Answer:

Explanation:
v = Speed of electron =
(generally the order of magnitude is 6)
m = Mass of electron = 
Work done would be done by

The work required to stop the electron is 
You find net charge by subtracting the number of electrons from the number of protons (since protons are positive and electrons are negative). 9 - 10 = -1
Answer:
Heliocentrism, a cosmological model in which the Sun is assumed to lie at or near a central point (e.g., of the solar system or of the universe) while the Earth and other bodies revolve around it.
Explanation:
Answer:
Output voltage is 1.92 volts.
Explanation:
Given that,
Number of turns in primary coil, 
Number of turns in secondary coil, 
Input voltage, 
We need to find the voltage output of a transformer used for rechargeable flashlight batteries. For a transformer, the number of turns and the voltage ratio is given by :

So, the output voltage is 1.92 volts.
