Air in the atmosphere is heated by the ground this warm air then rises and cooler air falls this is an example of what type of process.
a. convection
b. radiation
c. conduction
d. conductivity
how is conduction different from radiation
a. conduction does not require a physical substance to transfer heat and radiation does.
b. radiation only occurs when two objects are touching and conduction can occur without contact
c. conduction uses currents to transfer heat throughout a fluid and radiation uses electromagnetic waves to carry heat
d. conduction occurs through contact of particles and radiation can occur without the presence of a physical substance

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.)
