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

11. you want to calculate the displacement of an object thrown over a bridge. using -10 m/s2 for acceleration due to gravity, what would be the total displacement of the object if it took 8 seconds before hitting the water?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

An alien spaceship is 500 m above the ground and moving at a constant velocity of 150 m/s upwards. how high above the ground is the ship after 5 seconds?
