Explanation:
what are the reasons why fine grained of alkali igneous rocks can not be used in cement
Fine grained of alkali igneous rocks cannot be used in cement because of the volume expansion caused by the Alkali-silica reaction, fine-grained igneous rocks cannot be used as aggregates in cement.
What does fine grained mean in an igneous rock?Extrusive igneous rocks have a fine-grained or aphanitic texture, with grains that are too small to see without a magnifying glass. The fine-grained texture suggests that the rapidly cooling lava did not have enough time to form large crystals. A petrographic microscope can be used to examine these tiny crystals.
The texture of an igneous rock (fine-grained vs coarse-grained) is determined by the rate at which the melt cools: slow cooling produces large crystals, while fast cooling produces small crystals.
The chemical reaction that occurs in both alkali cations and hydroxyl ions in the pore solution of hydrated cement paste and certain reactive silica phases present in concrete aggregates is known as the alkali-silica reaction (ASR).

technician a states that disc brake rotors can be of the hub-style. technician b states that disc brake rotors can be of the hubless-style. who is correct?
Both Technicians A and B are accurate when they say that disc brake rotors can be either hub-style or hubless-style.
With disc brakes, the brake pads attached to the brake callipers grip on the rotating braking rotors to stop or slow down the wheels. Friction is created by the brake pads pressing against the rotors, which turns kinetic energy into heat energy.
Although this thermal energy produces heat, it may be effectively dispersed since the primary components are exposed to the environment. This ability to dissipate heat lessens brake fade, a condition where heat affects how well a vehicle brakes. The resistance of disc brakes to water fade, which happens when water on the brakes considerably lowers braking force, is another benefit. The rotor spins rapidly as the car is moving, and this rotational motion discharges the water from the rotors themselves, resulting in stable braking force.

Although a weak entity set can be transformed into a strong entity set by adding appropriate primary-key attributes, but this strategy results in the redundant storage of the primary key. Since the primary key of the weak entity set can be deduced from its relationship with the strong entity set, if we add primary-key attributes to the weak entity set, then they will be present in both the relationship set and the entity set that need to be the same, resulting in the redundant storage of the primary key.

Using LRU Replacement Algorithm: 18 Page Faults.Using FIFO replacement Algorithm: 17 page FaultsUsing Optimal Replacement Algorithm: 13 Page Faults.What is demand Paging?
Demand paging is a way of managing virtual memory in computer operating systems. In a demand paging system, the operating system transfers a disk page into physical memory only if it is attempted to be accessed and the page is not already in memory.
The LRU page replacement method creates a new page by replacing the least recently used page in memory. The LRU page replacement technique is based on the idea that the least recently used page in memory will not be utilized for a long period.
The most basic page replacement technique is the FIFO Replacement Algorithm. In this technique, the operating system maintains a list of all pages in memory in a queue, with the oldest page at the top.
The best page replacement algorithm is optimal page replacement since it produces the fewest number of page defects. The pages that will not be utilized for the greatest period of time in the future are replaced by this algorithm.

This illustration demonstrates how to create parametric equalizer filters. Digital filters known as parametric equalisers are used in audio to modify the frequency content of a sound input. By permitting adjustments to the gain, centre frequency, and bandwidth of each filter, parametric equalisers offer capabilities beyond those of graphic equalisers. Graphic equalisers, on the other hand, only let you change the gain of the each filter. Typically, second-order IIR filters are used to create parametric equalisers. These filters have the issue of having relatively wide ripple or transition areas due to their low order, and when multiple of them are combined in a cascade, they may overlap.

What is vertical displacement?
Vertical displacement in tectonics refers to the movement of land inside a vertical direction, which causes uplift and subsidence. Rock layer displacement can reveal information about how and why the lithosphere of Earth evolves over the course of geologic time. Vertical displacement can be caused by a variety of processes, including isostatic adjustments and tectonic activity. When crust is reorganised as a result of a seismic event, tectonic activity causes vertical displacement. Vertical displacement as a result of sinking from an increased load and isostatic rebound from a removed load is the outcome of isostatic corrections. At the margins of convergent and divergent plate boundaries, tectonic activity results in vertical displacement. As the magma begins to rise to protrude weaker lithospheric crust, the movement of the magma in the asthenosphere can cause divergent plate boundaries.

calculate the percent yield of the product from bromination of cis-stilbene and the percent yield of the product from bromination of trans-stilbene.
Bromine and chlorine easily react with alkenes in addition reactions. This experiment involves brominating trans-stilbene with a 10% bromine dichloromethane solution. As a result, an addition reaction occurs, and 1,2-dibromo-1,2-diphenylethane is formed.
Step-by-step explanation:
stilbene + Br2 ----> PRODUCT(dibromostilbine)
No of moles of stilbene = 0.55/180.25 = 0.00305 mole
limiting reagent = stilbene
so that,
No of moles of PRODUCT = 0.00305 mole
massof product produced = 0.00305*260.25 = 0.793 gram
Theoretical yield = 0.793 gram
dibromostilbine molarmass = 260.25 g/mol
practical yield = 0.68grams
percent yield = practical yield /Theoretical yield *100
= 0.68/0.793*100 = 85.75%
Trans-stilbene acts as a nucleophile, while bromine acts like an electrophile. As a result, the bromine reagent electrophilically adds to the nucleophilic double bond. The Br-Br bond becomes polarized, and the more positively charged Br atom is transferred to the alkene, resulting in the formation of a bromonium ion.
Bromine addition begins on one side of the double bond (either side is equally likely, but only one option is chosen) and is followed by bromide ion attack on bromonium ion (again, attack could occur by carbon because the ion is symmetric, but only one option drawn). As shown above, the end result is a trans dibromide.

which microphone preamplifier input impedance would be best for a microphone that has an output impedance of 100 ohms?
A microphone preamplifier with an input impedance of 1,000 ohms would be best for a microphone that has an output impedance of 100 ohms.
What is microphone preamplifier?
The electronic circuitry found inside a microphone or a different object or circuit to which the microphone is linked can both be referred to as microphone preamplifiers. The microphone preamplifier serves the same role in either scenario. A microphone preamplifier is a piece of sound engineering gear that gets a microphone signal ready for other gear to handle. Frequently, microphone signals are too weak to be adequately conveyed to equipment like mixing consoles and recording devices. Preamplifiers boost a microphone signal to line level by offering steady gain and reducing generated noise, which would otherwise cause the signal to be distorted. See Gain stage for more discussion on signal level. Informally, a microphone preamplifier is referred to as a mic preamp, micamp, preamp, mic pre, and pre.

What is integer?
The collection of the whole numbers or negative numbers is known as an integer in mathematics. Integers, like whole numbers, do not include the fractional portion. Integers can therefore be defined as numbers that can be positive, negative, or zero but not as fractions. On integers, we can carry out all arithmetic operations, including addition, subtraction, multiplication, and division. Integer examples include 1, 2, 5, 8, -9, -12, etc. "Z" stands for an integer. Let's now go over the definition of integers, their symbol, types, operations, laws, and properties, as well as how to display them on a number line with numerous worked-out examples.

Mark all the correct operation/s that first, rotate x with p. Then, rotate x with g
p - parent
g - grandparent
x - node
let p and g be respectively the parent and grand parent of x. p is the root. Make x the new root by rotating edge(x,p).The Zig_Zig case p is the left child of g and X is the right child of p,making g the new parent of x rotating edge(x,g).
What exactly is zig-zig rotation?Every node in zig rotation shifts one position to the right of where it currently is. When the item to be searched is either a root node or a left child of a root node, Zig rotation is used.Zig does not allow null or 0 as a value for normal pointers. Where T is the child type, they use the syntax *T. Dereferencing is accomplished using variable, and referencing is accomplished using &variable.A particular kind of binary search tree is the splay tree. The splay tree is not necessarily balanced, unlike other versions like the AVL tree, the red-black tree, or the scapegoat tree.To learn more about zig rotation refer to:

1) (5 pts) (abet: 2) given the dfa below, give a regular expression that describes the language that it recognizes.
2((0+1)(0+1)*2+2)* is a regular expression that describes the language that it recognizes.
What is a regular expression?
A regular expression is a string of characters that specifies a text search pattern. String-searching algorithms typically use such patterns for "find" or "find and replace" operations on strings, as well as input validation. In theoretical computer science and formal language theory, regular expression techniques are developed.
SA=\epsilon (Eqaution 1)
SB=SB(0)+SB(1)+SB(2) + SA(0) + SA(1) (Eqaution 2)
SC=SA(2)+SD(2)+SC(2) (Eqaution 3)
SD=SC(0+1) + SD(0+1) (Eqaution 4)
Using arden's expression on equation 5 we can write it as:
SD=SC(0+1)(0+1)* (Equation 5)
We need to find SC to get the regular expression as it is the final state.
We substitute equations into one another to get the answers.
Substituting Equation 1 to equation 3 we get:
SC=\epsilon(2) + SD(2) + SC(2)
SC = (2+SD(2)) + SC(2)
Substituting Equation 5 into it we get:
SC=2+SC(0+1)(0+1)*2+SC(2)
SC=2+SC((0+1)(0+1)*2+2)
Using arden's therorem we can write it as:
SC=2((0+1)(0+1)*2+2)*
Hence 2((0+1)(0+1)*2+2)* is the regular expression that this DFA recongnizes.

the following data are obtained when open-circuit and short-circuit tests are performed on a single-phase, 50-kva, 2400/240-volt, 60-hz distribution transformer.
With relatively little power given to the transformer and winding currents of the same size as during operation, a short-circuit test is performed to determine the transformer impedance and losses.
What is open-circuit test on a single phase transformer?One approach used in electrical engineering to ascertain the no-load impedance of a transformer's excitation branch is the open-circuit test, also known as the no-load test. The open circuit, which is shown on the right side of the picture as the "hole" or incomplete component of the circuit, is a representation of the no load.Impedance series is neglected:E1 = N1/N2 = E2=N1/N2 V2 = (2400/240) 240<° = 2400<0°V
N2 / N1 I 2 = 240 / 2400(4.85) = 0.485A
GC = P2 / E1 ² = 173 / (2400)² = 3.003 × (10 )-5 S.
YC = (N2 / N1 I2)/E1 = 0.485 /2400 = 2.021 × (10-)4S
BM = √Y²C - G²C = √(2.021 ×( 10)-4)² - (3.003 × (10)-5 )² = 1.998 × (10 )-4 S
YC = GC - JBM = 3.003 × (10) -5 - j1.998 × (10)-4 S
