A hula hoop of 1.40 m diameter rolls from rest down an incline whose elevated end is 2.50 m above a flat section. WIth what angular speed, in rad/s, is a point on the hula hoop spinning when it reaches the flat section

If 2 moles of co_2 at 2l and 500k are expanded reversibly to 20l, more work can be obtained from an adiabatic process than from an isothermal process. is the above statement true or false?

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.)

If a simple machine reduces the strength of a force, what must be increased?
