c. energy
d. electronics
Answer:
food
Explanation:
Answer:
The juice contains sugars, plant pigments, and other chemicals dissolved in water. This is a solution. The pieces of orange pulp will rise to the top or settle to the bottom of the juice if it is allowed to sit. The pieces of pulp mixed with the juice form a suspension.
Explanation:
In chemistry, a suspension is a heterogeneous mixture containingsolid particles that are sufficiently large for sedimentation. Usually they must be larger than one micrometer. A Suspension is a heterogeneous mixture in which the soluteparticles do not dissolve but get suspended throughout the bulk of the medium.a solution is a homogeneous mixture composed of two or moresubstances. In such a mixture, a solute is a substance dissolved in another substance, known asa solvent.. it is considered a solution andsuspension because the orange juice mix with water while the pulp did not andretained as solid
Before solving this question first we have to understand longitudinal wave and transverse wave.
A longitudinal wave is a wave in which the particles of the medium vibrate parallel to the direction of propagation of wave. In this type of wave one will notice compressions and rarefactions. Compressions are high pressure zones where the particles of the medium are close to each other . The rarefactions are low pressure zones where there will be large separation between particles.
A longitudinal wave is a repeated motion of compressions and rarefactions. The particle of the medium show a little displacement along the direction of wave.
A transverse wave is a wave in which the particle vibration is perpendicular to the direction of propagation of wave .In this type of wave one will notice crests and troughs.It is a repeated motion of crests and troughs.
Sound wave is a longitudinal wave. When it passes through air it forms rarefactions and compressions.
Hence from the above we get that out of the four options given in the question only option B is right which depicts that the air particles move parallel to the sound waves.
If you are bombarded with 1.00 mol of photons with a wavelength of 370 nm, you are being subjected to 322 kJ/mol of energy.
The energy of a photon is given by the equation:
E = hc/λ
where:
h = Planck's constant = 6.626 x J s
c = speed of light = 2.998 x m/s
λ = wavelength of the radiation
To find the energy of a mole of photons, we need to multiply the energy of a single photon by Avogadro's number (6.022 x ).
First, we need to convert the wavelength of the radiation from nanometers to meters:
370 nm = 370 x m
Now, we can use the equation to calculate the energy of a single photon:
E = hc/λ
E = (6.626 x J s) x (2.998 x m/s) / (370 x m)
E = 5.35 x J
Next, we can calculate the energy of a mole of photons:
(5.35 x J/photon) x (6.022 x photons/mol) = 3.22 x J/mol
Finally, we can convert the energy to kilojoules per mole of photons:
3.22 x J/mol = 322 kJ/mol
