pitch increased
The surface tension of water is increased for salted water.Sodium chloride increase the surface tension of water.
increase the length of the string means decrease the tension in the string, therefore as the tension decreases the frequency will drop due to loosen of the string.

If the speed increased and the wavelngth stayed the same then the frequency would have to increase. Because Speed=Frequency*Wavelength Hope that helps
Because of centrifugal force tension on both side will be increased but at the same time normal reaction force in between belt and pulley surface will goes down so frictional tension will be decrease and ultimately power transmission efficiency will decrease.
Sodium chloride increase the surface tension of water and methanol decrease the surface tension of water.
front and back tension plays significance role in rolling. front tension increases the forward slip and back tension will do reverse. with increase in front tension roll force required to reduce the thickness will decrease.
Wht do we has to decrease the surface tension for clean the clothes
For most liquids, an increase in pH results in decreased surface tension. This has been attributed to lower attraction force between molecules when pH rises.
