A standard violin string is 32.8 cm long from the tuning peg to the bridge. When played open(without pressing a finger against the fingerboard), this string has a fundamental (lowest)frequency of 440 Hz.
(a) What is the wavelength of the wave at this frequency? (Hint: the lowest frequency is alsothe longest wavelength that can produce a standing wave.) b.
(b) What is the speed of the wave on the string? (Hint: this is not the speed of sound!)c.
(c) How far from the end of the string should a finger be placed in order to produce afundamental frequency of 523 Hz.
How much work must be done to bring three electrons. calculate the mass of an ice cube.
Compute the density of entropically raised element of air
Estimate the power radiated by the human body. Be sure to state the estimated values of all relevant quantities. You need only outline your calculations. How does this value compare with the average caloric intake for humans?

Determine the magnitude of the emf induced in the loop after exactly time 6 has passed since the circumference of the loop started to reduce.
With two resistors of resistances of 16(ohms) and 24(ohms) are connected in parallel. Find the equivalent resistance of the network, and the current in each resistor
A 77 person stands on the uniform ladder 4.0 long, that weighs 100. The floor is rough; hence, it exerts both a normal force, and a frictional force, on the ladder. The wall, on the other hand, is frictionless; it exerts only the normal force.
Illustrate what was the magnitude of the centripetal acceleration of the rock when it was on the string? (b) What was its speed when it was on the string?
