How you got the answer:

-- Either you guessed, or else you asked somebody else and they gave you the answer.  It really doesn't matter.  As you can see, whichever it was, you didn't learn anything in the process.

The helpful and correct way to solve the problem:

-- For any wave, <em>Speed = (frequency) x (wavelength)</em>

Whenever you're dealing with waves, and you know any two of those three quantities, you can always use this formula to calculate the quantity you don't know.

This problem GIVES you the speed and the wavelength.  USE this formula to calculate the frequency.

A wave will go faster through a liquid at ____________ temperatures
cupoosta [38]
<h3><u>Answer;</u></h3>

Higher temperatures

A wave will go faster through a liquid at <em><u>highe</u></em><u>r </u>temperatures

<h3><u>Explanation;</u></h3>
  • <em><u>Mechanical waves are types of waves that require a material medium for transmission.</u></em> An example of mechanical wave is the sound wave whose transmission occurs in medium such as solids, liquids and gases.  
  • <em><u>The transmission of mechanical waves involves vibration of particles through the medium of transmission, thus transfer of energy from one point to another. </u></em>The vibration of particle may be in the form of a longitudinal wave or a transverse wave.  
  • <em><u>Increasing the temperature in a medium increases the kinetic energy of the particles in the medium and thus increasing the speed at which the particles vibrates and thus aiding a faster transmission of a wave.</u></em>

Hey guys, i'm at 10 grade at school i have a physics question about stress tension and young modulus ? Please this is my questio
makvit [3.9K]
Use the eq. of Young modulus Y=(F/A)/(∆l/lo)
dimana ∆l is the elongation of wire, lo is its initial length.
So ∆l = (F/A)lo/Y.
∆l = (1000N/(6.5 × 10^-7 m^2))×(2.5m)/(2.0 × 10^-11 N/m^2)
Use calculator to finish it.
