Answer:
Water droplets could obtain charges thru contact with other drops.
Then if two similar drops (both positively charged) came in contact
charge could be transferred because one side of the drop would be positive and one side of the other would be negative by induction.
Several Physics Labs have built experiments called "Kelvins Thunderstorm"
where objects found in the home could be used to build a charge generator that can generate several thousand volts from falling water droplets.
Lightning usually occurs because of the very large potential that can build
because of charge differences between overhead clouds and the induced charge that will then follow in the ground. Mountain climbers know that it's time to look for safer ground when sparks start to jump from the ropes.
Heat, light, motion, sound can all be produced in a chemical reaction and could be considered forms of energy: thermal energy, electromagnetic energy, kinetic energy, and sound

D
Answer:
B) 2g
Explanation:
<u>Given the following data;</u>
Velocity, v = 14m/s
Radius, r = 10m
To find the centripetal acceleration;
Substituting into the equation, we have;
Acceleration, a = 19.6m/s²
In terms of acceleration due to gravity, g = 9.8m/s²
We would divide by g;
Acceleration, a = 19.6/9.8 = 2
Hence, centripetal acceleration = 2g
Therefore, the rider's centripetal acceleration in terms of g, the acceleration due to gravity is 2g.
