What are the x, y, and z components of the resulting moment acting on the merry-go-round about the origin?

Curious carl calculated the density of a cube to be 4.50 g/cm3. what is the density of the cube in g/l?

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.)

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
