How is sound produced? Key words: Transverse, Longtitudinal, particles
How are standing waves set up in the instruments? Key words: incident, reflected, interference, wavelength, string/pipe length
What factors determine the sound? Key words: frequency, string/pipe length, harmonics, timbre, tension of string, temperature of air
Do the instruments sound different when they play the same note? Needs to be fully explained and link to physics ideas
Do strings and pipes of the same length produce the same fundamental frequency? Again needs to be fully explained with linking to physics ideas.
What is the velocity of 5.5kg object with a force of 2.5N while it reaches 6.0 meters, assuming the velocity at zero meters is zero.
A 28-m3 tank is filled with 2910 moles of an ideal gas. The temperature of the gas is initially 302 K, but it is raised to 740 K. find the change in the pressure of the gas inside the tank
Coulomb's Law gives us an expression for the electric field caused by a point charge with magnitude . Suppose we have several point charges. The electric field at a location is the vector sum of point charge contributions.
A college campus features a large fountain surrounded by the circular pool. Two students start at the northernmost point of pool and walk slowly around it in opposite directions.
A steel wire strung between two supports is initially horizontal when there is no tension on it. When a 9.5 kg painting is hung on the wire, the wire makes a 25° angle to the horizontal, as shown. Illustrate what is the diameter of the wire?
A 0.75 kg ball attached to the end of a horizontal cord, is rotated in a circle of radius 1.9 m on a frictionless horizontal surface, What is the max speed the ball can have
