A rectangular vessel measurements 5 cm by 15 cm. Ethanol of density p = 810 kg. m-3a) calculate is poured into the vessel to a depth of 5.5 cm [the density of water is 1000 kgm-3, atmospheric pressure is 101300 pa] i. the pressure due to the ethanol

iii the total pressure of the liquid on the base of the container

iii. the force ethanol exerts at the botton the tank

b) determine the relative density of ethanol​

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter

Astronomers studying the planet of rhombus have detected sedimentary rock on its surface. one astronomer wonders if material in this sedimentary rock used to be in igneous rock deep in rhombus’s interior. can igneous rock become sedimentary rock? explain your answer.
