In the space below, write one sentence describing how particles move in a longitudinal wave. Then, write two more sentences describing how wavelength and amplitude are measured.

First statement: The particles which are displaced is parallel to the direction of energy transport or to the direction the wave travels.

Second statement: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position.

Third statement: wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.

Explanation:

Wave can be defined as a displacement that occurs in a medium, from one point to another. There are two different kinds of waves in physics which includes:

- Longitudinal wave and

- Transverse wave.

In a longitudinal wave, particles are displaced parallel to the direction of energy transport or to the direction the wave travels. There are also different properties which can be used to describe a longitudinal wave and they includes:

- amplitude: amplitude is measured by determining how far the molecules of the medium have been displaced from their normal rest position in a longitudinal wave.

- wavelength is measured through determining the distance between one point on the wave and the corresponding point on the next one.

would be false hope this out

answer: at 24 february, 2014 the population gets twice of its initial population.

explanation:

since we have given that

the population for alpha city, t years after january 1, 2004 is given as

first we find out the initial population, i.e. t=0,

so, our quadratic equation becomes,

according to question, we have said that if the population has twice its initial population, then it becomes

so, time taken to reach this above mentioned population is given by

now, we know that time can't be negative so, we take t=9.149 years.

hence, at 24 february, 2014 the population gets twice of its initial population.
