Two loudspeakers are 1.00m apart. a person stands 4.00m from one speaker. how far must this person be from the second speaker to detect destructive interference when the speakers emit an 115Hz sound? assume the temperature is 20°C.​

Find the volume of the ellipsoid x^2+y^2+5z^2=36.

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.)

Explain why electric current cannot exist if a current doesn't have a voltage source.
