I am pretty certain the answer is -60J. Although, I don't feel confident that you can have a negative thermal energy change. @ideasrule- I don't quite understand what you mean?

The denisty of oil is 900kg/m3

Homework Statement The container shown in the figure is filled with oil. It is open to the atmosphere on the left. What is the gauge pressure at point A? Point A is 50cm high from the ground and 50 cm from the top. Homework Equations po+(density)gd The Attempt at a Solution I...

I found the correct equation to use is Eth=Q-Wgas. Alright. Eth=100J-160J = 60 J is that answer required to be in a positive or negative 60J? Thanks, Jared

Homework Statement A gas is compressed from 600cm3 to 200cm3 at a constant pressure of 400kPa . At the same time, 100J of heat energy is transferred out of the gas. What is the change in thermal energy of the gas during this process? Homework Equations Express the answer in Joules...

4.7*105L/s and 1.1*106L/s. 130m wide and 30m deep. The answer needs to be expressed in m/s.

@tiny-tim- Did you come up with an answer of .40m/s where that incportates both rivers? Thanks for your help, Jared

For vfr=4.7*105L/s I used the equation 4.7*105/3900 equals 1.2m/s Thanks for the help. Jared

Homework Statement River Pascal with a volume flow rate of 4.7×105 joins with River Archimedes, which carries 1.1×106 , to form the Bernoulli River. The Bernoulli River is 130 wide and 30 deep. What is the speed of the water in the Bernoulli River? Homework Equations Express your...
