A vector in the cycle plane had components -14.0 units in the c-direction and 30.0 units in the y-direction. What is the magnitude of the vector?

What is the angle between the vector and the positive x-axis?

The slope of a good speed time indicates ? a. velocity b. acceleration c. direction d. speed

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.)

(a) if the pressure in gas is doubled while its volume is held constant, by what factor do (i) vrms and (ii) change? (b) is it possible to boil water at room temperature (20oc) without heating it? explain.
