They only conduct when they are in solution form, because then their ions become mobile, and the ions conduct electricity.
Hope this helps!
Answer:
They interact in a lot of ways, prey, predator, etc.
Answer:
The intensity of sound at a rock concert is louder than that of a whisper by a factor of 1 x 10¹⁰
Explanation:
Given;
rock concert sound intensity level, β₁ = 120 dB
whisper sound intensity level, β₂ = 20 dB
The sound intensity level is given as;
where;
I₀ is the threshold sound intensity of hearing = 10⁻¹² W/m²
I is the sound intensity
Intensity of sound at rock concert ;
The intensity of sound of a whisper;
Determine the factor by which the intensity of sound at a rock concert louder than that of a whisper
Therefore, the intensity of sound at a rock concert is louder than that of a whisper by a factor of 1 x 10¹⁰
Answer: the air above a wildfire
Explanation:
First part of question is: The diagram shows currents that form as water is heated.
When water is being heated from below, convection currents are used. This happens when the molecules at the bottom are heated thus giving them energy and enabling them rise to the surface. The colder water at the surface will therefore sink to the bottom where is is heated making it rise as well and the process is repeated.
When a wildfire is ignited, the concept is the same. The air above the wildfire is the water in this scenario. It is heated at the bottom and rises thereby forcing the air above to come down and be heated as well. Both situations uses convectional currents.
Answer:
we can conclude that mass of air that has entered the tank is 7.80 kg.
Explanation:
given data
volume = 1.85 m³
density 1 = 1.18 kg/m³
density 2 = 5.30 kg/m³
solution
we know that density is the mass present in per unit volume so that is
mass = density × volume ........................1
here density is change so put here value in equation 1 we get
mass = ( 5.30 - 1.18 ) kg/m³ × 1.85 m³
solve it we get
mass = 7.807 kg
so we can conclude that mass of air that has entered the tank is 7.80 kg.
