Why do we see the color black?

Answers

We see black colour in absence of light. Black colour absoorbs all the light, ( just opposite of white) and hence we do not see any colour. Black colour is also related to darkness.

Which two of the following are the densest of the materials shown?Material Mass (g) Volume (L)
Rock 1000 0.5
Pillow 200 10
Bottle of soda 2000 2
Loaf of bread 100 1

Answers

Answer:

The densest materials are rock and bottle of soda.

Explanation:

The density of material is given by,

Density = (mass)/(volume)

Case 1: Rock

Density = (1000)/(0.5)

Density = 2000 (g)/(L)

Case 2: Pillow

Density = (200)/(10)

Density = 20 (g)/(L)

Case 3: Bottle of soda

Density = (2000)/(2)

Density = 1000 (g)/(L)

Case 4: Load of bread

Density = (100)/(1)

Density = 100 (g)/(L)

The densest materials are rock and bottle of soda.

A trumpet creates a sound wave that has a wave speed of 350m/s and a wavelength of 0.8 m . What is the frequency of the sound wave

Answers

Answer:

The frequency of sound wave created by trumpet is 437.5Hz

Explanation:

Given

the speed of sound wave = 350 ms^(-1)

the wavelength of sound wave = 0.8 m

the frequency of sound wave = ?

All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:

v = fλ, where

v is speed of the wave

f is frequency of the wave

λ is wavelength of the wave

therefore frequency of sound wave is given by

f = v/λ

 = 350ms^(-1)/0.8m

 = 437.5s^(-1)

 = 437.5Hz (since 1 s^(-1) = 1 Hz (Hertz)

Hence the frequency of sound wave created by trumpet is 437.5Hz

Answer:

The frequency of sound wave created by trumpet is 437.5Hz

Explanation:

Given

the speed of sound wave = 350 m

the wavelength of sound wave = 0.8 m

the frequency of sound wave = ?

All the waves have same relationship among wavelength, frequency and speed, which is given by the equation:

v = fλ, where

v is speed of the wave

f is frequency of the wave

λ is wavelength of the wave

therefore frequency of sound wave is given by

f = v/λ

= 350m/0.8m

= 437.5

= 437.5Hz (since 1  = 1 Hz (Hertz)

Hence the frequency of sound wave created by trumpet is 437.5Hz
