Answer:
It creates Stronger and resistant polymers
Explanation:
Cross-linking is important in applications such as tires, adhesives etc because it increases the molecular mass of polymers. These cross-linked applications are important as they are strong mechanically, have good heat resistance and are also resistant to attacks by solvents and also wear. As these applications would get to be thicker and have more viscosity.
The importance of Cross-linking in certain applications such as tire, adhesive, and circuit boards production is to provide a material of more rigid structure and definite form.
What is crosslinking?Crosslinking is the chemical process of forming a covalent connection between two or more molecules. Crosslinking reagents are compounds with more than one reactive ends that are capable of chemically connecting to certain functional groups called polymers.
Chemical crosslinking has long been employed to change the physical characteristics of polymeric materials. An example is seen in the vulcanization of rubber serving as a prime illustration.
Therefore, the importance of Crosslinking between polymer chains provide a material a more rigid structure and, ultimately, a better-defined form.

(5 points) Knowing that the ammeter must be connected in series with the circuit and the voltmeter must be connected in parallel, what does this tells you about the internal resistance of each device?
This tells us that the internal resistance of the ammeter is very low because we would not want to impede the flow of current when trying to measure current. The internal resistance of the voltmeter must be high because it is added in parallel with the circuit and if added in series, it would cause resistance and alter the voltage reading.

Do some research and find out whether the Pascaline calculator is a computer according to the Turing model.
No, it isn't. It can only perform basic mathematical calculations. A computer must be programmable in order to be Turing-complete.
What is Pascaline calculator?In 1642, Blaise Pascal invented the Pascal's calculator, a mechanical calculator. The laborious arithmetic calculations required by his father's work as the supervisor of taxes in Rouen inspired Pascal to create a calculator.
It must have some kind of programming language in which you can write instructions that can be followed automatically or by a human operator to perform any type of data processing.
Thus, it can be concluded that Pascaline calculator is not actually a computer according to the Turing model.

Air in a large tank at 300C and 400kPa, flows through a converging diverging nozzle with throat diameter 2cm. It exits smoothly at a Mach number 2.8. According to one-dimensional isentropic theory, what is
(a) exit diameter and
(b) mass flow?
Answer:
The answer is "[tex]3.74 \ cm\ \ and \ \ 0.186 \frac{kg}{s}[/tex]"
Explanation:
Given data:
Initial temperature of tank [tex]T_1 = 300^{\circ}\ C= 573 K[/tex]
Initial pressure of tank [tex]P_1= 400 \ kPa[/tex]
Diameter of throat [tex]d* = 2 \ cm[/tex]
Mach number at exit [tex]M = 2.8[/tex]
In point a:
calculating the throat area:
[tex]A*=\frac{\pi}{4} \times d^2[/tex]
[tex]=\frac{\pi}{4} \times 2^2\\\\=\frac{\pi}{4} \times 4\\\\=3.14 \ cm^2[/tex]
Since, the Mach number at throat is approximately half the Mach number at exit.
Calculate the Mach number at throat.
[tex]M*=\frac{M}{2}\\\\=\frac{2.8}{2}\\\\=1.4[/tex]
Calculate the exit area using isentropic flow equation.
[tex]\frac{A}{A*}= (\frac{\gamma -1}{2})^{\frac{\gamma +1}{2(\gamma -1)}} (\frac{1+\frac{\gamma -1}{2} M*^2}{M*})^{\frac{\gamma +1}{2(\gamma -1)}}[/tex]
Here: [tex]\gamma[/tex] is the specific heat ratio. Substitute the values in above equation.
[tex]\frac{A}{3.14}= (\frac{1.4-1}{2})^{-\frac{1.4+1}{2(1.4 -1)}} (\frac{1+\frac{1.4-1}{2} (1.4)^2}{1.4})^{\frac{1.4+1}{2(1.4-1)}} \\\\A=\frac{\pi}{4}d^2 \\\\10.99=\frac{\pi}{4}d^2 \\\\d = 3.74 \ cm[/tex]
exit diameter is 3.74 cm
In point b:
Calculate the temperature at throat.
[tex]\frac{T*}{T}=(1+\frac{\Gamma-1}{2} M*^2)^{-1}\\\\\frac{T*}{573}=(1+\frac{1.4-1}{2} (1.4)^2)^{-1}\\\\T*=411.41 \ K[/tex]
Calculate the velocity at exit.
[tex]V*=M*\sqrt{ \gamma R T*}[/tex]
Here: R is the gas constant.
[tex]V*=1.4 \times \sqrt{1.4 \times 287 \times 411.41}\\\\=569.21 \ \frac{m}{s}[/tex]
Calculate the density of air at inlet
[tex]\rho_1 =\frac{P_1}{RT_1}\\\\=\frac{400}{ 0.287 \times 573}\\\\=2.43\ \frac{kg}{m^3}[/tex]
Calculate the density of air at throat using isentropic flow equation.
[tex]\frac{\rho}{\rho_1}=(1+\frac{\Gamma -1}{2} M*^2)^{-\frac{1}{\Gamma -1}} \\\\\frac{\rho *}{2.43}=(1+\frac{1.4-1}{2} (1.4)*^2)^{-\frac{1}{1.4-1}} \\\\\rho*= 1.045 \ \frac{kg}{m^3}[/tex]
Calculate the mass flow rate.
[tex]m= \rho* \times A* \times V*\\\\= 1.045 \times 3.14 times 10^{-4} \times 569.21\\\\= 0.186 \frac{kg}{s}[/tex]

g Clay sized particles in a river are likely to be transported as _______________________, whereas gravel sized particles are likely to be transported as _____________________. Group of answer choices suspended load; dissolved load suspended load; bed load dissolved load; suspended load dissolved load; bed load
Answer:
suspended load; bed load
Explanation:
Suspended load is those particles in a river that are transported and float between and around the middle and top of the river, they often change the color of the river through their suspension such as clay.
Bed load is those particles in a river that are transported at the river bed or floor. This is as a result of their weight. Examples are relatively big stones.
Hence, in this case, Clay sized particles in a river are likely to be transported as SUSPENDED LOAD whereas gravel-sized particles are likely to be transported as BED LOAD

You are working on a residential heat pump. The heat pump is connected to a
240-V, 60-Hz power line. The compressor has a current draw of 34 amperes when operating. The compressor has a power factor of 70%. The backup strip heat is
rated at 10 kW. You need to know the amount of total current draw that will occur if
the strip heat comes on while the compressor is operating.
The amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.
How to find the total currentWe have the following details
Pe = 10 Kw
compressor current = 34A
Power factor = 70%
The voltage applied = 240 V
frequency f = 60 Hz
P = ER² / R
= 240² / 10 x 10
= 57600 / 10000
= 5.76Ω
We have El = Lr = Et
El = Lr = 240
The true power P
10 x 10³ / 240
= 41.667 A
The total current is solved by
√41.667² + 34³
= √1736.138 + 1156
= √2892.138
= 53.778 A
Hence the amount of total current draw that will occur if the strip heat comes on while the compressor is operating is 53.778 A.

What is the safe psi pressure for acetylene
Answer:
15psig
Explanation:
Statement 1: All balls hit the ground at the same time. Statement 2: All balls hit the ground with the same force. Statement 3: The bowling ball hit the ground first and the tennis golf ball hit the ground last. Statement 4: It is not possible to tell how much force each ball hit the ground with. Which statements must be TRUE regarding the rate of force of each falling object. Neglect air resistance.
Answer:
Statement 1: All balls hit the ground at the same time
Explanation:
When there is no resistance of air, the acceleration due to gravity experienced by all the bodies are same. So for falling bodies, neglecting the air resistance, the falling object will be weightless and therefore all the objects will hit the ground at the same time when there is nor air resistance and the objects are considered to be falling in vacuum.

Answer:
[tex]2.9\times 10^{-6}[/tex]
Explanation:
[tex]Q_s[/tex] = Energy for defect formation = 1.86 eV
T = Temperature = [tex]573^{\circ}\text{C}=573+273.15=846.15\ \text{K}[/tex]
k = Boltzmann constant = [tex]8.62\times 10^{-5}\ \text{eV/K}[/tex]
The fraction of lattice sites that are Schottky defects is given by

A parallel-plate capacitor is disconnected from a battery, and the plates are pulled a small distance further apart. Do the following quantities increase, decrease, or stay the same?.
Answer: capacitance decreases as distance increases
Explanation: when the plates on the capacitor are being pulled what happens is it will decrease in capacitance so the charge will decrease in the capacitor and because the battery is pulled away and if the plate is fully charged the capacitance as the distance increases between the plates the capacitance drops and heres something else i found on it and the capacitance
Capacitance C∝d1 when plates of a capacitor are moved farther, the capacitance decreases. After disconnecting the battery, the charge on capacitor remains constant, therefore the energy stored by capacitor U (=2Cq), increases
