Answer is c that is he particles move perpendicular to the direction of the wave.
Answer: Use the formula q = m·ΔHv in which q = heat energy, m = mass, and ΔHv = heat of vaporization.
Answer:
There are 6.87 x 1023 atoms in 1.14 mol SO3, or sulfur trioxide :
If a particle undergoes simple harmonic motion with an amplitude of 0.21 meters, this means that the maximum displacement of the particle from its resting position is 0.21. For one period, it traveled from its starting position which is twice the amplitude and then back to its original position which is another distance that is twice the amplitude as well. Therefore, the total distance it traveled is 2*amplitude + 2*amplitude = 2*0.21 + 2*0.21 = 0.42 + 0.42 = 0.84 meters.
In the modern model of the atoms over 99.9℅ of the atom is made up of empty space
