Children's height are normal with =36 inches and =2 inches So a child 39.5 inches tall has a standardized height of?
A mixture of unknown salts containing a sulfate salt has been weighed to be 1.50 g. After dissolving the solution in 500 mL of water, heating it, and adding hot barium chloride (40.0 mL, 0.500 M); the precipitate has been collected after succeeding digestion, and the mass was found to be 0.325 g. What is the percentage (by mass) of sulfur in the mixture?
A hovercraft passes point A moving West with a speed of 15 m s−1.
The hovercraft immediately begins to accelerate at a steady rate of 0.13 m s−2 North.
What is the magnitude of the velocity of the hovercraft 200 s after it passes point A? (in m s−1)
Give your answer to 2 s.f.
(note: a hovercraft rides on a cushion of air and so does not contact the ground and experiences no frictional forces)
