Air is contained in a piston-cylinder device at 9 bar and 927˚C, and occupies a
volume of 0.8 m3. The air undergoes an isothermal process until the pressure is
reduced to 4.5 bar. The piston is now fixed in place and not allowed to move while
a heat transfer process takes place until the air reaches 27˚C. Assume the air to be
a perfect gas. Take cp=1.005 kJ/kg∙K and cv=0.718 kJ/kg∙K.
(a) Calculate the final volume and final pressure of the air.
(6 marks)
(b) Determine the change in internal energy of the air, the work done
by the air and the total heat transferred.

Jar is a cylinder that has an R-radius and an H-height. The jar's volume is then calculated as V = R2H. The volume of honey in the jar is V honey = (1/2)R2(H/2) = (1/4)R2H if the honey fills the jar to half its height.

The volume of any cylinder with base radius "r" and height "h" equals base times height. A cylinder's volume is therefore equal to r2h cubic units.

F_buoyancy = (density of water) x (volume of water) x (acceleration due to gravity)

F_buoyancy = 1.0 x πR^2h x g

Since the jar is in equilibrium, the weight of the jar and honey must be equal to the buoyant force. Therefore, we can set the two equations equal to each other and solve for h:

3.5πR^2H x g = πR^2h x g

h = (3.5/1) x (H/2)

h = 1.75H

Therefore, the jar will sink into the water up to a height of 1.75 times its original height.

The tension in the rope and the spring balance reading are the same. 5N of tension is present on both sides. As a result, the spring balance reads 5N.

A simple and affordable way to determine mass is by using spring balances. The mass is suspended from the end of a spring, and the spring's deflection as a result of the mass's downward gravitational pull is measured in relation to a scale.

A spring balance calculates an object's weight by comparing the force of gravity to the force of an extended spring. The scale can be used to calculate weight and mass by recalibrating it. Some spring balances have gramme or kilogram marks and are used to determine an object's mass.

Answer:

C = So the largest animal that can fit under the new band is a 1 foot high opossum, which is smaller than the maximum height of 12,072,001 feet + 6 inches.

Explanation:

C = Pi * D = Pi * 25,000 miles

Converting this to feet, we get:

C = Pi * 25,000 miles * 5280 feet/mile = Pi * 132,000,000 feet

Adding 6 feet to the length of the band gives us:

C' = C + 6 feet = Pi * 132,000,000 feet + 6 feet

The new circumference is still the same distance from the center of the Earth as the original circumference, so we can use the formula for the circumference of a circle to find the radius of the circle that the band now forms:

C' = Pi * 2 * r

Solving for r, we get:

r = C' / (2 * Pi) = (Pi * 132,000,000 feet + 6 feet) / (2 * Pi)

Simplifying this expression, we get:

r = 66,000,003 feet / 2 = 33,000,001.5 feet

Now we can find the largest animal that can fit under the band by finding the maximum height of an animal that can fit under a circle with this radius.

Maximum height = r - radius = 33,000,001.5 feet - 20,928,000 feet = 12,072,001.5 feet

Converting this to feet and inches, we get:

Maximum height = 12,072,001.5 feet = 12,072,001 feet + 0.5 feet

= 12,072,001 feet + 6 inches

SOLVEM Steps:

S = State the problem

O = Organize the information

L = Label the variables

V = Verify the problem

E = Establish a strategy

M = Manipulate the variables

S: Suppose that the earth is a smooth sphere and you could wrap a 25,000 mile band snugly around it. If you lengthen the band by 6 feet, what would be the largest animal that can fit under the new band (assuming the band is equally above the earth's surface)?

O:

Original circumference = 25,000 miles

Additional length = 6 feet

L:

Let's label the radius of the earth as r, and the height of the animal as h.

V:

The problem seems to be well-formed and makes sense.

E:

We can use the original circumference of the earth to find its radius, and then calculate the new circumference by adding the extra 6 feet to the length of the band. Then we can solve for the maximum height of the animal that can fit under the new band.

M:

Convert the original circumference to feet:

C = 25,000 * 5280 feet/mile = 132,000,000 feet

Calculate the original radius of the earth:

C = 2πr

r = C / (2π) = 132,000,000 / (2 * 3.14159) = 21,008470.23 feet

Calculate the new circumference:

C_new = C + 6 feet = 132,000,006 feet

Calculate the new diameter and radius:

d_new = C_new / π = 42,016,942.38 feet

r_new = d_new / 2 = 21,008,471.19 feet

Calculate the maximum height of the animal:

h = r_new - r = 21,008,471.19 - 21,008470.23 feet=0.96 feet

If answer is 0.96 feet, the largest animal that can fit under the new band (assuming the band is equally above the earth's surface) would be a 1 foot high opossum (option c).

Explanation:

let the length be Lcm

5−325−L = 10−530−25

L = 23cm

Answer:

C. nylon

Explanation:

because it is definitely stronger than PLA And they are all not the same and acrylic isn’t strong than nylon

It should benotedtha for 100, repeat distance =ao=0.35167 nm

linear density=1/ao=2.84 points/nm

linear packing fraction =(2)(0.1243)(2.84) =0.707

For 110

repeat distance = 2*ao/2 = 0.2487 nm

linear density = 2 /( sqrt{2} * ao ) = 4.021 points/nm

linear packing fraction = (2)(0.1243)(4.02) =1.0

For 111,

repeat distance =(sqrt{3} * ao) = 0.6091 nm

linear density = 1 / (sqrt{3} * ao ) = 1.642 points/nm

linear packing fraction = (2)(0.1243)(1.642) =0.408

"Repeat distance" refers to the distance between repeated units in a crystal lattice. This can be measured along any of the lattice vectors that define the periodicity of the crystal. For example, in a simple cubic crystal, the repeat distance along any of the three lattice vectors would be equal to the length of that vector.

"Linear density" refers to the number of atoms or ions per unit length along a specific crystallographic direction. It is usually expressed in units of atoms/angstrom or ions/angstrom. To calculate the linear density, one would count the number of atoms or ions along a given direction and divide by the length of that direction.
