Pegs A and B are restricted to move in the elliptical slots due to the motion of the slotted link.
Part A
If the link moves with a constant speed of 10 m/s , determine the magnitude of the velocity of peg A when x = 1. 2 m.
Part B
Determine the magnitude of the acceleration of peg A when x = 1. 2 m
Answers
For Part A, the velocity of peg A when x = 1.2 m can be calculated using the equation v = s/t, where s is the distance traveled and t is the time taken. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 1.2/10 = 0.12 s.
Therefore, the velocity of peg A when x = 1.2 m is v = 10/0.12 = 83.33 m/s.
For Part B, the acceleration of peg A when x = 1.2 m can be calculated using the equation a = (v2 - v1)/t, where v2 and v1 are the velocities of the peg at the two different points and t is the time taken to travel between them. Since the link is moving at a constant speed of 10 m/s, the time taken to travel 1.2 m is 0.12 s.
Therefore, the acceleration of peg A when x = 1.2 m is a = (83.332 - 102)/0.12 = -833.33 m/s2.

Answer:
B) gate-source junction is reverse-biased
Explanation:
FET is described as an electric field that controls the specific current and is being applied to a "third electrode" which is generally known as "gate". However, only the electric field is responsible for controlling the "current flow" in a specific channel and then the particular device is being "voltage operated" that consists of high "input impedance".

Answers
Answer:
La temperatura Kelvin que corresponde a 0 ºB es 493.15 Kelvin.
Explanation:
Sabemos que el punto de congelación del agua es 273.15 Kelvin y, según el enunciado, -60 ºB. Asimismo, el punto de ebullición de esta sustancia es 373.15 Kelvin y, según el enunciado, -10 ºB. Asumiendo una relación lineal, podemos determinar la temperatura en escala Kelvin equivalente a 0 ºB mediante la siguiente extrapolación:
\(T = 373.15\,K+\left[\frac{373.15\,K-273.15\,K}{-10\,^{\circ}B-(-60\,^{\circ}B)}\right]\cdot [0\,^{\circ}B-(-60\,^{\circ}B)]\)

Answers
Answer:
A) Not possible, B) Posible, C) Possible, D) Not possible.
Explanation:
The maximum theoretical efficiency for any thermal engine is defined by Carnot's cycle, whose energy efficiency (\(\eta\)), no unit, is expressed below:
\(\eta = 1-\frac{T_{L}}{T_{H}}\) (1)
Where:
\(T_{L}\) - Cold reservoir temperature, in Kelvin.
\(T_{H}\) - Hot reservoir temperature, in Kelvin.
If we know that \(T_{L} = 250\,K\) and \(T_{H} = 750\,K\), then the maximum theoretical efficiency for the thermal engine is:
\(\eta = 1-\frac{T_{L}}{T_{H}}\)
\(\eta = 0.667\)
For real thermal engines, the following inequation is observed:
\(0 \le \eta_{r} \le \eta\) (2)
Where \(\eta_{r}\) is the efficiency of the real heat engine, no unit.
There are two possible criteria to determine if a given heat engine is real:
Efficiency
\(\eta_{r} = 1 - \frac{Q_{L}}{Q_{H}}\) (3)
Where:
\(Q_{L}\) - Heat rejected to the cold reservoir, in kilojoules.
\(Q_{H}\) - Heat received from the hot reservoir, in kilojoules.
Power output
\(W = Q_{H}-Q_{L}\) (4)
Where \(W\) is the power output, in kilojoules.
Now we proceed to verify each case:
A) \(Q_{H} = 900\,kJ\), \(Q_{L} = 600\,kJ\), \(W_{m} = 400\,kJ\)
\(\eta_{r} = 0.333\)
\(0 \le \eta_{r} \le \eta\)
\(W = 300\,kJ\)
\(W \ne W_{m}\)
This engine is not possible.
B) \(Q_{H} = 900\,kJ\), \(Q_{L} = 500\,kJ\), \(W_{m} = 400\,kJ\)
\(\eta_{r} = 0.444\)
\(0 \le \eta_{r} \le \eta\)
\(W = 400\,kJ\)
\(W = W_{m}\)
The engine is possible.
C) \(Q_{H} = 900\,kJ\), \(Q_{L} = 300\,kJ\), \(W_{m} = 600\,kJ\)
\(\eta_{r} = 0.667\)
\(0 \le \eta_{r} \le \eta\)
\(W = 600\,kJ\)
\(W = W_{m}\)
The engine is possible.
D) \(Q_{H} = 900\,kJ\), \(Q_{L} = 100\,kJ\), \(W_{m} = 800\,kJ\)
\(\eta_{r} = 0.889\)
\(\eta_{r} > \eta\)
\(W = 800\,kJ\)
\(W = W_{m}\)
The engine is possible.

Many voltmeters today provide readings as numerical displays and are digital. By moving a pointer that shows voltage on a scale, the instruments previously mentioned can also offer readings in analogue form, but digital voltmeters are typically more accurate than analog ones.
For instance, a typical analogue voltmeter is likely to use an electromechanical system where the voltage is measured by translating the current passing through wire turns.
The only voltmeter that measures voltage directly rather than through the impact of other factors is the electrostatic voltmeter, which uses electrostatic forces.

In the single-phase mode of operation, How do the amplitudes of the forward and backward rotating magnetic fields compare to the amplitude of the rotating magnetic field for normal two-phases operation? How much torque can be produced during single-phase operation compared with normal two-phase operation?
Answers
During single-phase operation, the amplitudes of the forward and backward rotating magnetic fields are lower compared to the amplitude of the rotating magnetic field in normal two-phase operation, and the torque produced is also lower.
What are the differences in amplitudes of rotating magnetic fields and torque production between single-phase and normal two-phase operation?During single-phase operation, the amplitude of the forward and backward rotating magnetic fields is lower compared to the amplitude of the rotating magnetic field in normal two-phase operation.
In a normal two-phase system, two separate windings with a phase shift of 90 degrees are used to create a rotating magnetic field.
The amplitudes of these two magnetic fields are equal, and their combination creates a strong rotating magnetic field.
In single-phase operation, only one winding is used, resulting in a single-phase magnetic field.
This single-phase magnetic field produces a rotating magnetic field, but its amplitude is reduced compared to the two-phase operation.
The absence of the second winding with a 90-degree phase shift limits the strength of the rotating magnetic field in the single-phase mode.
As for the torque production, single-phase operation generally results in lower torque compared to normal two-phase operation.
The absence of the second winding and the reduced amplitude of the rotating magnetic field in single-phase mode lead to a weaker magnetic interaction with the rotor, resulting in lower torque production.
Overall, single-phase operation is less efficient and generates lower torque compared to normal two-phase operation due to the reduced strength of the rotating magnetic field.
It is typically used in applications with lower power requirements or where a dedicated two-phase power supply is not available.

what type of circuits have loads on separate branches of a loop?
Answers
Circuits that have loads on separate branches of a loop are known as parallel circuits.
In parallel circuits, the current has multiple paths to follow, as opposed to series circuits where the current flows through components in a single path. In a parallel circuit, each load (such as a resistor or an appliance) is connected across its own separate branch, creating multiple branches that connect to a common point. This arrangement allows each load to operate independently, and the total current is divided among the branches based on their individual resistances. Parallel circuits are commonly used in household electrical wiring, where different appliances are connected to separate branches of the circuit.

Consider the permutation on {1,2,3,4,5,6,7,8} given in cycle
notation by (3 1 4)∘(7 6 1 8 4).
Where is the number 8 sent by this permutaton?
Answers
The number 8 is sent to the number 4 by this permutation.
In the given permutation, (3 1 4)∘(7 6 1 8 4), the composition of two cycles is performed. Let's break it down step by step:
1. The first cycle, (3 1 4), implies that 3 is sent to 1, 1 is sent to 4, and 4 is sent back to 3. Any other numbers not mentioned in this cycle remain unchanged.
2. The second cycle, (7 6 1 8 4), means that 7 is sent to 6, 6 is sent to 1, 1 is sent to 8, 8 is sent to 4, and 4 is sent back to 7. Again, any numbers not explicitly mentioned in this cycle remain unaffected.
To determine where the number 8 is sent, we need to follow the path of the permutation. Initially, 8 is sent to 4 in the second cycle. Then, according to the first cycle, 4 is sent back to 3. Therefore, the number 8 is ultimately sent to 3 by this permutation.
In summary, the number 8 is sent to 3 by the permutation (3 1 4)∘(7 6 1 8 4).
