The diagram shows a tank that is filled with oil. the density of the oil is 920kg/m³. a. calculate the volume of the tank from the dimensions shown in the diagram. (2,0m×1,5m×1,0m)
b. calculate the weight of the oil in the tank
c. the pressure on the bottom of the tank is caused by the weight of the oil. calculate the pressure using P=F/A

Yup no bull frogs here man

Imma say go with a (:

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
