A long stairway with a metal handrail runs between the houses of Amelia and her friend Michelle. After getting their parents' pe

rmission, the two girls often play near the stairs. One day, Michelle stands at the top of the steps and taps the railing with a stone. Amelia stands at the bottom of the steps with her right ear pressed against the railing.
Amelia sees Michelle tap the railing, then she hears the sound with the ear that is pressed against the railing. Last, Amelia hears the sound with her other ear. Why did Amelia hear the sound with her right ear before her left ear?
A.
because light travels more quickly through air than sound does
B.
because the particles that carry sound energy travel more quickly through solids than through gases
C.
because the waves that carry sound energy travel more quickly through solids than through gases
D.
because her right ear was closer to Michelle, who was the source of the sound

Heating up an object can cause it to
MAXImum [283]

Answer:

We know that kinetic energy is one of the forms of internal energy, so the release of heat from an object causes a decrease in the average kinetic energy of its particles.

When an atom gains an electron to become an ion what happens to its size?
irina [24]
It stays roughly the same size. Electrons have a barely imperceptible mass so the overall mass of the atom is changed very little.

Which of the following leads to a higher rate of diffusion?
miv72 [106K]
<h3><u>Answer;</u></h3>

Higher velocity of particles

<h3><u>Explanation;</u></h3>

The diffusion rate is determined by a variety of factors which includes;

  • Temperature such that the higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly and the diffusion rate will be high.
  • Concentration gradient such that the greater the difference in concentration, the quicker the rate of diffusion.
  • Higher velocity of particles increases the diffusion rate as this means more kinetic energy by the particles and hence the particles will mix and move faster, thus higher diffusion rate.
