A standing wave on a string is given by: y(x, t) = 0.04sin⁡(2πx)cos⁡(100πt), where x and y are in meters and t is in seconds. The left end of the string is located at x = 0. The location of the 5th antinode is at:

The transfer of heat through the movement of a gas or liquid a. convection b. conduction c. radiation
