Answer:
The solubility of a gas in a liquid occurs faster if the liquid is cooled. Hence the correct answer is option B.
Explanation:
The solubility of a gas in a liquid occurs faster than a solid. Solid solute takes much time to be dissolved in a solvent. This is because of the bonding. The bond of the solid is is much stronger when compared to the gaseous state. This is one of the reasons of gaseous dissolving faster than solid.
A gaseous state is defined as a material whose atoms are not closely attached with one another and is free to move in any direction. And when we have to mix gas in a liquid in a faster rate the liquid temperature should be lowered.
Answer: 0.04metres
Explanation:
The wavelength of a wave is the distance covered by the wave after one complete cycle. It is measured in metres, and represented by the symbol λ
Recall that Velocity (V) = Frequency F x wavelength λ
V = F λ
Make λ the subject formula
λ = V / F
In this case Frequency = 0.4 kHz
Convert kilohertz to hertz by multiplying 0.4 by 1000 i.e (0.4 x 1000Hz) = 400Hz
Velocity of wave = 16 m/s
So, λ = V / F
λ = 16 m/s / 400Hz
λ = 0.04metres
Thus, the wavelength of a wave is 0.04metres
Answer:
<h2>
merocrine, sebaceous, and apocrine</h2>
Explanation:
Merocrine: merocrine sweat glands are widely distributed across the body surface,
Sebaceous glands are located where hair follicles have existed,
apocrine sweat glands are found only in a few areas like axilla. Apocrine -are restricted to specific areas like the axilla, nipple of the breast, pubic region and around the anus area etc.
In scientific inquiry, observations can be made in many ways. This includes by using the senses, or performing an experiment.
Answer:
To back away
Explanation:
To back away because magnets are different and is they are put the wrong the way it moves back
