A vertical circular cross-sectional jet of air strikes a conical deflector as shown in Figure H. A vertical anchoring force of 0.1N is required to hold the deflector in place. Determine the mass [kg] of the deflector. The magnitude of velocity of the air remains constant. Neglect gravity of air as well as pressure differences.

A typical sugar cube has an edge length of 1 cm. If you had a cubical box that contained a mole of sugar cubes, what would its edge length be?

The quantity of energy Q transferred by heat conduction through an insulating pad in time interval Δt is described by Q/Δt = κAΔT/d, where κ is the thermal conductivity of the material, A is the face area of the pad (perpendicular to the direction of heat flow), ΔT is the difference in temperature across the pad, and d is the thickness of the pad. In one trial to test material as lining for sleeping bags, 86.0 J of heat is transferred through a 3.40-cm-thick pad when the temperature on one side is 37.0°C and on the other side is 2.00°C. In a trial of the same duration with the same temperatures, how much heat will be transferred when more of the material is added to form a pad with the same face area and total thickness 8.41 cm?

Imagine you are in line to enter a brand new shopping mall and you are very much excited because after months of waiting, you will now be able to enter shopping malls after the pandemic. The stores comprising the mall are very popular. These stores include Converse, Gucci, Jansport, Fendi and all other popular brands, and so the demand to enter is very high. Security guards only allow one person through the doors at a time. As a result, the line and the wait are quite long. To add to the chaos, the waiting crowd is made mostly of frequent shoppers who are growing very impatient and holding up the line with their constant complains. Together, these factors affect the flow of customers into the shopping mall, just as electric resistance affects the flow of charges through a current. 1. What makes less resistance favorable in a circuit? 2.If the guard formed two adjacent lines to allow two people into the mall at a time, we would expect the mall to be filled up faster. If we encased these…

Heat Q, which has the SI unit of joule (J), is the quantity in mechanical engineering that describes the transit of energy from one location to another. The equation for the flow of heat during the time interval At through an insulated wall is KAAT Q = (Тh — T) where k is the thermal conductivity of the material from which the wall is made, A and L are the wall's area and thickness, and Th – T; is the difference (in degrees Celsius) between the high- and low-temperature sides of the wall. By using the principle of dimensional consistency, what is the correct dimension for thermal conductivity in the SI? The lowercase Greek character kappa (K) is a conventional mathematical symbol used for thermal conductivity. Appendix A summarizes the names and symbols of Greek letters. О a. (W-m)/°C O b. °C/(W. m) O c. (m . °C)/W O d. W/(m . °C)

Scientists are studying the temperature on a distant planet. They find that the surface temperature at one location is 25° Celsius. They also find that the temperature decreases by 3° Celsius for each kilometer you go up from the surface. Let T represent the temperature (in Celsius), and let H be the height above the surface (in kilometers). Write an equation relating T to H, and then graph your equation using the axes below. * T axis (y) goes up to 30 (counting by 5's)  * H axis(x)  goes up to 8 (counting by 1's)  **Be sure to write out the points too

When a body is heated, how fast the temperature of the body changes depends on the material. The thermal energy needed to change the temperature of a body by AT' is determined by the equation AQ = mcAT where AQ is the thermal energy, c is the specific heat of the material, and m is the mass of the body. The specific heat is the thermal energy needed to raise the temperature of 1 gram material by one degree. If a hot metal block is put into cold water in a container, the metal block will be cooled, and the water and the container will be warmed. Eventually, the system will be at a final temperature when thermal equilibrium is reached. The process can be expressed as Heat gained = Heat lost [Heat Gained by the container and water] = [Heat lost by the metal block] The initial temperature T; of the water and the container, the initial temperature of the metal block TB, the final temperature of the system Tf, the specific heat of the container, and the specific heat of the metal block are…
