Answer:
Explanation:
Work is force times distance in the direction of that force.
1)
W = 0.6(0.25 - 0.00) + 0.4(0.50 - 0.25) + 0.8(0.75 - 0.50)
W = 0.45 J
2)
W = 0.6(0.25 - 0.20) + 0.4(0.50 - 0.25) + 0.8(0.55 - 0.50)
W = 0.17 J
<span>When two or more identical capacitors (or resistors) are connected
in series across a potential difference, the potential difference divides
equally among them.
For example, if you have nine identical capacitors (or resistors) all
connected end-to-end like elephants in a circus parade, and you
connect the string to a source of 117 volts (either AC or DC), then
you will measure
(117v / 9) = 13 volts
across each unit in the string.</span>
Pe = m • g • h
= 100 • 9.8 • 20
= 19,600 or 1.96 x 10^4
