One end of a horizontal rope is attached to a prong of anelectrically driven tuning fork that vibrates at 120 hz. the otherend passes over a pulley and supports a 1.70 kg mass. the linear mass density of the rope is0.0590 kg/m.(a) what is the speed of a transverse wave onthe rope? v1.70 kg =1 m/s(b) what is the wavelength? λ1.70 kg =2 m(c) how would your answers to parts (a) and (b) be changed if themass were increased to 2.80 kg? v2.80 kg = 3v1.70 kgλ2.80kg = 4λ1.70 kg

The membrane surrounding a living cell consists of an inner and an outer wall that are separated by a small space. assume that the membrane acts like a parallel plate capacitor in which the effective charge density on the inner and outer walls has a magnitude of 7.0 × 10-6 c/m2. (a) what is the magnitude of the electric field within the cell membrane? (b) find the magnitude of the electric force that would be exerted on a potassium ion (k+; charge = +e) placed inside the membrane.

Astudent is given an assignment to demonstrate diffraction. he takes a photograph of a straw in a glass of water. the straw appears bent at the water level. which best describes this example? a) this is a good example of diffraction. b) this is an example of dispersion and not diffraction. c) this is an example of refraction and not diffraction. d) this is an example of reflection and not diffraction.
