9.24 a design error has resulted in a gross mismatch in the circuit of fig. p9.24. specifically, q2 has twice the w/l ratio of q1. if vid is a small sine-wave signal, find:
Drain current for Q1, \(i_{D1}\) = I / 3
Drain current for Q2, \(i_{D2}\) = 2 I / 3
Drain current for Q1 is,
\(i_{D1}\) = 1 / 2 \(k'_{n}\) ( W / L ) ( \(v_{GS1}\) - \(V_{t}\) )²
Drain current for Q2 is,
\(i_{D2}\) = 1 / 2 \(k'_{n}\) ( 2 W / L ) ( \(v_{GS2}\) - \(V_{t}\) )²
From the circuit, for both Q1 and Q2 transistors,
Gate voltage = Source voltage = Threshold voltage
So,
\(v_{GS1}\) - \(V_{t}\) = \(v_{GS2}\) - \(V_{t}\)
\(i_{D2}\) = 1 / 2 \(k'_{n}\) ( 2 W / L ) ( \(v_{GS2}\) - \(V_{t}\) )²
( \(v_{GS2}\) - \(V_{t}\) )² =\(i_{D2}\) / [ 1 / 2 \(k'_{n}\) ( 2 W / L ) ]
\(i_{D1}\) = 1 / 2 \(k'_{n}\) ( W / L ) ( \(v_{GS1}\) - \(V_{t}\) )²
\(i_{D1}\) = 1 / 2 \(k'_{n}\) ( W / L ) ( \(v_{GS2}\) - \(V_{t}\) )²
\(i_{D1}\) = 1 / 2 \(k'_{n}\) ( W / L ) \(i_{D2}\) / [ 1 / 2 \(k'_{n}\) ( 2 W / L ) ]
\(i_{D1}\) = \(i_{D2}\) / 2
\(i_{D1}\) / \(i_{D2}\) = 1 / 2
In the circuit, constant bias current imposes the constraint.
\(i_{D1}\) + \(i_{D2}\) = I
\(i_{D2}\) = I - \(i_{D1}\)
\(i_{D1}\) / \(i_{D2}\) = 1 / 2
\(i_{D1}\) / ( I - \(i_{D1}\) ) = 1 / 2
\(i_{D1}\) = I / 2 - \(i_{D1}\) / 2
\(i_{D1}\) + \(i_{D1}\) / 2 = I / 2
3 \(i_{D1}\) / 2 = I / 2
\(i_{D1}\) = I / 3
\(i_{D1}\) / \(i_{D2}\) = 1 / 2
I / 3 = \(i_{D2}\) / 2
\(i_{D2}\) = 2 I / 3
Therefore,
Drain current for Q1, \(i_{D1}\) = I / 3
Drain current for Q2, \(i_{D2}\) = 2 I / 3

Given :
An ant is crawling along a yardstick that is pointed with the 0-inch mark to the east and the 36-inch mark to the west.
It starts at the 14-inch mark, crawls to the 20-inch mark, then moves to the 16-inch mark.
To Find :
The total distance the ant traveled.
Solution :
Total distance travelled by ant = (distance between 14 and 20 inch mark) +
(distance between 20 and 16 inch mark)
Total distance = (20-14 ) + ( 20-16) = 6 + 4 = 10 inch.
Therefore, total distance the ant traveled is 10 inch.
Hence, this is the required solution.
What distance is required for a train to stop when traveling 50 miles per hour? half mile one and a half miles four miles
One and a half miles of distance is required for a train to stop when traveling 50 miles per hour.
Rate of change in position, or speed, is equal to distance traveled divided by time. To solve for time, divide the distance traveled by the rate.
Rearranging the formula,
Speed = distance / time.
Distance = speed × time.
Time = distance / speed.
Hence,
Distance = Speed × Time
⇒ Distance = 50 × 60 / 2000
⇒ Distance = 1.5 miles
⇒ Thus, the distance which is required to stop a train is 1.5 miles, which is, One and a half miles.

a solar pv array has an output voltage of 220v and the rated current of 6 a at best conditions (knee of the i-v curve at most solar radiation energy). the output needs to be boosted to 400 v (dc) by a boost converter. assuming the switching frequency fs
To boost the output voltage of the solar PV array to 400V using a boost converter, the output current of the converter needs to be approximately 3.3A.
A boost converter is used to increase the output voltage of a solar PV array. In this case, the solar PV array has an output voltage of 220V and a rated current of 6A at best conditions. The goal is to boost the output voltage to 400V (DC) using the boost converter.
To achieve this, we can use the formula for power, which is P = V x I. Since the power remains constant, we can equate the input power (220V x 6A) to the output power (400V x I), where I is the output current.
From this equation, we can solve for I:
220V x 6A = 400V x I
1320W = 400V x I
I = 1320W / 400V
I = 3.3A
Therefore, the output current of the boost converter needs to be approximately 3.3A in order to achieve an output voltage of 400V.
In conclusion, to boost the output voltage of the solar PV array to 400V using a boost converter, the output current of the converter needs to be approximately 3.3A.

How to integrate 1/ 1 + x2
The integral of 1/(1 + x²) is (1/2)ln|1 + x²| + C where C is the constant of integration.
Integration is a mathematical process of finding the antiderivative of a function. To integrate the given expression 1/(1 + x²), we will use the substitution method.
Let u = 1 + x², du/dx = 2x dx, then dx = du/2x and the integral becomes:
∫1/(1 + x²) dx = ∫1/u * (1/2x) du= (1/2)∫1/u du
The antiderivative of 1/u is ln|u| + C, where C is the constant of integration.
Therefore, the final solution of the integral is (1/2)ln|1 + x²| + C.
Let us work through the steps:
Step 1:Let u = 1 + x² and then differentiate both sides with respect to x to obtain du/dx. du/dx = 2x
Substitute 2x dx = du into the integral ∫1/(1 + x²) dx to get the integral in terms of u:∫1/u * (1/2x) du = (1/2) ∫1/u du
Step 2:Calculate the antiderivative of 1/u, which is ln|u|. Thus, the final solution is (1/2)ln|1 + x²| + C, where C is the constant of integration. The constant C will vary depending on the initial conditions of the problem.

1 ptThe movement of crustal plates results from circulating currents in material beneath the crust of Earth. Which BEST describes the material which moves the crustal plates?hot watermolten rockliquid metalsolid iron
The movement of crustal plates results from circulating currents in the mantle material beneath the crust of Earth. The mantle material is made up of molten rock and solid iron.
Crustal plates are large areas of the Earth's crust that float on the underlying molten mantle. The plates are in constant motion and move a few centimeters each year. Earth's crust is made up of about a dozen of these plates.
The heat causes the molten rock and solid iron to flow, producing convection currents. The movement of the mantle material drives the movement of the crustal plates, causing them to shift and collide with each other.
There are two types of crustal plates: oceanic plates and continental plates. Oceanic plates are thinner and denser than continental plates, and they are found beneath the oceans.
The movement of crustal plates has several effects on the Earth's surface. These include the formation of mountains, the creation of new land, the formation of valleys, and the creation of earthquakes and volcanic activity. When two plates collide, they can form a mountain range.

consider a steam engine whose working fluid always stays within the quality range of 0.0 to 1.0. the system operates between the pressure limits of 6.8 mpa and 1.21 mpa. if heat is supplied to the engine at a rate of 250 kw, what is the maximum power that could be produced by the engine?
The maximum power that could be produced by the steam engine is approximately 88.2 kW. The maximum power that could be produced by the steam engine can be calculated using the thermodynamic equation for the efficiency of a Carnot cycle, which is given by:
η = (T₁ - T₂) / T₁
where η is the efficiency, T₁ is the temperature of the heat source, and T₂ is the temperature of the heat sink. In this case, the heat source temperature is unknown, but we can find it using the saturation temperature at the pressure of 6.8 MPa, which is approximately 364°C. Similarly, the temperature at the heat sink pressure of 1.21 MPa is approximately 191°C.
Using the efficiency equation and the given heat input rate of 250 kW, we can calculate the maximum power output of the steam engine as:
P max = η * Qin
where P max is the maximum power output and Qin is the heat input rate. Plugging in the values, we get:
P max = η * 250 kW = (364 - 191) / 364 * 250 kW ≈ 88.2 kW
Therefore, the maximum power that could be produced by the steam engine is approximately 88.2 kW.

Explanation:
Ball A has a mass of 50 kg. Ball B has a mass of 75 kg. Both move at the same velocity. Which has a greater momentum?
Answer:
Ball B
Explanation:
I say this because its the heavier one?
The momentum of a body increases with increase in mass. Hence, among the two balls, the ball with the greater mass that is ball B has the greater momentum.
What is momentum ?Momentum is the ability of a moving object to bring the force effective to make maximum displacement. It is the product of mass and velocity.
P = mv
Thus, as the velocity and mass increases, the momentum increases. The force applied on a body with greater mass makes greater acceleration and greater momentum.
Therefore, at constant velocity, the object with the greater mass will have the greater momentum. Then, the ball with 75 kg mass is having the greater momentum.

Hence, the acceleration will be 16 m/s²
According to Newton's second law of motion, acceleration of an object is directly proportional to the net force acting on it keeping the mass of the object constant.
Mathematically,
F ∝ a
It means that when there is no net force acting on the body, there is no acceleration. A force is a push or a pull, and the net force ΣF is the total force, or sum of the forces exerted on an object in all directions. When the net force is increased or decreased by a factor of X, then acceleration also increased or decreased by a factor of X respectively according to Newton's 2nd law of motion.

a. If it took 3,600 seconds to do this, how much work was done by the tugboat?
b. If the tugboat pulled the cargo ship with a force of 306,000 N, how far was it pulled?
Answer:
the work done by the tugboat was 550,800,000 J and the distance that the cargo ship was pulled was 1,800 m
Explanation:
To solve this problem, we need to use the following formulas:
Work done = Power x Time
Power = Force x Velocity
Work done = Force x Distance
a. To find the work done by the tugboat, we can use the first formula and plug in the given values:
Work done = Power x Time Work done = 153,000 W x 3,600 s Work done = 550,800,000 J
b. To find the distance that the cargo ship was pulled, we can use the third formula and rearrange it to solve for distance:
Work done = Force x Distance Distance = Work done / Force Distance = 550,800,000 J / 306,000 N Distance = 1,800 m
