In a longitudinal wave, the particles of matter in the medium vibrate by pushing together and moving apart. In a transverse wave

Lilit [14]

Answer:

C. The particles in longitudinal waves travel parallel to the direction of the wave, whereas the particles in transverse waves travel perpendicular to the direction of the wave.

Explanation:

Longitudinal waves are waves that propagates energy from their source by movement of particles in a direction parallel to the wave motion.

Transverse waves produce oscillations that are perpendicular to the direction of propagation.

Examples of longitudinal waves are sound waves, seismic p-waves
Examples of transverse waves are electromagnetic waves

A wave is a disturbance that transmits energy from one point to another.

When an object such as a plastic comb is charged by rubbing it with a cloth, the net charge is typically a few microcoulombs. If

The concept required to solve this problem is quantization of charge.

First the number of electrons will be calculated and then the total mass of the charge.

With these data it will be possible to calculate the percentage of load in the mass.

$Q= ne$

Here Q is the charge, n is the number of electrons and e is the charge on the electron

$n = \frac{Q}{e}$

Replacing,

$n = \frac{4*10^{-6}C}{1.6*10^{-19}}$

$n = 2.5 * 10^{13}77$

According to the quantization of charge the charge is defined as product of the number of electron and the charge on the electron

The total mass of the charge is

$m= nm_e$

Here,

m = Mass of the charge

n = Number of electrons

$m_e$ = Mass of the electron

$\text{Percentage change} = \frac{nm_e}{M}*100$

Replacing we have

$\text{Percentage change} = \frac{(2.5*10^13)(9.1*10^{-28})}{33}*100$

$\text{Percentage change} = 6.9*10^{-14} \%$
