2.W23=0

3.-3*p0*V_0

4.0

5=W=6PoVo

6. T3 = 4/3T1

Explanation:

Work Integral in the pV Plane

The diagram shows the pressure and volume of an ideal gas during one cycle of an engine. As the gas proceeds from state 1 to state 2, it is heated at constant pressure. It is then cooled at constant volume, until it reaches state 3. The gas is then cooled at constant pressure to state 4. Finally, the gas is heated at constant volume until it returns to state 1.

The preamble above should precede, the questions:

1.Find w12, the work done on the gas as it expands from state 1 to state 2.

Express the work done in terms of Po and Vo

= W=PdV

3Po(4vo-1v0)

9*Po*Vo

2.Find W23 , the work done on the gas as it cools from state 2 to state 3.

Express your answer in terms of Po and Vo.

W23=0 becuase volume is constant , so no work is done

C) Find W34, the work done on the gas as it is compressed from state 3 to state 4.

Express your answer in terms of Po and Vo=

-3*p0*V_0

D) Find W41, the work done on the gas as it is heated from state 4 to state 1.

Express your answer in terms of Po and Vo

W=0 volume is constant

E) What is Wnet, the total work done on the gas during one cycle?

Express your answer in terms of Po and Vo ..

W=6PoVo

F. When the gas is in state 1, its temperature is T1. Find the temperature T3 of the gas when it is in state 3. (Keep in mind that this is an ideal gas.)

Express T3 in terms of T1.

T3 = 4/3T1

1 is a answer of a question

Answer from: Quest

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem. $\begin{aligned} | \vec{v}| & = \sqrt{(\text{2.7 m/s})^2 + (\text{1.2 m/s})^2 } \\ & = 2.954 \text{ m/s} \end{aligned}$ to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

An electron and a proton have the same kinetic energy upon entering a region of constant magnetic field and their velocity vectors are perpendicular to the magnetic field. suppose the magnetic field is strong enough to allow the particles to circle in the field. note: you'll need to look up the masses for an electron and proton. 1) what is the ratio of the radii of their circular paths rp/re?

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
