The work done by the electric force to move a 1 c charge from a to b is
<em>(the voltage at 'b' compared to 'a') volts .</em>
<em></em>
That's because "volt" means "Joule per Coulomb" .
Thomson used a beam of negatively charged particles.
Answer:
a = 0.8 [m/s²]
Explanation:
To solve this problem we must use Newton's second law which tells us that the resulting force on a body is equal to the product of mass by acceleration, in this way we come to the following equation:
∑F = m*a
where:
F = forces applied [N]
m = mass = 1000 [kg]
a = acceleration [m/s²]
Now using Newton's second law.
![1200 - 400 = 1000*a\\800 = 1000 *a\\a=0.8[m/s^{2} ]](https://tex.z-dn.net/?f=1200%20-%20400%20%3D%201000%2Aa%5C%5C800%20%3D%201000%20%2Aa%5C%5Ca%3D0.8%5Bm%2Fs%5E%7B2%7D%20%5D)

Explanation:
The battery is a store of internal energy (shown as chemical energy). The energy is transferred through the wires to the lamp, which then transfers the energy to the surroundings as light. These are the useful energy transfers - we use electric lamps to light up our rooms.
