Answer:
To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x,t)=Asin(kx−ωt+ϕ).
The amplitude can be read straight from the equation and is equal to A.
The period of the wave can be derived from the angular frequency (T=2πω).
The length of the shortest pipe which is l2 will be 0.018m
<h3>
What is Length?</h3>
This is defined as the measurement or extent of a substance from end to end. The formula is shown below:
L = v/f where v is speed , f is frequency
f1 = 25hz , f2 = 19khz
The length for both sides is seen below:
l1 = 343/25 = 13.72m
l2 = 343/19000 = 0.018m.
The length of the shortest pipe is therefore 0.018m.

Answer:
- 0.5 m/s²
Explanation:
m = mass of the clarinet case = 3.230 kg
W = weight of the clarinet case in downward direction
a = vertical acceleration of the case
Weight of the clarinet case is given as
W = mg
W = 3.230 x 9.8
W = 31.654 N
F = Upward force applied = 30.10 N
Force equation for the motion of the case is given as
F - W = ma
30.10 - 31.654 = 3.230 a
a = - 0.5 m/s²
Answer:
The magnetic field is 1.23 T in upward.
Explanation:
Given that,
Mass = 0.2
Length = 0.8 m
Current = 2 A
We need to calculate the magnetic field
If the net force on the rod is zero so the magnetic field is equal to the weight.
Using formula of magnetic force
Put the value into the formula
For direction, using right hand rule
In right hand rule, Thumb represents the force, forefinger represents the magnetic field and the middle finger represents the current.
So,
The direction of the magnetic field is upward.
Hence, The magnetic field is 1.23 T in upward.
Actually it all comes about when we fail to complete certain doses of medication prescribed by doctors, for example, I have typhoid and I am given medication to help kill that bacteria I take half a dose and decide that I'm okay and the other half I discard it what happens is that the ”partially” killed bacteria now recognizes the drug I am using and adapts itself and its offspring to be resistant to that drug
Hence it is actually because of uncompleted medication
