On the moon, the acceleration due to the effect of gravity is only about 1/6 of that on earth. an astronaut whose weight on earth is 570 n travels to the lunar surface.
(a) what is his weight as measured on the moon? (in newtons)
(b) what is his mass on the moon (in kg)?

In a closed system, the total energy prior to an energy transformation is the total energy after. a. equal to b. unrelated to c. greater than d. less than

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 law of reflection states that the angle of reflection is equal to the angle of
