The frequency of the wave is 4 Hz
Explanation:
The relationship between wave, frequency and speed of a wave is given by the equation:

where
v is the speed of the wave
f is the frequency
is the wavelength
For the wave in this problem, we have:
is the speed
is the wavelength
Solving the equation for f, we find its frequency:

The wavelength of the wave is 1.16m and the velocity is 23.64m/s.
To find the answer, we have to know more about the Transverse waves.

How to find different parameters of a wave?</h3>
- The displacement of the string as a function of position and time, y(x,t), when the wave traveling along a string lying along the x-axis is given as,

- Comparing this with the general form of wave equation, we get,

- We have to find the wavelength of the wave, for this, we have the expression as,

- We have to find the velocity of the wave,

Thus, we can conclude that, the wavelength of the wave is 1.16m and the velocity is 23.64m/s

Answer:
0.0192A
Explanation:
Since, the reading of the galvanometer is 0 A, the voltage across the resistance R will be:
Step 1
VR = V2
VR = 3.00v
Step 2
Calculating the current through the resistance R as below,
IR = V1 - V2 /R1
IR = 12 - 3 /468
IR =0.0192A
The answer is A.
Explanation:
We know that the average acceleration a for an interval of time Δt is expressed as:
a = Δv
Δt
where Δv is the change in velocity that occurs during Δt.
e formula for the instantaneous acceleration a is almost the same, except that we need to indicate that we're interested in knowing what the ratio of Δv to Δt approaches as Δt approaches zero.
We can indicate that by using the limit notation.
So, the formula for the instantaneous acceleration is:
a = lim Δv
Δt→0 Δt
We have that there is a formula connecting these three. V=I*R where V is voltage, I is the current and R is the resistance. Substituting, we get that V=210 Volta, which is the unit of measurement for voltage. You can think of the relationship in the following way : The energy of the field is equal to the flow of the field times the resistance that it meets.
