In general the human ear is most sensitive to sounds at 2500 hz. Assuming that sound moves at 330m/s what is the wavelength of s

elena-s [515]

Answer:

0.132 meters is the wavelength of sounds to which people are most sensitive.

Explanation:

Frequency of the sound human ears are most sensitive to = $\nu = 2500Hz=2500 s^{-1}$

Speed of the sound wave = S = 330 m/s

Wavelength of the sound human ears are most sensitive to = $\lambda = ?$

$\nu=\frac{S}{\lambda }$

$2500 s^{-1}=\frac{330 m/s}{\lambda }$

$\lambda =\frac{330 m/s}{2500 s^{-1}}=0.132 m$

0.132 meters is the wavelength of sounds to which people are most sensitive.

The specific heat of water is 4.184Jg ∘C. Determine the final temperature when 600.0 g water at 75.5∘C absorbs 5.90×104 J of ene

sesenic [268]

Answer:

$T_2=98.5^{\circ}$

Explanation:

Given that,

The specific heat of water is 4.184Jg°C

Mass, m = 600 g

Initial temperature, T₁ = 75.5°C

We need to find the final temperature. We know that heat absorbed is given by :

$Q=mc\Delta T\\\\Q=mc(T_2-T_1)\\\\\dfrac{Q}{mc}=(T_2-T_1)\\\\\\T_2=\dfrac{Q}{mc}+T_1\\\\T_2=\dfrac{5.9\times 10^4}{600\times 4.184}+75\\\\T_2=98.5^{\circ}$

So, the final temperature is equal to $98.5^{\circ}$ .

Describe two types of mechanical weathering

Nuetrik [128]

The 2 types of mechanical weathering are .....
1) * Temperature Change
-Temperature change makes rocks contract and expand
-Also one of the important cause of mechanical weathering.
2) * Abrasion
-Abrasion is a process in which an external force
Example: water movement or gravity which causes rock materials grind (reduce <<< synonyms) which can break apart the outer layers of affected rocks.*PLEASE GIVE THIS A THANKS :) :D xD AND ALSO THE BRAINIST ANSWER PREETTY PLEASEEEEEEEE, DON'T YOU EVER FEEL LIKE YOUR GOOOOING TO GIVE ME THE BRAINIEST ANSWER/CROWN??? xD
