A "Standing Transverse Wave" lab set up is made of with string A (mass 0.70-g, length 2.1 m), string B with a liner density four times that of string A, and a block of mass 300-g hanging at the end (Fig. 2). The source outputs sinusoidal waves at 1000 Hz. (a) Find the ratio of the traveling waves' wavelengths on string A and B
(b) If the wave gets 100% transmitted at the conjunction of the two strings, find the two traveling waves along the string and the standing wave equations.
(c) When 10 loops of standing wave pattern is form on string A, what is the weight of the block? At what length that string B would also have integer number of loops on it?

What are the three ways that an object can accelerate

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

You are still fascinated by the process of inkjet printing, as described in the opening storyline for this chapter. you convince your father to take you to his manufacturing facility to see the machines that print expiration dates on eggs. you strike up a conversation with the technician operating the machine. he tells you that the ink drops are created using a piezoelectric crystal, acoustic waves, and the plateau-rayleigh instability, which creates uniform drops of mass m = 1.25 ✕ 10−8 g. while you don't understand the fancy words, you do recognize mass! the technician also tells you that the drops are charged to a controllable value of q and then projected vertically downward between parallel deflecting plates at a constant terminal speed of 20.0 m/s. the plates are ℓ = 2.15 cm long and have a uniform electric field of magnitude e = 6.40 ✕ 104 n/c between them. noting your interest in the process, the technician asks you, "if the position on the egg at which the drop is to be deposited requires that its deflection at the bottom end of the plates be 0.17 mm, what is the required charge on the drop (in c)? " you quickly get to work to find the answer. (neglect the force of gravity.)
