Which two sentences describe unethical behavior by a scientist? Donnie is a geology researcher at Baxter’s Laboratory in Seattle, Washington. He keeps his lab tidy; he believes that cleanliness and order help avoid expensive accidents that may occur in the lab. Donnie is also very determined; he continues performing an experiment until he reaches the conclusion that he wants and expects. Sometimes, when Donnie is unhappy with how an experiment has turned out, he chooses not to share his findings with the public or his colleagues. But he always makes sure to put on goggles and follow the proper safety procedure before beginning an experiment.

Rank the torques on the five doors shown in the figure above from least to greatest. note that the magnitude of all the forces is the same

Aball is thrown upward. at a height of 10 meters above the ground, the ball has a potential energy of 50 joules (with the potential energy equal to zero at ground level) and is moving upward with a kinetic energy of 50 joules. what is the maximum height h reached by the ball? consider air friction to be negligible. 1. h ≈ 10 m 2. h ≈ 50 m 3. h ≈ 30 m 4. h ≈ 40 m 5. h ≈ 20 m 003 10.0 points which of the two object shown below has the greatest kinetic energy? a m b 1 2 m v 2v 1. kinetic energies are the same. 2. a 3. b 4. unable to determine. 004 10.0 points tim, with mass 74.6 kg, climbs a gymnasium rope a distance of 3.1 m. the acceleration of gravity is 9.8 m/s 2 . how much potential energy does tim gain? answer in units of j. 005 10.0 points a car is moving at 64 miles per hour. the kinetic energy of that car is 5 × 105 j. how much energy does the same car have when it moves at 111 miles per hour? answer in units of j. 006 10.0 points an 102 kg man climbs up a 1 m high flight of stairs. the acceleration of gravity is 9.81 m/s 2 . w
