The lower the value of the coefficient of friction, the lower the resistance to sliding.
<u>Explanation:</u>
The coefficient of friction defines as directly proportionate with the resisting force, which is the frictional force. Hence, if there seems a decrease at coefficient of friction, then it is sure that the frictional force decreases.
We know that the frictional force on a body, is the product of coefficient of frictions and the normal forces acting on the body. Note that friction acts only, if a body is in contact, and it is of three types, static, kinetic and rolling.
Answer:
b. time-dependent magnetic field.
Answer:
Some more uses of ultrasonic are cleaning of difficult component, Echolocation etc. 1-Leakage detection in Pipelines--Infrasonic waves is used to detect the leakage in Pipelines etc. It shows the accurate point from where the tiny leakage occurs. It detect the signal through algorithm and separate it quickly.
