Answer:
6.6 beats per second
Explanation:
For a closed-end pipe, the fundamental frequency is given by
where
v is the speed of sound
L is the length of the pipe
Here we have
v = 346 m/s
L = 59.9 cm = 0.599 m
So the fundamental frequency is
The frequency of the signal generator is
So the beat frequency is given by the absolute value of the difference between the two frequencies:
which means that 6.6 beats per second are heard.
Answer:
Coal, crude oil, and natural gas are all considered fossil fuels all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago.

Even though you have not provided answer choices, I believe the answer is whatever letter corresponds with the answer: "It is rubbed with another object, and electrons move onto the rod."
Hope I helped!~ Brainliest appreciated.
Answer:
Equivalent Resistance of Resistors in Parallel is
1/R = 1/r1 + 1/r2 .....
1/R = 1/7 + 1/7 + 1/7
R= 7/3
R=2.33ohms
