The bottom hole in the dam is blocked by a flat rectangular shield with a width of -6 m. The water depth in the upstream h1 = 23 m, the depth in the downstream h2 = 11.5 m, the height of the bottom hole t = 17.25 m, the angle of inclination a = 40 °. The sewing can rotate around the axis, which is projected to point A. Determine the force T required to raise the shield.

The ratio of the input voltage to the output voltage is known as the small signal voltage gain (Av): The tiny signal output current, io in the collector or drain, is equal to the input voltage V in (vbe for the BJT and vgs for the MOS) multiplied by the transconductance g m.

At each step of the VGS increase, record the drain current (ID). Divide the slight changes in the current ID by the small changes in VGS to obtain the transconductance (gm). A tiny signal is an AC signal that is overlaid on a bias signal (more precisely, a signal with zero average value) (or superimposed on a DC constant signal). This splitting of a signal into two halves enables the use of superposition to streamline subsequent analysis.This transconductance connects the output current to the transistor gain represented by the input voltage. Therefore, with a constant value of VDS, the formula for the slope of the transconductance curve is given as gm = ID/VGS.

Explanation:

False. Ion channels are usually closed and only open when stimulated by a signal such as a change in voltage or a chemical messenger.

Ion channels play a critical role in controlling plasma membrane permeability.

Ion channels are transmembrane proteins that open and close to control the entry and exit of ions across the plasma membrane. These channels open when they receive an external signal, such as a change in voltage or a chemical messenger.

Ion channels allow selective passage of ions across the plasma membrane. This means that some types of ions can pass through the membrane while others cannot. This selectivity allows the cell to control the exchange of ions with the external environment. Ion channels are also responsible for the conduction of ions across the plasma membrane, which allows cells to transmit signals across the plasma membrane.

The power that the engine will deliver at 3500 rpm is; 87.61 kJ/s

We are given;

Compression Ratio; V₁/V₂ = 22

Cut off ratio; V₃/V₂ = 1.8

Speed; N = 3500 rpm

The temperature after the compression is given by the formula;

T₂ = T₁(V₁/V₂)^(λ - 1)

Where;

T₁ is the temperature before compression

V₁ is the volume before compression

V₂ is the volume after compression

λ is the adiabatic constant of air = 1.4

We are given;

T₁  = 70°C = 70 + 273 = 343 K

Thus;

T₂ = T₁(22)^(1.4 - 1)

T₂ = 1181.03 K

The temperature after the constant pressure expansion in diesel cycle is given by the formula;

T₃/T₂ = V₃/V₂

Plugging in the relevant values;

T₃ = 1181.03 * 1.8

T₃ = 2125.854 K

The temperature T₄ after the isentropic expansion of air is given by the formula;

T₄ = T₃(V₃/V₄)^(λ - 1)

Plugging in the relevant values gives;

T₄ = T₃(1.8V₂/V₄)^(λ - 1)

where V₂/V₄ = V₂/V₁

Thus;

T₄ = T₃(1.8V₂/V₁)^(λ - 1)

T₄ = 2125.854(1.8/22)^(1.4 - 1)

T₄ = 781 K

The mass of air in the system is given by;

m = P₁V₁/RT₁

Where P₁ = 97 KPa and R is gas constant =  0.287kPa⋅m³/kg⋅K

Plugging other relevant values and solving gives;

m = 0.00236 kg

The ideal the specific heat of air at constant pressure cp using ideal gas properties table and by interpolation here is cp = 1.0076 kJ/kg.K

The  heat added to the cycle is given by the formula;

Q_in = mcp(T₃ - T₂)

Plugging the relevant values and solving gives;

Q_in = 2.246 kJ

The heat rejected by the cycle is given by the formula;

Q_out = mcv(T₄ - T₁)

cv is the specific heat at constant volume and from ideal gas properties table and by interpolation gives cv = 0.7205 kJ/kg.K

Thus;

Q_out = 0.00236 * 0.7205(781 - 343)

Q_out = 0.744 KJ

Thus, power that the engine will deliver at 3500 rpm is;

W' = N(Q_in - Q_out)

Where N = 3500 rpm = 3500/60 rps

Asynchronous Counter is a type of counter in which each flip-flop provides the clk input to the next flip-flop.

What is a Asynchronous Counter?

Asynchronous counters have had an output that really is independent of the clock signal. Because the flip flops in asynchronous counters are fed with different clock signals, output may be delayed.

The number of logic gates required to design asynchronous counters is very small. As a result, their design is straightforward. Asynchronous counters is also termed as the ripple counters.

The number of flip flops used in a ripple counter is determined by the number of counter states (ex: Mod 4, Mod 2 etc). The number of counter output states is referred to as the "Modulus" or "MOD" of the counter. A counter can have a maximum of 2n states, where n represents the number of flip flops used in the counter.

We are going to solve this question with the help of "Toll Bridge Puzzle" using strategies based on place value and properties of operations.

The image below depicts bridges connecting islands. You must pay a toll in coins to cross a bridge. How can you get to the island marked in red if you start on the island marked in blue with 100 coins?

Step-By-Step Explanation:

This task is designed to assess the addition of four numbers as specified in the standard while remaining in a problem-solving context.

This task is intended to be instructional; however, due to the random nature of when the correct route is discovered, it is not suitable for assessment.

This puzzle works well as a physical re-enactment, with paper plates representing the islands and strings with papers attached representing the tolls.

The single digit numbers will often lead students to believe that the route must pass that way. They may also miss the "crossover" by using the central island, finding the 23 + 25 + 29 + 24 route but not the 32 + 15 + 40 + 38 route or the 32 + 15 + 29 + 24 route.

Technically, paths that run from right to left along some bridges (for example, 32 + 5 + 41 + 40 + 29 + 24) could also be considered. In this case, however, such paths can be ignored because students will find a cheap enough path by only investigating paths that run from left to right. One might be tempted to modify the problem by having the student start with 99 coins and ask if reaching the red island is possible. Such a change, however, would be inappropriate because a mathematically valid solution would require the student to consider all paths, including those that cross some bridges from right to left.

Solution:

32 + 15 + 29 + 24 = 100

Other possible routes:

23 + 51 + 3 + 24 = 101

23 + 25 + 29 + 24 = 101

23 + 25 + 40 + 38 = 126

32 + 15 + 40 + 38 = 116

The natural frequencies and mode shapes of the three-degree-of-freedom system with one mass corresponding to the right wing, one mass for the left wing, and one mass for the fuselage can be calculated by solving the eigenvalue equation for the system. The mode shapes are the eigenvectors of the system and represent the relative displacement of the three masses for each mode. The mode shapes can be plotted to show the deflection of the wings and fuselage in response to the applied force or displacement.
To calculate the resulting vibration of the cabin, the impulse response of the system needs to be calculated with modal damping of 0.1 in each mode. This can be done by solving the differential equation describing the system and applying the impulse force at the ends of the left and right wings. The resulting vibration of the cabin can be found by solving the resulting equation.
To calculate the effect of the harmonic disturbance on the cabin and wing tips, the response of the system needs to be calculated with 10% modal damping in each mode. This can be done by solving the differential equation describing the system and applying the harmonic force at the cabin mass.
