Out of the choices given, the best choice to explain the direction of the moving force of air is from area o high pressure to areas of low pressure. The correct answer is B.
Answer:
When an electron is hit by a photon of light, it absorbs the quanta of energy the photon was carrying and moves to a higher energy state. One way of thinking about this higher energy state is to imagine that the electron is now moving faster, (it has just been "hit" by a rapidly moving photon)
A photon is a quantum of EM radiation. Its energy is given by E = hf and is related to the frequency f and wavelength λ of the radiation by. E=hf=hcλ(energy of a photon) E = h f = h c λ (energy of a photon) , where E is the energy of a single photon and c is the speed of light.
Answer:
n1 sin θ1 = n2 sin θ2 Snell's Law (θ1 is the angle of incidence)
sin θ2 = n1 / n2 * sin θ1
sin θ2 = 2.4 / 1.33 * sin θ1
sin θ2 = 1.80 * .407 = .734
θ2 = 47.2 deg

</span>Question : What part of the plant that transport
water from its root to its leaves.
The answer is the stem. The stem connects the plant’s root and leaves, it is
responsible for transporting water that is absorbed by the root going to the
leaves, it is also responsible for transporting nutrients absorbed with the
leaves coming from the sun or any nutrients going to the roots to make is grow
faster and healthy. Stem is the one that connects leaves and root and the one
the does the transporting job.</span>
