Explanation :

The amplitude of the wave illustrates the energy of the wave. The energy of the depends on the amplitude and the frequency of the wave.

The maximum distance covered by the wave is called its amplitude. The topmost point on the wave is called its crest and the down most point is called its trough (as shown in the attached figure).

From the given data, the wave having the amplitude of 3 cm has the least energy while the wave having an amplitude of 12 cm have maximum energy.

So, the correct order of the wave from the lowest energy to the highest energy is :

1 < 4 < 2 < 3

Hence, this is the required solution.

A charged particle A exerts a force of 2.45 μN to the right on charged particle B when the particles are 12.2 mm apart. Particle

Brilliant_brown [7]

Answer:

$F_2 = 1.10 \mu N$

Explanation:

As we know that the electrostatic force is a based upon inverse square law

so we have

$F = \frac{kq_1q_2}{r^2}$

now since it depends inverse on the square of the distance so we can say

$\frac{F_1}{F_2} = \frac{r_2^2}{r_1^2}$

now we know that

$r_2 = 18.2 mm$

$r_1 = 12.2 mm$

also we know that

$F_1 = 2.45 \mu N$

now from above equation we have

$F_2 = \frac{r_1^2}{r_2^2} F_1$

$F_2 = \frac{12.2^2}{18.2^2}(2.45\mu N)$

$F_2 = 1.10 \mu N$

A measure of the average kinetic energy of the individual particles in an object is called

svlad2 [7]

<h2>Answer: Temperature </h2>

Temperature is a physical quantity that reflects the amount of heat in a body or medium. This amount of heat is related to the internal energy of a system (thermodynamically speaking), <u>according to the movement (speed) of each of the particles that compose it</u>, this means that it is related to its kinetic energy.

Therefore, the higher the kinetic energy, the higher the thermal energy in the system and the higher the temperature.
