Answer:
a) increase
Explanation:
The frequency of sound produced due to vibration of a string is governed by the following formula
n = 1/2L√T/m ;
L is length of the string in vibration, T is tension in the string and m is mass of string per unit length.
So frequency is inversely proportional to length of the string. Hence shortning of length of string increases the frequency of vibration.
Answer: chemical property

Tectonic plates under the ground ,either go on top of each other or crash.
A phase of moon with more than half sunlit portion visible on the right
According to the Law of Conservation of Charge, the net
charge remains constant. If both things have different charges, upon contact,
they would share the charge equally. In this case, the total charge is -16μC.
The final charge for each ball would be -8 μC.
