You're outside on a cold day (tout = 0 °c)listening to your ipod with an external circular speaker having a diameter 0.0550 m. because of the cold you decide to go inside where the temperature is 27.5 °c. if your favorite song begins with a 8.54-khz tone, find the change in the diffraction angle of this tone assuming the air behaves as an ideal gas.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
