The speed of sound in a medium is given by:
where
Ks is the bulk modulus
is the medium density
In our problem,
and
, so if we re-arrange the previous equation we can find the bulk modulus of sea water:
Answer:
Period of oscillation, T = 2 sec
Explanation:
It is given that,
Mass of the object, m = 5 kg
Spring constant of the spring, k = 50 N/m
This object is hanging from a coiled spring. We need to find the period of oscillation of the spring. The time period of oscillation of the spring is given by :
T = 1.98 sec
or
T = 2 sec
So, the period of oscillation is about 2 seconds. Hence, this is the required solution.
Answer:
I'm thinkin' it's D. I can't really provide an explanation though, sorry but I have a strong feeling that it is D.
Explanation:
Answer:
