Explanation:
(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.
If you want to revise a sketch or a feature when using a 3D CAD program, how do you make a correction without using the undo function
Answer:
See explanation
Explanation:
Truthfully, this answer can vary depending on the CAD program you are choosing to use. Generally, you go to your model tree (this has been on the left hand side of the screen in all of the CAD software I have used) and click the sketch or feature to edit. In some programs this is a left click and in others this is a right click. When the feature is correctly selected a menu should appear with the option to edit feature/sketch/definition/etc. Select this option and you should be able to edit what you wanted to.

Beginning with model year 2008, what type of communication protocol is required for diagnostics?
Beginning with model year 2008, Controller Area Network (CAN) is required for diagnostics.
What is diagnostics?Diagnostics are defined as the process of identifying an injury, ailment, or disease based on the symptoms and signs a person is exhibiting. In order to confirm or rule out illnesses and diseases, diagnostic tests are utilized. Before creating a treatment plan, your doctor needs particular information from a diagnostic test to make an accurate diagnosis.
The robust automotive bus standard known as a Controller Area Network (CAN) enables microcontrollers and other devices to interact with each other's applications without the need for a host computer. Devices and CAN busses are frequently found in industrial and automotive systems. Bosch created the Controller Area Network (CAN) bus, which saw its debut in manufacturing in 1991.
Thus, beginning with model year 2008, Controller Area Network (CAN) is required for diagnostics.

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

Calculate the fraction of lattice sites that are Schottky defects for cesium chloride at 573 oC (this temperature is below the melting temperature (645oC)). Assume an energy for defect formation of 1.86 eV.
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
[tex]\dfrac{N_s}{N}=e^{-\dfrac{Q_s}{2kt}}\\\Rightarrow \dfrac{N_s}{N}=e^{-\dfrac{1.86}{2\times 8.62\times 10^{-5}\times 846.15}}\\\Rightarrow \dfrac{N_s}{N}=2.9\times 10^{-6}[/tex]

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

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.

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]

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.
