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 airI then have to compare and contrast:
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.
The human body converts internal chemical energy into work and heatat rates of 60 to 125 W (called the basal metabolic rate). Thisenergy comes from the food we eat and is usually measured inkilocalories = 4.184 kJ
Two masses are joined together by a rod with a uniform linear mass density of 400 grams per meter, What is their angular momentum
Alan leaves Los Angeles at 8:00 a.m to drive San Francisco, 400 mi away. He travels at a steady 50 mph. find Who gets to San Francisco first
A thin stick is placed along the x axis so that one of its ends is at x1 = 0.00 m and the other one at x2 = 1.35 m. The stick has a non-uniform mass density ?(x) = ax b, where a = 0.349 kg/m2 and b = 0.317 kg/m. What is the coordinate of the center o..
Two parallel, uniformly charged, infinitely long wires carry opposite charges with a linear charge density ? = 2.15 ?C/m and are 6.69 cm apart. What is the magnitude of the electric field at a point midway between them and 54.3 cm above the plane ..
A 5 kg mass attached to a horizontal spring is pulled from its equilibrium position by 4 m and let go. find is the maximum velocity of the mass
Calculate the force required to pull a copper ball of radius 3.00 cm upward through a fluid at the constant speed 6.00 cm/s
A ball of mass M = 17 kg is suspended from a vertical inextensible string of length l = 1.5 m. A bullet of mass m = M/2 traveling with a horizontal velocity v = 9sqrt(g*L) collides with the ball, What is the velocity of the ball-bullet system
Assuming the density of seawater is 1.03 g/cm3, find the total weight of water on top of a nuclear submarine at a depth of 155 m, what water pressure would a diver experience at this depth
Suppose current is flowing in a wire from right to left. Which way do the electrons in the wire move? If three identical bulbs are connected in series across a 12V battery, the voltage across each bulb will be?
A duck has a mass of 2.1 kg. As the duck paddles, a force of 0.09 N acts on it in a direction due east, Find the magnitude and direction (relative to due east) of the displacement that the duck undergoes in 2.6 s while the forces are acting
