100 kg of R-134a at 280 kPa are contained in a piston-cylinder device whose volume is 8.672 m3. The piston is now moved until th

e volume is one-half its original size. This is done such that the pressure of the R-134a does not change. Determine the final temperature and the change in the total internal energy of the R-134a. (Round the final answers to two decimal places.)

If you want to play a tune on wine glasses, you’ll need to adjust the oscillation frequencies by adding water to the glasses. Th
jonny [76]

Answer:Reducing mass i.e. water

Explanation:

Frequency For given mass in glass is given by

f=\frac{1}{2\pi }\sqrt{\frac{k}{m}}

where k =stiffness of the glass

m=mass of water in glass

from the above expression we can see that if mass is inversely Proportional to frequency

thus reducing mass we can increase frequency

When comparing an x-ray to a radio wave, what should you look for to determine which formula represents the x-ray?
asambeis [7]

Answer:

D. A low lambda, λ, and a high nu, ν

Explanation:

  • Both x-rays and radio waves are electromagnetic waves that are part of the electromagnetic spectrum.
  • <em><u>Radio waves have the longest wavelengths in the electromagnetic spectrum and the lowest frequency.</u></em>
  • X-rays on the other hand <em><u>have a higher frequency compared to radio waves and a lower wavelength than that of the radio waves</u></em>.
  • All electromagnetic waves in the electromagnetic waves travel with a speed of light, 3.0 × 10^8 m/s. They also posses energy given by the formula E = hf, where h is the plank's constant.
