Answer:
f = 0.65 hz
Explanation:
Given that,
The distance between adjacent crests, wavelength = 2.4 m
6 crests are observed to move past a given point along the medium in 9.1 seconds.
We need to find the frequency of these waves.
We know that,
Frequency = no. of waves per second.
So, the frequency of these waves is equal to 0.65 Hz.
Answer:
3.00
Explanation:
Since assuming oxygen as molecule so there are 6 atoms hence 3 molecules of oxygen hence 3 moles
H=100
d=0.1
k=1000
so, the options become 25,250,250,250. hence answer is A
