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.
Answer:
Its the sum of the potential energy and the kinetic energy
Answer:
They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw. simple machines.
We calculate the coordinates at t₁ = 9 min and t₂ = 10 min, since the 10th minute is between t₁ and t₂.
As it leaves from rest, it means that the initial speed is zero
t₁=9 min=540 s
t₂=10 min=600 s
x₁=at₁²/2=8*540²/2=4*291600=1166400 m
x₂=at₂²/2=8*600²/2=4*360000=1440000 m
Δx=x₂-x₁=1440000-1166400=273600 m represents the distance traveled by the car in the 10th minute of travel
