The modulated function is A(y) = 5y and the modulating function is ω = -2.
The superposition of the two given wave functions is given by:
ψ(y, t) = ψ1(y, t) + ψ2(y, t)
= (5y cos 7t) +(- 5y cos 9t)
The wave packet generated by the superposition of the two wave functions is given by:
ψ(y, t) = A(y)cosωt
= 5y(cos7t - cos9t)
Where A(y) = 5y is the modulated function and ω = (7 - 9) = -2 is the modulating function.
The wave packet is as shown:Wave packet plot

earth carries a net charge of about -5.0× 105 c . how many more electrons are there than protons on earth?
The net charge of the Earth is [tex]-5.0 x 10^5[/tex] coulombs, which means that the Earth has a net negative charge. This net negative charge is due to the presence of more electrons than protons on the Earth.
A coulomb is the unit of electric charge and is used to measure the amount of electric charge in an object. The charge of an electron is [tex]-1.6 x 10^-19[/tex]coulombs, and the charge of a proton is[tex]+1.6 x 10^-19[/tex]coulombs. These charges are equal in magnitude but opposite in sign, meaning that the charge of an electron is the exact opposite of the charge of a proton.
Since the Earth has a net negative charge, this means that there are more electrons than protons on the Earth. To calculate the exact number of extra electrons, we would need to know the magnitudes of the individual charges of electrons and protons. However, as a rough estimate, we can assume that the charges of electrons and protons are equal in magnitude and opposite in sign, so the number of extra electrons would be approximately equal to the net charge of Earth divided by the charge of a single electron.
Therefore, the estimated number of extra electrons is:
[tex](-5.0 x 10^5) / (-1.6 x 10^-19) = 3.125 x 10^24[/tex]
So, there are approximately [tex]3.125 x 10^24[/tex] more electrons than protons on Earth.

a sine wave has a frequency of 50 khz. how many cycles does it complete in 10ms
The sine wave completes 500 cycles in 10 ms.
To calculate the number of cycles completed by a sine wave, we need to know its frequency and the time interval.
Given:
Frequency = 50 kHz
Time interval = 10 ms
First, we need to convert the frequency to cycles per second (Hz) since the time interval is given in seconds. We know that 1 kHz = 1000 Hz.
Frequency = 50 kHz
Frequency = 50,000 Hz
Next, we can calculate the number of cycles using the formula:
Number of cycles = Frequency x Time interval
Number of cycles = 50,000 Hz x 10 ms
Number of cycles = 500 cycles
Therefore, the sine wave completes 500 cycles in 10 ms.
