Answer:
Total pressure exerted at bottom = 119785.71 N/m^2
Explanation:
given data:
volume of water in bottle = 150 L = 0.35 m^3
Area of bottle = 2 ft^2
density of water = 1000 kg/m
Absolute pressure on bottom of bottle will be sum of atmospheric pressure and pressure due to water
Pressure due to water P = F/A
F, force exerted by water = mg
m, mass of water = density * volume
= 1000*0.350 = 350 kg
F = 350*9.8 = 3430 N
A = 2 ft^2 = 0.1858 m^2
so, pressure P = 3430/ 0.1858 = 18460.71 N/m^2
Atmospheric pressure
At sea level atmospheric pressure is 101325 Pa
Total pressure exerted at bottom = 18460.71 + 101325 = 119785.71 N/m^2
Total pressure exerted at bottom = 119785.71 N/m^2
Answer:
Answer for question "
The specific heats of aluminum and iron are 0.214 and 0.107 calories per gram degrees Celsius [cal/(g degrees Upper C )] respectively. If we add the same amount of energy to a cube of each material (of the same mass) and find that the temperature of the aluminum increases by 28 degrees Fahrenheit [degrees Upper F ], how much will the iron temperature increase in degrees Fahrenheit [degrees Upper F ]? "
