- A room measures 121⁄2 feet wide and 151⁄2 feet long. The walls are 8 feethigh. The volume of air in the room changes six times each hour. How manycubic feet of air enters the room each minute?the specific heat (cp or cv) can also be understood as a "capacity or ability of a given material to store "heat". In this way, we can say that: 1- the greater the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material.2- the higher the specific heat, the lower the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material3- the lower the specific heat, the greater the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material4- the lower the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change5-the higher the specific heat, the amount of "heat" needed to cause an increase or decrease in temperature per unit mass of the material does not change choose only one of the above alternatives as correctIf a certain gasoline weighs 7kN/m^3 , what are the values of its density, specific volume, and specific gravity relative to water?
- The gravitational constant g is 9.807 m/s2 at sea level, but it decreases as you go up in elevation. A useful equation for this decrease in g is g = a – bz, where z is the elevation above sea level, a = 9.807 m/s2, and b = 3.32 × 10–6 1/s2. An astronaut “weighs” 80.0 kg at sea level. [Technically this means that his/her mass is 80.0 kg.] Calculate this person’s weight in N while floating around in the International Space Station (z = 354 km). If the Space Station were to suddenly stop in its orbit, what gravitational acceleration would the astronaut feel immediately after the satellite stopped moving? In light of your answer, explain why astronauts on the Space Station feel “weightless.”Calculate the pressure due to a column of 0.4 m of the following liquids (a) water (b) an oil of specific gravity 0.9 (c) mercury (d) a liquid of specific weight 46780 N/mHydrostatic pressure at any given depth of a liquid depends on the_____ of the container.a)Volumeb)ShapeC)Depthd)All of the above .As the temperature of oil increases, the viscosity of oil willa) increaseb) decreaseC)not change Which of the following units would NOT be used for volume flow rate?a) gal/minb) Ib/sc)m⅗d)ft^3/s 2.Dynamic viscosity is defined as,a) weight per unit volume of a fluidb) volume per unit weight of a fluidc) the velocity gradient divided by the shearing stress of a fluidd)the shearing stress divided by the velocity gradient of a fluid
- Need complete answer ASAP... An object is submerged below the surface of the sea with an exerted pressure of 99.92 bar. How deep is the object submerged? The density of sea water is 1020kg/m3, the gravitational force is 9.7 m/s2, and the atmospheric pressure is 0.98 bar.Emperor penguins dive deeper into sea water than any other bird. An Emperor penguin weighing 245 newtons [N] can dive to a maximum depth of 450 feet [ft] below the surface of the sea water. The volume of an Emperor penguin can be modeled as a cylinder with a diameter of 0.25 meters [m] and a height of 1.1 meters [m]. The specific gravity of sea water is 1.027. Find the total pressure acting on the penguin at the maximum depth in units of atmospheres [atm].The gravitational acceleration on Mars is 3.72 m/s2. The density of water is 1000 kg/m3. Starting from these assumptions, estimate the specific weight of water on Mars in lbf/ft3. Note that when converting lbm (pounds mass) to lbf (pounds force), a unit conversion called gc is required (1 lbf = 32.2 lbm ft s-2). The conversion factor ensures that (under normal gravity), a 100 lbm load generates 100 lbf of gravitational force
