Answer:
Sound energy is the form of energy generated when an object vibrates. Once produced through vibrations, sound energy is transferred in waves through mediums such as air and water before it reaches your ears.
Answer:
The sample of lead has a volume of 11.1 cm³
Explanation:
<u>Step 1:</u> Data given
x cm³ lead has a density of 11.3 g/cm³
it has the same mass as 330cm³ of a piece of redwood with density 0.38g/cm³
<u>Step 2</u>: Calculate mass of the piece of redwood
Density = mass/volume
mass = density * volume
Mass of the piece of redwood = 0.38 g/cm³ * 330cm³ = 125.4 grams
Since the sample of lead has the same mass, it also has a mass of 125.4 grams
<u>Step 3</u>: Calculate volume of the lead
Density = mass/ volume
Volume = mass/ density
Volume of lead = 125.4g / 11.3g/cm³ = 11.097 cm³≈11.1 cm³
The sample of lead has a volume of 11.1 cm³

<h2>Hey rose why you deleted my comments</h2>
Answer:
Molecules in the gas move faster due to the fact they have more energy
Explanation:
If you put more heat the higher the volume will be. Less heat means less volume.
(have a great day!)
