If a vibrating string is made shorter (i. e., by holding your finger on it), what effect does this have on the frequency of vibration and on the pitch? 1. both decrease. 2. no effect 3. both increase. 4. the frequency decreases; the pitch decreases. 5. the frequency increases; the pitch decreases.

The correct answer is "3. Both increase"

In fact, the frequency of a vibrating string is given by

where L is the length of hte string, T the tension and  the linear mass density. 
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.

This is what i found on google “kinetic energy. energy is transferred from one object to another when a reaction takes place. energy comes in many forms and can be transferred from one object to another as heat, light, or motion, to name a few. this energy would be in the form of motion, with the person lifting the blue ball to a higher level.” i hope this you
