Answer:
Beat frequency is determined by the number of beats per second one hears from the sound. It can also be determined by taking the difference in frequency of the two notes that interfere to produce the beat.
Explanation:
Beat frequency is determined by the number of beats per second one hears from the sound.
Assuming the sound pulses is coming from two tuning forks;
- Frequency of the first tuning fork (F₁) is known as 240Hz
- Frequency of the second tuning fork (F₂) is not known
- there are 8 beats in 2 seconds
Beat Frequency = number of beats/time
Beat Frequency = 8/2 = 4Hz
Beat Frequency = F₂ - F₁
±4 = F₂ - 240
4 = F₂ - 240
4+240 = F₂
244 = F₂
F₂ = 244 Hz
-4 = F₂ - 240
-4 + 240 = F₂
F₂ = 236 Hz
The percentage uncertainty in the beat frequency is
4 /240 = 0.0167 = 1.67%
To reduce the percentage uncertainty in the beat frequency
A tuning fork of almost the same frequency as the first tuning fork are used to produce sound pulses, let's say the frequency of the second tuning fork is 241 Hz.
The beat frequency = 241Hz -240Hz = I Hz
Then, the percentage uncertainty = 1/240 = 0.00416 =0.416%
Answer:
6 kg
Explanation:
F=ma
F is Force(newtons)
m is mass(kg)
a is acceleration(m/s^2)
Plug in the numbers
3000 = m(500)
divide both sides by 500 to cancel out the 500.
3000/500=6
6 = m
6kg is the mass
The correct answer is letter c. Enthalpy (H). Entrophy means the measure of the degree of disorder. Gibbs energy formulated by Josiah Willard Gibbs and it is the energy associated with a chemical reaction to do work.Fusion is the combining light nuclei into a heavier nucleus.
Acceleration represents the change in velocity.
The acceleration of the body is provided by the tension in the rope.
<h3>What is centripetal acceleration?</h3>
The centripetal acceleration is given by a = v^2/r. v = velocity of the body, r = radius
a = (8.40 m/s)^2/(8.50 m)
a = 8.3 m/s^2
The tension in the rope is the force that provides the centripetal force in the rope.
