Answer:
wavelength = 2m
Speed = 342m/s
Explanation:
The length of the pipe in terms of the wavelength is expressed as;
L = v/4 (For closed pipe)
v = 4L
Given
L = 50cm
L = 0.5m
Get the wavelength v;
v = 4(0.5)
v = 2.0m
Hence the wavelength is 2.0m
The speed of the sound in pipe is expressed as;
Fo = V/4L
Fo is the fundamental frequency
V is the speed of sound
L is the length of the pipe
171 = V/4(0.5)
V = 171 * 2
V = 342m/s
Hence the speed of the sound in pipe is 342m/s
Can anyone tell him how that is going
Answer:
Tension.
<em><u>tension</u></em> is the name of force that opposes or goes opposite of gravity
Hope this helps!
Compared to the charge on a proton, the amount of charge on an electron is same and has the opposite sign
To solve this problem it is necessary to apply the concepts related to Newton's second law, the definition of density and sum of forces in bodies.
From Newton's second law we understand that
Gravity at this case)
Where,
m = mass
a= acceleration
Also we know that
Part A) The buoyant force acting on the balloon is given as
As mass is equal to the density and Volume and acceleration equal to Gravity constant
PART B) The forces acting on the balloon would be given by the upper thrust force given by the fluid and its weight, then
PART C) The additional mass that can the balloon support in equilibrium is given as
