What is the normal balance side of an asset?

Mademuasel [1]

The normal balance for asset and expense accounts is the debit side, while for income, equity, and liability accounts it is the credit side. An account's assigned normal balance is on the side where increases go because the increases in any account are usually greater than the decreases

One kilogram of water fills a 0.140 m^3 rigid container at an initial pressure of 1.8 MPa. The container is then cooled to 40°C.

Pavel [41]

Answer:

T1 = 299.18 °C

P2 = 0.00738443 MPa

Explanation:

From the data, we can get two properties for the initial condition. These are pressure and specific volume.

The pressure is 1.8 MPa and the specific volume, we can get it with the mass and volume of the container, since it’s filled this is also the volume of the water in it.

$v=\frac{vol (m^{3})}{mass (kg)} = \frac{0.140 m^{3}}{1 kg} = 0.140 \frac{ m^{3}}{kg}$

When we check in the thermodynamic tables, the conditions for saturation at 1.8 MPa we found the following:

$P^{sat} = 1.8 MPa$

$T^{sat} = 207.12 C$

$v_{g} = 0.1103\frac {m^{3}}{kg}$ specific volume for the saturated vapor

$v_{l} = 0.001167 \frac{m^{3}}{kg}$ specific volume for the saturated liquid

Since the specific volume in our condition is higher that the specific volume for the saturated vapor, we have a superheated steam.

Looking in the thermodynamic tables for superheated steam we found that the temperature where the steam has a specific volume of $0.140 \frac{ m^{3}}{kg}$ at 1.8 MPa is 299.18 °C. This is the initial temperature in the container.

Since the only information that we have about the final condition is that the container was cooled. We can assume that it was cooled until a condition of saturation. So, the final pressure for the water will be the pressure of saturation for a temperature of 40°C. From thermodynamic tables we get:

$P^{sat} at 40C = 0.00738443 MPa$

I need answer to this question

blagie [28]

Answer:

1. Graph C

2. Friction

Explanation:

1. The line on all of the graphs shown represents velocity. The formula for velocity is $v=\frac{d}{t}$ where d is distance and t is time. Focusing on the first lap, the starting point on the graph should be the origin and the "ending" point should be (20, 3). These requirements eliminate graph A as an answer because its "end" is not (20, 3). During the break, the student does not move, so the slope of the line should be completely horizontal. The break lasted for 5 minutes, so the correct graph should have a horizontal line between the points (20, 3) and (25, 3). This requirement eliminates graph B and D because their break is either not long enough (B) or too long (D).

2. Friction slows down the movement of objects. When an object is rough, it produces more friction which causes the object to be slowed more. When an object is smooth, friction slows it less than it would for a rough object.
