A longitudinal wave has a compression to compression distance of 10 m it takes the wave of 5s to pass a point what is the wavelength of the longitudinal wave

The work that must be done on charges brought from infinity to a spherical shell of radius R = 0.100 m and total charge Q = 125 mc is 602J. Hence, option B is the correct answer to this question.

To calculate the work that must be done on charges brought from infinity to a spherical shell of radius R, we can use the formula for the electric potential energy, which is given by U = kq1q2/r

Where k is the Coulomb constant, q1 and q2 are the charges, and r is the distance between the charges.

In this case, the work done on a single charge of q = Q/n, where Q is the total charge on the shell and n is the number of charges, brought from infinity to a distance of r = R from the center of the spherical shell is given by:

W = qU = q(kq/R) = kq^2/R

Since the total charge on the spherical shell is Q = 125 mc and the radius of the shell is R = 0.100 m, the work done on each charge is:

W = kq^2/R = (8.99x10^9 N.m^2/C^2)(125x10^-6 C)^2/(0.100 m) = 602 J

Therefore, the work that must be done on charges brought from infinity to a spherical shell of radius R = 0.100 m and total charge Q = 125 mc is 602 J.

The common velocity of clay 1 and clay 2 is 15 m/s. Option C

We know that a collision can be said to be inelastic when the momentum and the kinetic energy are not conserved. This implies that rather than having the objects move out in different directions, the objects would rather stick together and just move in the same direction.

In this case we would also need the law of the conservation of linear momentum. Recall that according to this law, the momentum before collision  would just be the same as the momentum after Collison.

Thus;

Momentum before collision = momentum after Collison

(2100 * 20) + (2500 * 0) = (2100 + 2500)v

Where v is the common velocity

v = 42000/4600

v =  15 m/s

This describes the concept of self-extension. When individuals are able to exercise power and control over objects and possessions, they may begin to view these things as extensions of themselves.

We may understand and express our self-identity through our possessions. When opportunities for receiving external validation of self are scarce, as can be the case as a result of institutionalization, for the elderly, things serve as crucial archives of memories of one's self-identity in the past.

William James claimed that the things, places, or even persons that carry the label "my" are what make up the material self. These things are seen as extensions of people's identities. For instance, your clothing, which you refer to as "my wardrobe," expresses certain facets of your personality.

(a) To find the distance between two points that differ in phase by π/3 radians, we can use the wavelength of the wave, which is given by the speed of the wave divided by the frequency:

Wavelength = Speed of wave / Frequency

Given that the frequency is 500 Hz, the wavelength is:

Wavelength = 350 m/s / 500 Hz = 0.7 m

The phase difference between the two points is equal to the difference in the phase of the wave at these points. The phase difference in radians is given by the product of the wave number and the distance between the points.

The wave number is equal to 2pi/wavelength, so:

k = 2π / wavelength = 2*π / 0.7 m = 8.6 rad/m

The distance between the two points that differ in phase by pi/3 rad is given by:

Distance = π/3 / k = π/3 / 8.6 rad/m = 0.035 m

(b) To find the phase difference between two displacements at a certain point at times 1.00 ms apart, we can use the angular frequency of the wave, which is given by the product of 2π and the frequency:

ω = 2π * frequency = 2π * 500 Hz = 3141.59 rad/s

The phase difference between two displacements at a certain point at times 1.00 ms apart is given by the product of the angular frequency and the time interval.

Given that the time interval is 1.00 ms = 0.001 s, the phase difference is:

Δφ = ω * time interval = 3141.59 rad/s * 0.001 s = 3.14 rad

Therefore, the phase difference between two displacements at a certain point at times 1.00 ms apart is 3.14 rad.

These gases are colorless, odorless, and tasteless. They are generally unreactive and do not form compounds with other elements. This is because their outermost electron shells are filled and therefore they do not gain or lose electrons easily.

At -6cm from small charge on the x-axis is the electric potential zero.

Electric potential is the effort required to move a unit charge from one point to another while battling an electric field. Though any location outside the range of the electric field charge can be used, Earth is typically used as the reference point.

The diagram depicts the forces acting on a positive charge (q) that is situated between two plates (A and B) of an electric field (E). To move the charge from plate A to plate B, an equal and opposite force (F′ = qE) must be applied because the electric force F exerted by the field on the positive charge is F = qE. The work W required to move the positive charge over a distance d is W = F′d = qEd.

Two unlike charges are separated by a distance d two zero potentials points are obtained one between the charges(x)

The change in decibels ( Δβ2, Δβ4, and Δβ8) corresponding to m=2, m=4, and m=8 is 3.0103 dB, 6.0206 dB, 9.03 dB respectively.

A change in decibels (dB) is a measure of the relative change in sound or electrical power level. A change of 3 dB is considered a small change in level, while a change of 10 dB is considered a significant change. It is important to note that dB is a logarithmic unit, meaning that a change of 10 dB represents a ten-fold increase or decrease in power level. For example, an increase of 10 dB in sound level is equivalent to a ten-fold increase in the sound's power, while a decrease of 10 dB represents a ten-fold decrease in the sound's power.

To calculate the change in decibels (Δβ) corresponding to a change in the magnitude of the sound (m), we use the formula:

Δβ = 10 * log10(m)

where m is the ratio of the new sound pressure level to the original sound pressure level.

For m = 2:

Δβ2 = 10 * log10(2) = 3.0103 dB

For m = 4:

Δβ4 = 10 * log10(4) = 6.0206 dB

For m = 8:

Δβ8 = 10 * log10(8) = 9.03 dB

A) runner a's distance will be 115.2 m, and runner b's distance will be 120.7 m.

Distance is a numerical measurement of how far apart two objects or points are from one another. Distance can be measured in a variety of ways including miles, kilometers, feet, and meters.

To solve this problem, we need to use the equation d = rt, where d is the distance, r is the rate, and t is the time. Since both runners are running at a constant speed, we can assume the rate (r) is the same for both.
We can calculate the rate by using the information that both runners were 64 m away from the starting point after 25 s. We can plug this information into the equation to get:
64 m = r * 25 s
Solving for r, we get:
r = 2.56 m/s
Now that we have the rate, we can plug it into the equation to calculate the distances for both runners at time t = 45 s.
For runner a (who started at t = 0s), the distance will be:
d = 2.56 m/s * 45 s
d = 115.2 m
For runner b (who started at t = 2.5 s), the distance will be:

The net force on the dog is given by:

fnet = fgravity + felevator

As the elevator is accelerating downward, the net force is equal to the gravitational force minus the force by the elevator. So:

felevator = m x a

where m is the mass of the dog (5.0 kg) and a is the acceleration of the elevator (1.20 m/s^2).

So, fnet = m x g - m x a

fnet = |m x g - m x a| = |5.0 kg * 9.8 m/s^2 - 5.0 kg * 1.20 m/s^2| = 49 N

So the magnitude of the normal force by the elevator on the dog is 49 N.

When the elevator accelerates downward the apparent weight of the man becomes zero. This is because of the reason that both the man and the lift are moving downwards with the same acceleration 'g' and so there is no force of action and reaction between them.
