Will mark brainilest and I will give 5 stars: Part A: A ball of mass ,3.5kg rolls all the way down a slope inclined at 40∘ to the horizontal, with a base of length 4.8m. How much GPE does the ball lose?

Part B: If the average frictional forces are 4.0N, work out how much work the ball does against friction.

True or false: the cycle of seasons on the earth is caused by the tilt of the earth on its axis toward and away from the sun.

The material that keeps its new shape after it is stretched is called?

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.)
