Why will liquids evaporate even at room temperature?
mr Goodwill [35]
<h2>It can happen when liquids are cold or when they are warm. ... It turns out that all liquids can evaporate at room temperature and normal air pressure. Evaporation happens when atoms or molecules escape from the liquid and turn into a vapor. Not all of the molecules in a liquid have the same energy.</h2>

If a wave has a wavelength of 13 meters and a period of 0.005, what's the velocity of the wave? A. 2,600 m/s B. 260 m/s C. 1,300
Rina8888 [55]

Answer:

V = 2600ms⁻¹

Explanation:

Given parameters:

Wavelength(λ) = 13meters

Period (T) = 0.005s

Period(T) is the time it takes for a full cycle of vibration to pass through. It's unit is in seconds (s)

The Velocity of waves is expressed as:

V = fλ

Where f = frequency(s⁻¹)

Frequency of a wave is the number of waves that passes through a point per unit time

f = 1/T

Where T is the period

We can therefore express Velocity of waves as a function of period

V = λ/T

Inputing the parameters, we have:

V = 13m / 0.005s

V = 2600ms⁻¹
