In order to answer this question we might first want to think about what is electromagnetic radiation. In essence it’s light, just some of the wavelengths are too long or too short for us to see.
We can think about it as two oscillating sinusoidal (goes up and down) waves, one is electric, the other is magnetic.
Because we’re dealing in waves, that means we can calculate their frequency, wavelength, amplitude (brightness) and period.
To calculate it we can use E=hc/lambda
Where E = jewels of energy
h = Planck’s constant
c = speed of light
Lambda = wavelength
It doesn’t really matter for this question what those things mean, just note that it takes more energy to have a shorter wavelength, or less energy to have a longer wavelength.
So now we can answer the question. Light of a longer wavelength has less energy than that of a shorter wavelength. So, when long wavelengths are absorbed by matter (atoms) they will give those atoms less energy. So, either it will pass through the object entirely or it will make the atoms vibrate a little bit more than they already are and we call that thermal energy, or heat.
If high energy wavelengths are passing through matter then they will be giving those atoms a lot of energy, sometimes even ionizing the atoms.
Which, if you’re a living thing can be very bad for your cells.
I hope that helps.
Answer:
The velocity of flow in 10in pipe is 4.16 ft/s.
Explanation:
Given that
Specific gravity = 0.8
Viscosity =0.00042
For pipe 1
For pipe 1
If we assume that flow in the both pipe is laminar
For laminar flow through circular pipe
So same pressure drop we can say that
So the velocity of flow in 10in pipe is 4.16 ft/s.
Answer:
Boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
Explanation:
From the conformations, the boat conformation cis 1,4-dimethyl cyclohexane is least stable due to the fact that two methyl groups are located in opposite direction to each other, this leads to the production of a higher strain. Similarly, Chair conformations appear more stable than boat conformation. Hence, energy is inversely proportional to stability. As a result of the aforementioned, boat conformation cis 1,4-dimethyl cyclohexane has the highest energy.
Answer:
bromine,mercury ,caesium,gallium,rubidium and francium
Explanation:
Based on Hess's Law:
<span>2 N2(g) + 6 O2(g) + 2 H2(g) −→ 4 HNO3(l) ∆Hf = (−171.9 kJ/mol)(4 mol) </span>
<span>2 H2O(l) −→ 2 H2(g) + O2(g) ∆Hf = (-283.8 kJ/mol)(2 mol)(-1) →times -1, rxn is reversed </span>
<span>4 HNO3(l)−→ 2 N2O5(g) + 2 H2O(l) ∆Hf = (-76.4 kJ/mol)(2 mol)(-1) →times -1, rxn is reversed </span>
<span>2 N2(g) + 5 O2(g) −→ 2 N2O5(g) ∆H0 = 32.8 kJ</span>
