The glare is the result of the specular reflection of the beam of light from an oncoming car. Normally a roadway would cause diffuse reflection due to its rough surface. But if the surface is wet, water can fill in the crevices and smooth out the surface.
Answer: 0.67 moles of
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 L at STP and contains avogadro's number of particles.
To calculate the moles, we use the equation:
According to stoichiometry:
3 moles of is produced by 2 moles of
Thus 1 mole of is produced by= of
Thus 0.67 moles of are required to produce 28.3 g of
Answer:
The wavelength of the radio wave is 3.003 m.
The energy of the radio wave is .
Explanation:
Frequency of the radio waves, ν = 99.9 MHz =
Wavelength and frequency are related to each other by realtion:
= Wavelength of the wave
c = speed of the light
ν = Frequency of the wave
The wavelength of the radio wave is 3.003 m.
The energy of the electromagnetic wave is given by Planck's equation:
h = Planck's constant =
The energy of the radio wave with 99.9 MHz frequency will be:
The energy of the radio wave is .
Explanation:
solve fsolve for x in terms of r.
rx + 24 = -9or x in tsolve for x in terms of r.
rx + 24 = -9erms of r.
solve for x in terms of r.
rx + 24 = -9
rx + 24 = -9
