Answer:
44.4 m/s
Explanation:
d = 80 m, t = 1.8 s, find v
d = v*t
v = d/t = 80/1.8 = 44.4 m/s
Gravitational potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy.
The water starts up (potential) and flows down (kinetic), the flowing water turns a big wheel (mechanical) which creates electricity (electrical).
A. An electron has far less mass than either a proton or neutron.
<u>Answer;</u>
= 20 ohms
<u>Explanation;</u>
- According to the Ohm's law, the current through a conductor is directly proportional to the potential difference if other environment conditions are kept constant.
Therefore; I α V
Hence; V = IR, where R is the constant, called the resistance
Therefore; R = V/I
R = 6.0 /0.3
<u> = 20 Ohms</u>
