The answer is "82.2 torr"

Explanation:

moles of Xe:

[tex]= \frac{0.06}{131.293} \\\\ =0.00045699313 \ \mol[/tex]

moles of [tex]F_2[/tex]:

[tex]= \frac{0.0274}{38} \\\\= 0.00072105263\ \ mol[/tex]

moles of produced [tex]XeF_2:[/tex]

[tex]= 0.00024[/tex]

moles of left [tex]Xe[/tex]:

[tex]= 0.00021[/tex]

Calculate the Pressure:

[tex]= \frac{(0.08206\times 0.00024 \times 293)}{(.1)} + \frac{(0.08206\times 0.00021 \times 293)}{(.1)} \\\\= 0.10819611 \ \ atm \\\\ = 0.10819611 \times 760 \\\\ = 82.2 \ \ torr[/tex]

Answer:

12 N

Explanation:

Use Newton's second law:

∑F = ma

F = (2.4 kg + 1.3 kg) (3.2 m/s²)

F = 11.84 N

Rounded to two significant figures, the force is 12 N.

Answer:

1 kw-hr = 1000 w * 3600 sec = 3.6E6 Joules

E = P t = 120 J/C * 8 C/sec * 3600 sec /hr * 15 hr =   5.18E7Joules

where E is energy used by microwave

5.18E7 / 3.6E6 * .11 = $1.58    cost to run for 15 hrs

If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.

A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.

One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.

In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.

A spinning top (also called easily a top) is a specific toy that does not utilize the gyroscope effect during its movement.

The gyroscope effect refers to the characteristic that allows an object to maintain a constant direction of axis rotation when it is rotating.

This effect (gyroscope effect) mainly depends on the velocity of the object and its direction.

The gyroscope effect is exploited by many applications such as in missiles or satellites when they are in orbit.

C. Mintu should have chosen a material with a lower specific heat.

Explanation:

Sorry I'm late

I took the test and got 100%

Mintu's error is from, Mintu should have chosen a material with a lower specific heat.

Option  C is correct

The amount of heat required to raise the temperature of one gram of a substance by one Celsius degree is known as specific heat.

In conclusion,since Mintu wants to increase the heat transfer between a metal iron and another piece, Mintu should have chosen a material with a lower specific heat.

Answer:

Experimental variablr

Explanation:

I just did it:)

Option C is correct. The image is located between F and the center of the lens, on the other side of the lens the upright than the actual object.

Virtual and imaginary image is the type of upright image. A virtual picture is generated when light rays appear to meet at a certain spot following reflection from a mirror.

The picture that appears right-side-up is called an erect image. Unlike a virtual image, it is created by the real junction of light beams.

The lens in the illustration is a concave lens. The light rays that fall from the item onto the lens diverge, making it a diverging lens.

The item is held between the focus and the lens's center. At the same side of the item, an image would form between the focus and the lens's center.

The picture would be simulated, shrunk, and centered. As a result, the correct answer is: "The picture is upright."

Hence option C is correct

Answer: 28.71 km

Explanation:

For the convex mirror (ocean):

Radius of curvature = 6.4*10^3 km

Focal length (f) = R/2 = 3.2*10^3 km

Object distance (u) = -3.84*10^5

Mirror formula: [tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{1}{u} + \frac{1}{v} = \frac{1}{f}[/tex]

[tex]\frac{-1}{3.84*10^5} + \frac{1}{v} = \frac{1}{3.2*10^3}[/tex]

v = 3173.55km

Magnification, [tex]m = \frac{-v}{u} = \frac{-3173.55}{-3.84*10^5} = \frac{h_{i} }{h_{o} }[/tex]

So, height of image/height of object = 3173.55/3.84*10^5

Diameter of image = 3173.55/3.84*10^5 * 3475

Diameter of image = 28.71 km

Therefore, the diameter of the image is 28.71 km

The displacement of the cyclist from point A to B is 39.3 m.

The displacement of the cyclist is equal to the change between the final position and initial position of the cyclist. This can also be described as the shortest distance between two positions.

From the given image, the displacement of the cyclist from point A to B can be determined by formula for calculating length of arc,

D = (θ/360) x 2πr

D = (90/360) x 2π x 25

D = 39.3 m

Thus, the displacement of the cyclist from point A to B is 39.3 m.
