Answer:
10,000 eV
Explanation:
Due to the law of conservation of energy, the kinetic energy of the electron at the end of its path is equal to its initial electric potential energy, given by:
where
q is the electron charge
is the potential difference
Here we have:
is the electron's charged
is the potential difference
Substituting into the formula, we have
Answer:
a.
b.
Explanation:
The computation is shown below:
data provided in the question
The initial angular velocity = 0 rev/s,
f = Final angular velocity = = 382000 rpm i.e =
= 6,366.67
And time = t = 3.0s
Based on the above information
a. For angular acceleration of drill
b. For the number of revolutions
We simply applied the above formulas for determining each parts
