The lowest note on a violin string makes a 196 Hz (G below middle C) note. If this is the fundamental frequency for the string, how long is the string? What estimate do you need to make?
In a physics lab experiment, a student immersed 207 one-cent coins (each having a mass of 3.00 g ) in boiling water. What was the final temperature of the coins
Two stationary positive point charges, charge 1 of magnitude 3.45 nC and charge 2 of magnitude 1.50 nC, are separated by a distance of 52 cm. An electron is released from rest at the point midway between the two charges, and it moves along the lin..
