:-
If a solid mass of a known volume is submerged in a container of a fluid, the volume of the fluid displaced is equal to the volume of the solid mass.
Hence volume of mercury displaced is
Answer:
f(3) = 362.32 Hz
Explanation:
the formula of frequency of open pipe is
f(n) = (n+1)v/2L
n = 0,1,2,3,... (the order)
0 for the first
1 for the second
v = speed of sound
L = the lenght of pipe
f(3) = (2+1) * 343 / 2 * 1,42
f(3) = 3 * 343 / 2.84
f(3) = 362.324 Hz (or you can write 362.32 Hz
Answer:
There are several reasons why SI is preferred to the old English system of measurement: ... SI uses base 10, just like our number system, so it is much easier to learn, remember and convert between units. The prefixes used in SI are from Latin and Greek, and they refer to the numbers that the terms represent.

Answer:
Explanation:
Use mathematical representations to describe a simple model for waves that includes how the amplitude of a wave is related to the energy in a wave. Patterns can be used to identify cause and effect relationships.
