Auniform disk with mass m = 8.88 kg and radius r = 1.3 m lies in the x-y plane and centered at the origin. three forces act in the +y-direction on the disk: 1) a force 335 n at the edge of the disk on the +x-axis, 2) a force 335 n at the edge of the disk on the –y-axis, and 3) a force 335 n acts at the edge of the disk at an angle θ = 33° above the –x-axis.
1) what is the magnitude of the torque on the disk about the z axis due to f1?
2) what is the magnitude of the torque on the disk about the z axis due to f2?
3) what is the magnitude of the torque on the disk about the z axis due to f3?
4) what is the x-component of the net torque about the z axis on the disk?
5) what is the y-component of the net torque about the z axis on the disk?
6) what is the z-component of the net torque about the z axis on the disk?
7) what is the magnitude of the angular acceleration about the z axis of the disk?
8) if the disk starts from rest, what is the rotational energy of the disk after the forces have been applied for t =1.5s?

What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? (2 points) as air pressure in an area increases, the density of the gas particles in that area decreases. as air pressure in an area increases, the density of the gas particles in that area increases. as air pressure in an area increases, the density of the gas particles in that area remains constant. as air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. 3. which of the following correctly describes a way in which earth's atmosphere interacts with the geosphere? (2 points) it contains gases that living organisms breathe. it contains gases that trap incoming solar radiation. it provides a medium for cycles that provide nutrients to living organisms. it provides a medium for water to move between earth's surface and the air. 4. which of the following is considered a drawback to using wind energy as a source of power? (2 points) wind energy is nonrenewable. wind energy produces large amounts of air pollution. wind turbines can kill birds that fly through the rotors. wind turbines are built too close to major population centers. 5. a meteorologist predicts that the weather in a region will soon change from clear skies to probable thunderstorms. prior to making this prediction, what did the meteorologist most likely observe on a barometer? (2 points) the barometer fell slightly. the barometer fell substantially. the barometer rose slightly. the barometer rose substantially. 6. which of the following do meteorologists not typically use weather balloons to record? (2 points) atmospheric pressure cloud types humidity temperature 7. during which step in the can crush lab did water vapor force air from the can? (2 points) the can was filled nearly to the top with water. the can was placed on the hot stove top burner for several minutes. the can was removed from the hot stove top burner. the can was placed upside-down in the water-filled pan.
