Answer:
That's almost the true
Explanation:
it does not happen all the time
Answer: The initial force is reduced a factor 1/4 when the separation between charge is doubled
Explanation: As it well known the electric force between two charges is given by:
Finitial=k*q1*q2/d^2 where d is the distance between charges and k is a constant
if the distance is doubled this means 2*dinitial thus the new force is equal to F initial* 1/4
Answer:
Radians
Explanation:
The angular speed is a measure of the rotation speed of a body. It is defined as the angle rotated by a unit of time. Thus, It refers to the angular displacement per unit time and is designated by the Greek letter
. Its unit in the International System is radian per second (rad / s).
Answer:
0 N.
Explanation:
Force: This can be defined as the product of mass and the acceleration of the body. The S.I unit of force is Newton (N).
The expression of net force when both force act in the different direction is given as
F' = W-F ........................ Equation 1
Where F' = Net force on the bag, W = gravitational force on the bag, F = Force acting upward on the bag
Given: W = 18 N, F = 18 N.
Substitute into equation 1
F' = 18-18
F' = 0 N.
Hence the net force = 0 N.
Answer:
1) Skid
2)<u> </u>Rocking
3) Oversteer situation
4) Controlled breaking
5) Overdriving headlights
6) Hydroplaning
7) Understeer situation
Explanation:
1) A <u>skid</u> results when a vehicle loses part or all of its grip on the road
2)<u> Rocking</u> is a technique that can be applied when trying to move your vehicle out of deep snow
3) The action of vehicle's rear end sliding out to a side is called an <u>oversteer situation</u>
4) <u>Controlled breaking</u> is a technique of reducing your speed as quick as possible while maintaining control of your vehicle
5) Driving at a speed where the stopping distance of your vehicle is longer than the distance you can see with your headlights is called <u>overdriving headlights</u>
6) <u>Hydroplaning</u> occurs when a tire loses road surface contact and rises on top of water
7) It is an <u>understeer situation</u> when your front tires begin to plow and your vehicle is not responding or not responding as quickly as it should, to a steering point
