The wave function for a wave on a taut string is given below, wherex is in meters and t is in seconds. y(x, t) = (0.340 m) sin(10πt -3πx + π/4)
(a) What is the average rate at which energy istransmitted along the string if the linear mass density is 75.0g/m?
W
(b) What is the energy contained in each cycle of the wave?
J
A 512-turn circular-loop coil with a diam- eter of 17.4 cm is initially aligned so that its plane is perpendicular to the Earth’s mag- netic field. In 2.46 ms the coil is rotated 90.0? so that its plane is parallel to the Earth’s magnetic field. An a..
