Two factors affect the speed of a sound wave as it travels through a medium

Answers

Answer: The density and the temperature

Explanation:

Sound needs a medium to travel. The medium particles vibrate and transfer energy. Sound travels by compression and rarefaction of the medium particles. Thus, the speed of the sound varies with the density of the medium. If the medium is denser, the particles would be closer and energy would transmitted faster because there would be more rapid collisions which means that speed of the sound will be greater in a denser medium.Thus, speed of sound is fastest in solids than in liquids and is least in gases.

Speed of sound also depends on temperature. Greater the temperature, the particles would vibrate faster which would lead to again more inter particle collisions. Thus, the speed of sound would increase with increase in temperature.

The density of the medium and temperature affect the speed of sound waves.

The direction of motion for a series of wave fronts is represented with a(n) _____.wavelength

The direction of motion for a series of wave fronts is represented with a(n) ray

suppose that i suspect that running my ceiling fan stirs up dust and causes my table to become dusty. how could i use the method of concomitant variations to confirm this?

Answers

The use the method of concomitant variations we need to identify the variables, establish a baseline, introduce variation and compare results.

To use the method of concomitant variations to confirm whether running your ceiling fan stirs up dust and causes your table to become dusty, follow these steps:

1. Identify the variables: In this case, the independent variable is the operation of the ceiling fan (on or off), and the dependent variable is the dust accumulation on your table.

2. Establish a baseline: Observe the dust accumulation on your table when the ceiling fan is off for a specific period, let's say 24 hours. Document the amount of dust on the table.

3. Introduce variation: Turn on the ceiling fan and observe the dust accumulation on your table for the same period (24 hours). Document the amount of dust on the table.

4. Compare results: Compare the dust levels on your table when the ceiling fan was off versus when it was on. If there is a concomitant (simultaneous) increase in dust accumulation when the fan is on, this suggests a relationship between the operation of the ceiling fan and the dust on your table.

5. Repeat the process: To strengthen your evidence, perform the same experiment multiple times, alternating between turning the fan on and off. If the pattern of increased dust accumulation consistently occurs when the fan is on, this further supports the hypothesis that the ceiling fan stirs up dust and causes your table to become dusty.

The electron configuration of nitrogen (N) is

Answers

Answer: $1s^22s^22p^3$

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration for nitrogen with atomic number of 7 which also contains 7 electrons is:

$N:7:1s^22s^22p^3$

The electron configuration of (N) is 1s²2s²2p³
