Gravity is affected by the (1 point) 1. charge of the objects and whether the charges are the same or opposite 2. force applied to the object when moving 3. mass of the objects and the distance between two objects 4. the size of the objects and the difference in charge

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.)
