Quartz, SiO2, contains 46.7% silicon by mass. What mass of silicon is present in 348 g of quartz? You must show your work.

anastassius [24]

Answer:162.516 gm

Explanation:

Given

Quartz contains 46.7 % silicon by mass

i.e.Silicon is 46.7 % by mass

Total mass of Quartz m=348 gm

46.7% of 348 gm

$=\frac{46.7}{100}\times 348=162.516 gm$

You have a string with a mass of 0.0127 kg. You stretch the string with a force of 9.33 N, giving it a length of 1.93 m. Then, y

melomori [17]

Answer:

wavelength = 0.968 m

frequency = 39.02 Hz

Explanation:

given data

mass = 0.0127 kg

force = 9.33 N

length = 1.93 m

to find out

wavelength and Frequency

solution

we know here linear density that is

linear density = $\frac{mass}{length}$ .........1

linear density = $\frac{0.0127}{1.93}$

linear density = 6.5803 × $10^{-3}$ kg/m

wavelength will be here

wavelength = $\frac{2L}{n}$ ..............2

here n = 4 for forth harmonic

wavelength = $\frac{2*1.93}{4}$

wavelength = 0.968 m

and

frequency will be for 4th normal mode of vibration is

frequency = $\frac{4}{2L} \sqrt{\frac{tension}{linear\ density} }$ ..........3

frequency = $\frac{4}{2*1.93} \sqrt{\frac{9.33}{6.5803*10^{-3}} }$

frequency = 1.036269 × 37.654594

frequency = 39.02 Hz
