C. Repeat the experiment multiple times in front of witnesses. At the time, most people were inclined to believe what the Catholic Church brainwashed them to believe. Galileo and some of his contemporaries performed experiments and achieved results that were contrary to the teachings of the Church, but most people were hesitant to believe them, so they had to be conducted multiple times in front of eyewitnesses for them to be accepted.
The S phase is when a Cell's DNA is copied. This is otherwise known as mid-interphase.
hope this helps!!
Based on the epicenter and the time of the arrival of the first S-wave, the first P-wave will arrive at 1:22 pm.
From the information given, it was stated that the epicenter of an earthquake is located 6,500 kilometers away from a seismic station and that the first S-wave arrived at this seismic station at 1:30 p.m.
Therefore, it should be noted that the first P-wave will have arrived 8 minutes earlier. This will be:
= 1:30 pm - 8 minutes
= 1:22 pm.

The answer is it's and experiment
Answer:
b. 457 Hz
Explanation:
Things including sound move like waves in the air. The distance between the crest of those waves is known as the wavelength, denoted by lambda (λ).
The wavelength of a sound can be calculated using the formula: λ = c/f
Where; λ= wavelength
c = speed of sound
f = frequency of sound
According to the question;
Wavelength of sound (λ) = 0.750m
Speed of sound (c) =342.5m/s
To calculate frequency (f), we make f the subject of the formula in λ = c/f
We initially cross multipy to have; c = λf
Divide both sides by λ to have; f = c/λ
We then calculate by inputting our values into the formula: f = c/λ
f = 342.5/0.750
f= 456.66
Approximately, the value of the frequency of the sound is 457Hz.
