Three moles of an ideal gas expand at a constant pressure of 4 x 105 Pa from 0.020 to 0.050 m3. What is the work done by the gas? Select one: a. 1.2 x 104J b. 2.1 x 104 J c. 3.5 x 104 J d. 4.2 x 104 J

Answers

Answer 1

The correct option is a. The work done by the gas is 1.2 x 10^{4} J.

To calculate the work done by an ideal gas during a constant pressure expansion, we use the formula W = P * ΔV, where W represents work, P is the constant pressure, and ΔV is the change in volume. In this case, P = 4 x 10^{5} Pa, and ΔV = 0.050 m^{3} - 0.020 m^{3} = 0.030 m^{3}. Plugging these values into the formula, we get W = (4 x 10^{5} Pa) * (0.030 m^{3}), which results in W = 1.2 x 10^{4} J. Therefore, the work done by the gas is 1.2 x 10^{4} J, and the correct option is a.

Calculation steps:
1. Determine ΔV: ΔV = 0.050 m^{3} - 0.020 m^{3} = 0.030 m^{3}
2. Apply the formula W = P * ΔV: W = (4 x 10^{5} Pa) * (0.030 m^{3})
3. Calculate W: W = 1.2 x 10^{4} J

list 10 uses of metals​

Answers

Answer:

Shiny metals such as copper, silver, and gold are often used for decorative arts, jewelry, and coins.

Strong metals such as iron and metal alloys such as stainless steel are used to build structures, ships, and vehicles including cars, trains, and trucks.

Some metals have specific qualities that dictate their use. For example, copper is a good choice for wiring because it is particularly good at conducting electricity. Tungsten is used for the filaments of light bulbs because it glows white-hot without melting.

Nonmetals are plentiful and useful. These are among the most commonly used:

Oxygen, a gas, is absolutely essential to human life. Not only do we breathe it and use it for medical purposes, but we also use it as an important element in combustion.

Sulfur is valued for its medical properties and as an important ingredient in many chemical solutions. Sulfuric acid is an important tool for industry, used in batteries and manufacturing.

Chlorine is a powerful disinfectant. It is used to purify water for drinking and fill swimming pools.

12) Two-point charges each have a value of 3.0 C and 5.0 C and are separated by a distance of 6.0 m. What is the electric field at a point midway between the two charges?

Answers

Answer:

The electric field at a point midway between the two charges is 2 x 10⁹ N/C.

Explanation:

Given;

first point charge, Q₁ = 3.0 C

second point charge, Q₂ = 5.0 C

distance between the two point charges, R = 6.0 m

The mid-point between the two charges, r = R/2 = 3.0 m

3.0 C <-------------------->3.0m<----------------------->5.0 C

The forces are acting in opposite direction, the electric field strength of each charge is calculated as;

[tex]E_1 = \frac{kQ_1}{r^2} (-\bar x)\\\\E_1 = \frac{9\times 10^9 \times 3}{3^2}(-\bar x)[/tex]

[tex]E_2 = \frac{kQ_1}{r^2} (+\bar x)\\\\E_2 = \frac{9\times 10^9 \times 5}{3^2} (+\bar x)\\\\[/tex]

The net electric field is calculated as;

[tex]E_{net} = \frac{9\times 10^9 \times 5}{3^2} \ - \ \frac{9\times 10^9 \times 3}{3^2}\\\\E_{net} = \frac{9\times 10^9 }{3^2} (5-3)\\\\E_{net} = 2 \times 10^9 \ N/C[/tex]

Therefore, the electric field at a point midway between the two charges is 2 x 10⁹ N/C.

do you weigh yourself regularly?what the things you do to adjust if your weight starts to slip upward or downward?​

Answers

Answer:

start a healthy diet. But starting a healthy diet doesn't mean only eating greens, you should minimize the amount of regular food you take and eat a balanced diet.

Weight is the measure of the mass of the body. Mass is the amount of matter a body contains.

Personally, I do weigh myself regularly in order to determine the action to take if the weight either slips upward or downwards.

If the weight slips upward, what I do is to reduce the amount of calorie intake and also exercise. Reduction in calorie intake and regular exercise can drastically reduce the weight of a body considerably.

If otherwise, I ensure I regularly consume a balanced diet and energy-giving foods.

How do you know that Earth is affected by the gravitational pull of the sun ? Explain how you would be affected if you were able to safely move farther and farther away from Earth . Support your ideas

Answers

Answer:

The Sun's gravity pulls on the planets, just as Earth's gravity pulls down anything that is not held up by some other force and keeps you and me on the ground.

Explanation: Newton realized that the reason the planets orbit the Sun is related to why objects fall to Earth when we drop them. I am so sorry if I get this wrong, I'm in 5th grade! ♥

The Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

The Earth is continuously orbiting around the Sun, that is why we are experiencing the day and night everyday. And this orbiting is caused by the gravitational full by Sun on Earth, which is given as,

[tex]F = \dfrac{G \times M \times M'}{R^{2}}[/tex]

Here, G is the universal gravitational constant, M is the mass of Earth and M' is the mass of Sun. And R is the distance between the Earth and Sun.

If we suppose to move farther and farther away from the Earth then the strength of gravitational pull by Earth will decrease with the increasing distance. Because the gravitational pull is inversely proportional to square of distance.

Thus, we can conclude that the Sun provides rotational motion to Earth by gravitational pull and if we get farther and farther, we will experience decreased gravitational force.

Bronco the skydiver, whose mass is 80 kg experiences 200 N of air resistance and gravity pulls on him with 800 N. The acceleration of his fall  7.5 m/sec².

What is force?

A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.

To find the acceleration,

   F = mg

   F = 80.(10)

   F = 800 N

   air resistance = 200 N

   Net force = F - air resistance

                = 800 - 200

                =  600 N

   600 = mass . acceleration

   600 = 80 . acceleration

   acceleration = 7.5 m/sec²

Acceleration is inversely proportional to the net force

if acceleration goes up forces goes down

if acceleration goes down mass goes down

Answer:

Acceleration is directly proportional to the net force

Explanation:

The net force acting on an object is given by :

F = ma

Where

m is mass

and

a is acceleration

It can be seen that the relation between the net force and the acceleration is direct i.e. as the acceleration increases, the net force will increase. Hence, the correct option is (d).
