the electron to have this energy is 466462 m/s
The work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.
Given the data in the question:
- Mass raised;
- Distance covered;
Work done;
First we calculate the force used to raise the mass to the given distance.
Since the movement was vertical, the force must over come the mass and the pull of gravity ( ).
Using Newton's second law of Motion;
We substitute our values into the equation
Now, we determine the work done by Nick.
Work done is simply the energy transferred from one store to another.
It is expressed as;
So we substitute our values into the equation
Therefore, the work done by Nick as he raises the given mass over the given distance is approximately 2 Joules.
