Answer:

Sound travels through vibration

Explanation:

As you can feel when you talk your vocal cords vibrate. This vibration creates sound. It vibrates other particles and eventually vibrates your eardrum. If you have another question sound travels through spheres through the air.

It transfers energy through the source of the sound. Your ear detects sound waves when vibrating air particles cause your ear drum to vibrate

Which of the following lists the typical steps of the scientific method in the
irinina [24]

B. Ask a question - Hypothesize - Experiment - Analyze - Draw  a conclusion

Explanation:

The scientific method is a systematic approach in which investigations are conducted in science.

It follows systematic manner;

  • An observation in nature is made using the senses.
  • Questions are then asked about such observations. This is the inquiry phase.
  • A hypothesis is then formula to predict what might cause the observation.
  • Experiments are then conducted
  • The results are analyzed and a conclusion is drawn

A car slows down from 27.7 m/s <br> to 10.9 m/s in 2.37 s. <br> What is its acceleration?
Sunny_sXe [5.5K]

Answer:

- 7.088 m/s²

Explanation:

As we know that,

★ Acceleration = Change in velocity/Time

→ a = (v - u)/t

Here,

  • Initial velocity (u) = 27.7 m/s
  • Final velocity (v) = 10.9 m/s

→ a = (10.9 m/s - 27.7 m/s)/2.37 s

→ a = -16.8/2.37 m/s²

→ <u>a</u><u> </u><u>=</u><u> </u><u>-</u><u>7</u><u>.</u><u>0</u><u>8</u><u>8</u><u> </u><u>m/s²</u> [Answer]

Negative sign denotes that the velocity is decreasing.

A student measures the volume of a gas sample at several different temperatures. The results are tabulated as follows:Temperatur
lapo4ka [179]

Answer:

Check the first and the third choices:

<u><em /></u>

  • <u><em>a. The temperature of a gas is directly proportional to its volume</em></u>
  • <u><em>b. The temperature-to-volume ratio of a gas is constant.</em></u>

Explanation:

Rewrite the table for better understanding:

Temperature of gas (K)     Volume of gas (L)

     298                                     4.55

     315                                      4.81

     325                                     4.96

     335                                        ?

Calculate the ratios temperature to volume with 3 significant figures:

  • 298 / 4.55 = 65.5
  • 315 / 4.81 = 65.5
  • 325 / 4.96 = 65.5

Then, those numbers show a <u><em>constant temperature-to-volume ratio</em></u>, which may be expressed in a formula as:

  • Temperature / Volume = constant, which is a directly proportional variation (the volume increases in a constant proportion to the increase of the temperature).

Hence, the correct choices are:

  • The temperature of a gas is directly proportional to its volume (first statement), and
  • The emperature-to-volume ratio of a gas is constant (third statement).
