A scale sits atop a desk. On the scale is a cylindricalcontainer (mass 100g) filled with 200cm3 (200g) ofwater. A hunk of metal (mass 200g, volume 25 cm3)is tied to a string and held suspended in the water.
a) What is the string tension?
b) How many grams does the scale read?
Consider a length of pipe in air. (Take the velocity of sound in air to be 343 m/s.) Calculate the length for a pipe that has a fundamental frequency of 360 HZ if the pipe is open at both ends
Water has a latent heat of vaporization of 2257 kJ/kg. Steam is used to heat a copper tube of 0.358 kg from 21 degrees C to 100 degrees C. All the heating is due to the heat released from the steam condensing. What is the minimum mass of steam that c..
