Homework Statement A basketball player does 2.43 X 105 J of work during her time in the game, and evaporates 0.110 kg of water. Assuming latent heat of 2.26 X 106 J/kg for the perspiration (the same as for water), (a) determine the change in the player’s internal energy, and (b) the number...

I am not sure what you are trying to ask. I need to know h. But in order to find h i need a way to find P2. I don't know how to start the problem.

Homework Statement A submarine called the Deep View 66 is currently being developed to take 66 tourists at a time on sightseeing trips to tropical coral reefs. According to guidelines of the American Society of Mechanical Engineers (ASME), to be safe for human occupancy the Deep View 66...

Thank you. That really helped

Here is the question again. I don't understand it? A 67 {\rm kg} person sits on a 3.6 {\rm kg} chair. Each leg of the chair makes contact with the floor in a circle that is 1.4 {\rm cm} in diameter. Here is what they want me to find - Find the pressure exerted on the floor by each leg of...

It doesn't say how many legs the chair has. So I believe we should assume that the chair has 4 legs

Homework Statement A 67 kg person sits on a 3.6 kg chair. Each leg of the chair makes contact with the floor in a circle that is 1.4 cm in diameter.Homework Equations p= M/V P= F/A Pg = P - Pat Pat = 1.01 x 105 N/m2The Attempt at a Solution I figured out the area of the circle using the pi r...

still i don't get it, if the theoretical yeild of NH3 is 2 mol and the limiting reagent is H2 how is that suppose to work i don't get it.

I believe the reagent is N2 (that's N and the subscript 2)

Let me ask u another question Theoretically, how many moles of NH3 will be produced I believe it's 2 Moles of NH3 because that's how many there are in the balanced equation. Is it right if so How should i get the actual yield of NH3 if the percent yield is 80%, how many moles of NH3...

6.0 moles of N2 that's are mixed with 12.0 moles of H2 according to the following equation: The equation is already balanced: N2(g)+ 3H2(g) yields 2NH3 (g) The questions asks for what is the chemical in excess? is it H2 or N2 I solved the problem but i want to make sure if it is right...

idk if i did this correctly so far so here goes. The question states A large rubber ball (8.80 kg) is fired straight down from the roof of a building from a spring loaded mechanism that stored 987 J of elastic potential energy. The building roof is 14.0 meters above ground. The rubber...

i got that but i need the formula though

well i don't have the velocity to use the kinetic energy formula u got any advice for that.
