Answer:
23. Option B. Hertz
29. Refraction.
Explanation:
23. Determination of the unit of measurement of frequency.
Frequency is simply defined as the number of oscillation made in one second. Mathematically, frequency can be represented as:
Frequency = 1/period
f = 1/T
Period is measured in seconds.
Thus, the unit of frequency becomes
f = 1/T
f = 1/s = s¯¹ (Hertz)
Therefore, the unit of frequency is Hertz.
29. When a wave enters a new medium, the speed of the wave is uttered. This leads to the bending of the wave. When this occurs, we can say refraction has taken place.
Answer:
Using the kinetic theory, explain the rise of water in a glass capillary tube. ... Glass and water are composed of different molecules. The force of attraction between the glass molecules and the water molecules is stronger than that among water molecules hence the rise of water in the tube.

Answer:
The simple harmonic wave function is
Explanation:
Generally a sine wave is mathematically represented as
Here A is the amplitude which is mathematically represented as
substituting 0.25 m for Z we have that
k is the wave number which is mathematically represented as
substituting 1.1 m for (wavelength ) we have
=>
w is the angular frequency which is mathematically represented as
Here T is the period which is mathematically represented as
substituting 13 wave pass for n and for t
So
So
