Question 1's answer is, if we change the length of the string allowed to vibrate, then the frequency (and pitch) of the string vibration will change. This is because the tension of the string determines the pitch.
Question 2's answer is 2. This can be solved by doing simple division. 30/15 = 2.
Question 3's answer is short bars. Each bar on a xylophone produces a different pitch; the shorter the bar, the higher the pitch.
Hope this helps.
The conversion factor needed to change from kilometers to meters is
D) 1000
Explanation:
The meter (m) is the SI units to measure distance.
The kilometer (km) is a sub-unit, where the prefix 'kilo' stands for , or 1000. This means that:
Therefore, if we have a length expressed in kilometers, we just need to multiply by 1000 to get the corresponding length in meters.
For instance, if we have a length of
L = 3.47 km
To convert in meters, we do:

The correct answer, is Option C, I hope this helps :)
Answer:
increases the voltage output
Explanation:
By Increasing the number of turns on the generator coil , the output volatge of a generator increases. However, there are various other methods availbble to increase the output voltage of a generator. Some of these can be
1. By increasing the rpm of generator coil.
2. By using stronger magnets
