Option C. increasing the thickness of the string used.

Because thick strings vibrate slower and with lower frequencies than thin strings.

The correct option is C.

The pitch of a string refers to the quality of sound that is produced by the string when it vibrates. There are three basic factors that affect the quality of pitch of a string, these are: the tension, the thickness of the string and the length of the string. The higher the thickness of the string, the lower the pitch of the string, thus, increasing the thickness of the string will lower the pitch.

Calculate the mass of chloroform that contains 1.00X10^12 molecules of chloroform

Brums [2.3K]

Molar mass of chloroform (CHCl3)
C = 1 * 12 = 12 a.m.u
H = 1 * 1 = 1 a.m.u
Cl = 3 * 35.5 = 106.5 a.m.u
Molar Mass (CHCl3) = 12 + 1 + 106.5 = 119.5 g / mol

Knowing that: The value of Avogadro's constant corresponds to approximately $6,02*10^{23}$ molecules, if chloroform contains $1,00 * 10^{12}$ molecules. 
We have:

 $1,00 * 10^{12} * 6,02 * 10^{23} = 6,02 * 10 ^ {35} molecules$ 

Now, how many grams are there in the chloroform molecule?

grams -------- molecules
119,5 → $6,02 * 10^{23}$
x → $6,02 * 10^{35}$

$6,02 * 10 ^ {23} * x = 119,5 * 6,02 * 10 ^{35}$
$6,02 * 10 ^ {23}x = 719,39 * 10^{35}$
$x = \frac{719,39}{6,02}*10^{35-23}$
$\boxed{x = 119,5*10^{12}grams}$

A sample of gas in a balloon has an initial temperature of 37C and a volume of 1560 L. If the temperature changes to 82C , and t

FromTheMoon [43]

Answer:

First part: The new volume of the gas is 1786 Liters.

Second part: The temperature required to change the volume of the gas sample is 347 °C

Explanation:

We assume the Charles - Gay Lussac law where, in constant pressure, volume of a gas changes directly proportional to Temperature (in Kelvin)

V1 / T1 = V2/T2

37°C + 273 = 310 K

82°C + 273 = 355 K

1560L / 310°K = V2 / 355K

(1560 / 310) . 355 = V2

1786 L = V2

1560 L / 310 K = 3120 L / T2

T2 = 3120 L . (310 K / 1560 L)

T2 = 620 K

620K - 273 = 347°C
