Willy the great white shark swims in the ocean hunting for his favorite meal, seals! He swims 200 m N, 150 m E, 100 m S, 500 m W, 100 m S, 200 m E, 150
m N over the course of 8 hours. Make a sketch of the journey and determine the
following:
What was Willy's total distance in meters traveled at the end of the trip?

Aball is thrown straight up into the air with a speed of 21 m/s. if the ball has a mass of 0.1 kg, how high does the ball go? acceleration due to gravity is g = 9.8 m/s^2. a. 22.5 m b. 20.0 m c. 25.0 m d. 17.5 m

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.

Which of the following bonds would be most polar? a. c-i b. c-br c. c-cl d. c-f e. c-o
