Answer:
f = 5.65 Hz
Explanation:
The fundamental frequency of a string is given by following formula:
f = v/2L
where,
f = fundamental frequency
v = speed of wave = √(TL/m)
L = Length of String
m = Mass of String
T = Tension in String
Therefore,
f = √(TL/m)/2L
2f = √(T/Lm)
For initial condition:
T₁ = 600 N
f₁ = 110 Hz
2(110 Hz) = √(600 N/Lm)
√(600 N)/220 Hz = √Lm
Lm = 0.01239 N/s²
Now, for changed tension:
2f₂ = √(540 N/0.01239 N/s²)
f₂ = 208.7 Hz/2
f₂ = 104.35 Hz
So, the beat frequency will be:
f = f₁ - f₂
f = 110 Hz - 104.35 Hz
<u>f = 5.65 Hz</u>
You can find the volume of an irregular shaped object by immersing it in water in a beaker or other container with volume markings, and by seeing how much the level goes up.
Hi there!
I. They are the same.
Due to the Conservation of Momentum, an explosion as such means that the TOTAL momentum of the system (all of the pieces) is conserved.
Answer:
0.1 A
Explanation:
From the question,
V = IR............ Equation 1
Where V = Voltage, I = current, R = Resistance.
Given: I = 0.2 A, R = 10 ohms.
Substitute into equation 1
V = 0.2(10)
V = 2 volt,
If the resistor is replaced with a 20 resistor, The nwe current is
I = V/R................ Equation 2
I = 2/20
I = 0.1 A
