A standing wave has the following wave-function: y(x. t) = 0.2 sin(310) cos(127). where x and y are in meters, and t is in seconds. If the length of the string is L=2
mand it is fixed at both ends, then the harmonic, n, in which the string is
vibrating is

Determine the maximum r-value of the polar equation r =3+3 cos 0

True or false when elements combine to form a mixture, the resulting chemical properties may be very different from those of the elements that make it.

Asmall object with mass 0.200 kg swings back and forth on the lower end of a light rope that is 3.00 m long. the upper end of the rope is attached to the ceiling. as the object swings through its lowest position, where the rope is vertical, the speed of the object is 5.80 m/s. at this point in the motion, what is the tension in the rope? (use g = 9.80 m/s2.)
