What are some advantages of making electronic components like transistors increasingly smaller?
Answer:
Dr. Engelbart, who would later help develop the computer mouse and other personal computing technologies, theorized that as electronic circuits were made smaller, their components would get faster, require less power and become cheaper to produce — all at an accelerating pace
x − 3y − 8z = −10 2x + 5y + 6z = 13 3x + 2y − 2z = 3
Answer:
consistent; dependent; infinite
Explanation:
Subtract the first equation from the third equation.
3x + 2y − 2z = 3
− (x − 3y − 8z = −10)
2x + 5y + 6z = 13 Subtract.
Because the resulting equation is identical to the second equation, the system is consistent and dependent with infinitely many solutions.

Adhered ceramic veneer has a thickness of less than _______.
O 1/4 inch
O 1/2 inch
O 3/4 inch
O 1 inch
Answer:
the answer is D
Explanation:
i took the test
Adhered ceramic veneer has a thickness of less than 1 inch. Thus, option D is correct.
What will be the calculation for thickness?the width of the wall is 21 3/8 = 171/8
the width of a tile is 4 1/2 = 9/2
so the number of tiles is
(171/8) / (9/2) = 171x2 / (9 x8) = 4.75
so the no of tiles needed is 5.

4. On wet roads, the chance of hydroplaning increases with the increase of speed.
True
False
Answer:
The answer to the question is True
On wet roads, the chance of hydroplaning increases with the increase of speed. Thus, the given statement is true.
During rainy weather, roads may become slippery and difficult to drive on. Slippery roads may also arise as a result of snow or ice. The fact that the road surface has less traction than normal is what makes it slippery. On slippery roads, it is recommended that drivers slow down to reduce the risk of skidding, sliding, or losing control of their cars, especially when taking turns.
Drivers should also increase their following distance and avoid abrupt braking or accelerating. Drivers should not drive faster than 25 mph on slippery roads, and they should not increase their speed to avoid hydroplaning. Instead, drivers should slow down.

Question 3
Sometimes when people first hear about the Traveling Salesman problem, they think: "Oh, that's not hard. Start with a city on the map; move to the nearest unvisited city; and then on each subsequent step, move to the nearest still-unvisited city, until you're done." This strategy is called a "greedy strategy": it always goes to the nearest allowed step.
Now consider four cities, all placed along the number line. City A is at point 0, City B at point 2, City C at point 3, and City D at point 10:
A B C D
00-01-02-03-04-05-06-07-08-09-10
Now, start a traveling salesman tour at City B, and use the greedy algorithm to choose your tour of the four cities, beginning and ending at B. How long is the greedy algorithm’s tour?
Answer:
22
Explanation:
The tour length will be the sum of the lengths of its segments. Here, we will figure the length using the greedy algorithm.
__
Starting at B=2, the nearest unvisited city is C=3, a distance of 1.
From C, the nearest unvisited city is A=0, a distance of 3.
From A, the nearest unvisited city is D=10, a distance of 10.
The return trip from D to B is a distance of 8.
The total length of the tour is ...
1 + 3 + 10 + 8 = 22

Why is Math mandatory in engineering?
Answer:
because Engineering focuses largely on designing and developing solutions to problems, and engineers often need to perform equations and calculations as part of the process of developing, building and testing the solutions they design.Explanation:
A ball is dropped from rest from the top of a cliff that is 30 m high. From ground
level, a second ball is thrown straight upward at the same instant that the first ball is dropped.
The initial speed of the second ball eventually hits the ground. In the absence of air resistance,
the motions of the balls are just the reverse of each other. Determine how far below the top of
the cliff the balls cross paths.v
The distance below the top of the cliff that the two balls cross paths is 7.53 meters.
Given the following data:
Initial velocity = 0 m/s (since the ball is dropped from rest).Height = 30 meters.Scientific data:
Acceleration due to gravity (a) = 9.8 [tex]m/s^2[/tex].To determine how far (distance) below the top of the cliff that the two balls cross paths, we would apply the third equation of motion.
How to calculate the velocity.Mathematically, the third equation of motion is given by this formula:
[tex]V^2 = U^2 +2aS[/tex]
Where:
V is the final velocity.U is the initial velocity.a is the acceleration.S is the distance covered.Substituting the parameters into the formula, we have;
[tex]V^2 = 0^2 +2(9.8) \times 30\\\\V^2 = 588\\\\V=\sqrt{588}[/tex]
V = 24.25 m/s.
Note: The final velocity of the first ball becomes the initial velocity of the second ball.
The time at which the two balls meet is calculated as:
[tex]Time = \frac{S}{U} \\\\Time = \frac{30}{24.25}[/tex]
Time = 1.24 seconds.
The position of the ball when it is dropped from the cliff is calculated as:
[tex]y_1 = h-\frac{1}{2} at^2\\\\y_1 = 30-\frac{1}{2} \times 9.8 \times 1.24^2\\\\y_1 = 30-7.53\\\\y_1=22.47\;meters[/tex]
Lastly, the distance below the top of the cliff is calculated as:
[tex]Distance = 30-22.47[/tex]
Distance = 7.53 meters.

Calculate the charge stored in a 2 microFarads capacitor with a voltage of 50V applied on it
Answer:
Charge = 0.1 Coulmbs
Explanation:
Q=CV
Q being the charge in coulombs
C being the capacitance
V being the voltage
You will multiply the capacitance value by the voltage and that equals your charge in coulombs
(50V) * (2mF) = 0.1 Coulombs
Electric Charge itself is defined as a property of matter to experience a force when placed in a CHANGING magnetic field.
A 3 mm diameter and 5 m long electric wire is tightly wrapped with a 2 mm thick plastic cover whose thermal conductivity is k= 0.15 W/m°C. Electrical measurements indicates that a current of 10A and voltage drop of 8V along the wire. If the insulated wire is exposed to a medium at T∞= 30C with h= 12 W/m2°C, determine the temperature at the interface of the wire and the plastic cover in steady operation. Also, determine whether doubling the thickness of the plastic cover will increase or decrease this interface temperature.
Answer:
According to the problem the diameter of the wire , r1
The outer diameter after wrapping , r2 = 7mm
The thickness of the plastic cover , t
Length of the wire = I
The Thermal conductivity of cover = = k
Current pass through the wire = I
Due to current passing voltage dropped, is V
The temperature = T
Heat transfer coefficient = h
The rate at which the heat is generated in the wire,
q= VI = 8 * 10 =80 Watt
Now for calculating the resistance for each medium .
x1 = 1/hA2 = 1/2 x 2π x 0.0035 x 5 = 0.76 K/ W
x2 = ln r2/r1/2πkl = ln 0.0035/0.0015 /2π 0.15 x 5 = 0.179 K/W
Therefore the total resistance ,
R = x1+x2 = 0.76 +0.179 = 0.939 K/W
Now to calculate the temperature at the interface of the wire,
q= R(T - t)
=> 80 = 0.939(T -30- 273)
T = 378.12 K
Critical radius is r(critical)
r(critical) = K/h = 0.15/12 = 0.0125 m or 12.5 mm
