Answer:
Explanation:
The oil drop remains stationary when the electric force on it and the gravitational force are balanced, so we have:
where
q is the charge of the oil drop
E is the electric field strength
m is the mass of the drop
g is the acceleration due to gravity
here we have
So the charge of the drop is
Answer:
By Applying pressure to the brakes
Explanation:
Driving cars through deep water that is more than 10cm can make the cars to float. Most modern cars are usually water- tight so they can start to float through water that is about 30cm deep, fast moving water is very powerful so one needs to be very careful when driving.
If the brakes are wet test them by pressing or tapping on them gently.
You can as well dry brakes by driving in low gear and applying pressure to the brakes.
The correct answer to this question is this one: "<span>B) 1 to 3√(3/2)^2 "

The fact that </span>Satellite A orbits the earth at a height 3.00 times the earth's radius and Satellite B orbits the earth at a height 2.00 times the earth's radius. The ratio of the of the period of Satellite B to the period of Satellite A is 1 :<span> 3√(3/2)^2

I think it blows vertically and horizontally cause wind can blow different directions
