Consider two vectors A with rightwards harpoon with barb upwards on top equals A subscript x times i with hat on top plus A subscript y times j with hat on top plus A subscript z times k with hat on top and B equals B subscript x times i with hat on top plus B subscript y times j with hat on top plus B subscript z times k with hat on top. Match each of the following expressions for the coefficients of the vector product A with rightwards arrow on top cross times B with rightwards arrow on top with its correct unit vector: - plus open parentheses A subscript y B subscript z minus A subscript z B subscript y close parentheses - minus open parentheses A subscript x B subscript z minus A subscript z B subscript x close parentheses - plus open parentheses A subscript x B subscript y minus A subscript y B subscript x close parentheses
a. i with hat on top
b. k with hat on top
c. j with hat on top

An astronaut in space cannot use a scale or balance to weigh objects because there is no gravity. but she does have devices to measure distance and time accurately. she knows her own mass is 77.4 kg , but she is unsure of the mass of a large gas canister in the airless rocket. when this canister is approaching her at 3.50 m/s , she pushes against it, which slows it down to 1.30 m/s (but does not reverse it) and gives her a speed of 2.60 m/s . what is the mass of the canister?

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.6 m below the tank bottom which is a = 6.7 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute). report your answer in meters to two decimal places.
