Using the Blasius shear-stress relation (12-68) and the power-law velocity profile, determine the boundary-layer thickness on a flat plate as a function of the Reynolds number and the exponent n

A 30 m length, 2 MHz-operating lossless transmission line with characteristic impedance Z0 = 50 ohm. A load terminates a transmission line with a 50 impedance.

What is transmission line?

For a transmission line, the typical impedance is always 75 or 50 ohm. Since the transmission line is a distributed parameter component, the two portions vary continually. The term "50 ohm transmission line" designates a line with a characteristic impedance of 50 ohms. The impedance that corresponds to the minimal loss, maximum power, and maximum voltage is 50 Ohms, which is the least undesirable . Signal reflection is avoided whenever a transmission line with a finite length is terminated by a load impedance that is equal to the characteristic impedance.

Answer: The specific heat of the metal can be calculated using the formula Q = mcΔT, where Q is the heat absorbed by the metal, m is the mass of the metal, c is the specific heat of the metal, and ΔT is the change in temperature. Since we know the heat absorbed by the metal (10,000 joules) and the mass of the metal (200 grams), we can solve for the specific heat by rearranging the equation to solve for c:

Q = mcΔT

c = Q / mΔT

c = (10,000 joules) / (200 grams * 80 degrees Celsius)

c = 0.625 joules/gram-degree Celsius

Therefore, the specific heat of the metal is 0.625 joules/gram-degree Celsius, which corresponds to answer choice (c).

For a bjt, the emitter injection efficiency is 0.996, the base transport factor  ratio  is 0.992, β =1 and α =0.5

The ratio of a transistor's collector and emitter currents, or alpha factor (), is always less than one (between 0.5 and 1). The ratio of its collector and base currents, known as the beta () or current gain ( = Ic/Ib), is always greater than 1. The factor is alternatively calculated using the formula = /(+1)

β = 0.996/ 0.992=1

α = β/(β+1) .=1/1+1=1/2=0.5

Hot working refers to the metal forming process when it is carried out above the recrystallization temperature. Typically, it is between 0.6Tm times the melting point of base metal.

When newly treated, polished, or broken, a material takes on a bright look and conducts electricity and heat reasonably well. Metals are typically ductile and malleable. These traits are the result of the metallic bond that connects the atoms or molecules of the metal. A metal can be a molecular compound like polymeric sulphur nitride, an alloy like stainless steel, a chemical element like iron, or any combination of these. In physics, any substance that can conduct electricity at absolute zero degrees is commonly referred to be a metal. Numerous compounds that are not normally thought of as metals can become metallic when subjected to extremely high pressures. For instance, the nonmetal iodine progressively changes into a metal when subjected to pressures between 40 and 170 thousand.

In the georelational model, the data scale of the values used to associate features with records in a relational database is "character" (Option E)

In the georelational model, the data scale of the values used to associate features with records in a relational database is character. The georelational model is a way of storing geographic data in a relational database, in which features (such as points, lines, and polygons) are associated with records in the database through character values. These character values may be alphanumeric codes or names that represent the features.

A georelational data model is a geographic data model that depicts geographic characteristics as a combination of spatial and attribute data that is interconnected. The basic data model utilized in coverages is the georelational model.

It varies from the georelational data model in two key ways. In a single system, the object-based data model holds both spatial and attribute data for spatial characteristics. The object-based data model associates a spatial characteristic (object) with a set of attributes and operations.

The upward force of the rope and the downward force of the weight of nails must be exactly equal as it meets the bag. If there were a net force present there instead of zero, the point would be moving either upward or downward. Therefore, the rope's upward force at that location is 136 N.

The bag is not accelerating up or down if it is still. You can infer from that fact alone that there is no net vertical force acting on it. The total of all upward forces acting on it is therefore exactly equal to the gravitational force acting downward, or the "weight" of the bag. If the bag is strung from a single rope, the rope's tension must match the bag's 136-N weight. And if it is supported by four ropes, the total tension of those four ropes is 136N. I am unable to comment on the rope's increased level of tension. If the rope itself has any mass, then points further up must hold both the weight of the rope segment below the point as well as the weight of the bag of nails .If the rope has no mass, then its entire length is under 136 N of strain.

The answer for the second loop is, Total reads or loads = 16 * 16 * 2 = 512

So, Blank_4  = 512

Reads or loads that miss in the cache are 256  because accessing x-coordinates is always missed and accessing y-coordinate is always hit

Blank_5 = 256

Resulting in a cache miss rate is 256/512 = 0.5

Blank_6 = 50%

If the cache is twice as big, it would be 128/512 =0.25

Blank_7 = 25% because a cache was as large for storing the entire grid.

The length of the uniform steel bar is; 1.077 m

A physical pendulum is defined as an extended object that, for small angular displacements, it can be modeled to move in simple harmonic motion about a pivot that does not go through the center of mass. The period of this motion is given by the formula;

T = 2π√(I/mgd)

where;

I is the moment of inertia of the object about an axis through the pivot.

d is the distance from the pivot to the center of mass of the object.

The period of the pendulum is given as t = 1.7 seconds

The moment of inertia of the same bar rotating about an axis through one end is gotten from the formula;

I = ¹/₃ML²

Where L is the length of the bar

Since the bar is uniform, the middle of mass is found in the middle and as such; d = L/2

Thus;

T = 2π√(2I/mgL)

Put  ¹/₃ML² for I into the period formula and we have;

L = 3gT²/8π²
