A circular hoop sits in a stream of water, oriented perpendicular to the current. If the area of the hoop is doubled, the flux (volume of water per unit time) through it:___________
Answer:
The flux (volume of water per unit time) through the hoop will also double.
Explanation:
The flux = volume of water per unit time = flow rate of water through the hoop.
The Flow rate of water through the hoop is proportional to the area of the hoop, and the velocity of the water through the hoop.
This means that
Flow rate = AV
where A is the area of the hoop
V is the velocity of the water through the hoop
This flow rate = volume of water per unit time = Δv/Δt =Q
From all the above statements, we can say
Q = AV
From the equation, if we double the area, and the velocity of the stream of water through the hoop does not change, then, the volume of water per unit time will also double or we can say increases by a factor of 2

Cite three factors that influence the rate of drying, and explain how each affects the rate.
Temperature, Humidity, Evaporation these are the three factors that influence the rate of drying.
What elements affect the rate of drying?The moisture content and temperature of the grain, as well as the temperature, (relative) humidity, and velocity of the air in contact with the grain, all affect how quickly the grain dries. Usually speaking, moisture loss from food occurs more quickly the smaller the item is. Temperature. The more moisture the air can contain before getting saturated, the hotter it will be. In order to accelerate dehydration, drying systems are made to optimise temperature differences between the product and the drying air.
Heat is used to remove moisture during the drying process, which lowers the bulk and volume of the waste and lowers the transport and storage expenses.

Answer:
b. A view of a building seen from one side, a flat representation of one façade. This is the most common view used to describe the external appearance of a building.
Explanation:
An elevation is a three-dimensional, orthographic, architectural projection that reveals just a side of the building. It is represented with diagrams and shadows are used to create the effect of a three-dimensional image.
It reveals the position of the building from ground-depth and only the outer parts of the structure are illustrated. Elevations, building plans, and section drawings are always drawn together by the architects.
1. Consider three dielectric media with flat and parallel boundaries with refractive indices n1, n2, and n3. Show that for normal incidence the reflection coefficient between layers 1 and 2 is the same as that between layers 2 and 3 if n2 = √[n1n3]. What is the significance of this?
2. Consider a Si photodiode that is designed for operation at 900 nm. Given a choice of two possible antireflection coatings, SiO2 with a refractive index of 1.5 and TiO2 with a refractive index of 2.3 which would you use and what would be the thickness of the antireflection coating? The refractive index of Si is 3.5. Explain your decision.
Answer:
1) r12 = r23 ( This signifies that the waves interfere destructively )
2) SiO2 should be chosen , Thickness = 150 nm
Explanation:
1 ) Prove that; r12 = r23
i) Considering light travelling in medium 1 ( i.e. incident between layers 1 and 2 )
r₁₂ ( reflection coefficient ) = ( n₁ - n₂ ) / ( n₁ + n₂ )
= ( n₁ - √n₁ n₃ ) / ( n₁ + √n₁ n₃ )
= \(\frac{1- \sqrt{\frac{n3}{n1} } }{1+ \sqrt{\frac{n3}{n1} } }\)
ii) considering light travelling in medium 2 ( i.e. incident between layers 2 and 3 )
r₂₃ ( reflection coefficient ) = ( n₂ - n₃ ) / (n₂ + n₃ )
= ( √n₁ n₃ - n₃ ) / ( √n₁ n₃ + n₃ )
= \(\frac{1- \sqrt{\frac{n3}{n1} } }{1+ \sqrt{\frac{n3}{n1} } }\)
hence r12 = r23 ( This signifies that the waves interfere destructively )
2) Determine the antireflection coating to use and the thickness
Refractive index of SiO2 = 1.5
Refractive index of TiO2 = 2.3
an ideal refractive index for an antireflection coating ( n2 )
= √n₁ n₃ = √(1)(3.5) = 1.87
the refractive index closest to this value = 1.5 ( hence SiO2 will be chosen )
Thickness of SiO2 ( diameter )
= 900 / ( 4*n2 )
= 900 / ( 4 * 1.5 ) = 900 / 6 = 150 nm
Describe the similarities and differences between circuits with resistors combined in series and circuits with resistors combined in parallel
Answer:
from the below explanation... we can say that, in the series circuit, flowing current remains the same at each part of the circuit. While in parallel circuits, the voltage across two endpoints of the branches is the same as the supplied voltage.
Explanation:
1.
The components in a series circuit are arranged in a single path from one end of supply to another end. However, the multiple components in a parallel circuit are arranged in multiple paths wrt the two end terminals of the battery.
2.
In a series circuit, a common current flows through all the components of the circuit. While in a parallel circuit, a different amount of current flows through each parallel branch of the circuit.
3.
In the series circuit, different voltage exists across each component in the circuit. Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
4.
A fault in one of the components of the series circuit causes hindrance in the operation of a complete circuit. As against fault in a single component in a parallel network do not hinder the functioning of another part of the circuit.
5.
The detection of a fault in case of a series circuit is difficult, but it is quite easy in parallel circuits.
6.
The equivalent resistance in case of a series circuit is always more than the highest value of resistance in the series connection. While the equivalent resistance in the parallel circuit is always less than any of the individual resistances in parallel combination.
If a system of pulleys results in a force of 25% of the load, how far will the rope need to move to pull the load a distance of 10 feet?
Answer:
40 ft
Explanation:
Assuming no loss of energy in the system of pulleys, the work done is the same whether you move the load directly or through the pulleys.
W = Fd . . . . . . . . work is the product of force and distance
F(10 ft) = (0.25F)(d) . . . . . where d is the distance we want to find
d = 10F/(0.25F) = 40

technician a says that hard spots in a brake drum should be removed using a carbide-tip machining tool. technician b says that the drum should be replaced if hard spots are discovered. which technician is correct?
Technician B said that the drum should be replaced if hard spots are discovered and Technician B is only correct. And Technician A said that the hard spots in a brake drum should be removed using a carbide tip, Technician A is wrong.
What does a Drum brake do?
No matter whether the vehicle is moving forward or backwards, drum brakes produce uniform braking force. Drum brakes produce the same amount of braking force in both directions, which explains this. This kind is typically utilised for the passenger car's rear brakes.
what are carbide tips used for?
Woodworkers and artisans utilise carbide saw blades to make precise cuts for jobs that require little to no tear-out, such as creating cabinets or furniture. Table and mitre saws often use circular carbide tip blades.
The overheating of the brakes, which causes the metal to alter under heat stress, results in hard spots in the drum. Drum replacement is required when hard spots occur.

Step 1: Build the Board 1. Build an empty 8 x 8 board (call the Game Board array GB ) filled with zeros. (You must use the zeros command for this). 2. For your board we will assume that a value of 0 in that space means no boat there and a 1 means a boat is hidden there. 3. Use a FOR loop to control placing your Rowboats on the board. THINK ABOUT IT before you start writing code. It may take more than 6 attempts to place your 6 Rowboats because some spaces may be randomly picked more than once. So, you need a FOR loop with a very large number of iterations such as 10000 to ensure that you have a good chance to find 6 empty spaces for the Rowboats. 4. To place each Rowboat on the board: Each row number, m, and each column number, n, is a separate random number. You are to use the random number generator randi to randomly pick a space on the board like this: m = randi(8) and n = randi(8) o Check if the space (m,n) is empty using a logical test like: GB(m,n)==0. You also need to test if you still need to place more Rowboats on the board. o If both tests are true, then change the value of that space to 1 to show that you have placed a Rowboat there. That is, GB(m,n) = 1. You may also need to keep track of how many Rowboats you have put on the board. 5. After you have placed the 6 Rowboats on your board, use the instructions below to create an image of the board showing where the 6 Rowboats are positioned. • To show the board as an image, use these three commands: imagesc(GB) % GB is the name of your array axis square' % This makes your image a square shape and corrects for screen resolution title('My Row Boat Placement") % The title I want you to use for this problem. Put your name on the label for the x-axis. (Use the xlabel command as with plots.) o DO NOT put a label on the y-axis. Add another new command called "grid on" to draw thin lines showing your Row Boat placement. Add the following 2 lines of code to add tick marks and make your board image a bit prettier: xticks (1:1:8) yticks (1:1:8) You should see 6 Rowboats on your board. Next week we begin to talk more about images, but we wanted to introduce how to make an image, like the board, in preparation for that.
To build the board, the following steps are to be followed:Build an empty 8 x 8 board filled with zeros using zeros command. Consider 0 to represent no boat while 1 to represent the presence of a boat.
To place the rowboats, use a for loop to control and perform iterations for randomly placing 6 rowboats on the board. Using the random number generator randi to randomly pick a space on the board. To place each Rowboat on the board, you have to check whether the chosen space is empty or not using a logical test like GB(m,n) == 0. After checking the chosen space, if it's empty and needs to place more rowboats, then change the value of that space to 1, i.e., GB(m,n) = 1. Keep track of how many rowboats are placed on the board.

Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. Technician B says that latent heat is hidden heat that is required for a change of state of matter. Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B
Answer: C
Both A and B are correct
Explanation:
Latent heat is the hidden heat.
Latent heat is the heat energy required to change one state of matter to another state of matter without change in temperature. For example, solid state to liquid state, or liquid state to gaseous state.
Thermometer can not detect the latent heat. That is why it is called hidden heat.
If Technician A says that latent heat is hidden heat and cannot be measured on a thermometer. And Technician B says that latent heat is hidden heat that is required for a change of state of matter, then we can therefore conclude that both Technician A and Technician B are correct.
A particle in an experimental apparatus has a velocity given by v=k

1/2
s
−1
. If the particle has a velocity v
0
=2 mm/s at t=0, determine the particle position, velocity, and acceleration as functions of time. To check your work, evalutate the time t, the position s, and the acceleration a of the particle when the velocity reaches 10 mm/s.
Solving this equation will give us the value of t at which the velocity reaches 27 mm/s.
Given:
v = k√s
Integrating both sides with respect to s:
∫(1/v) dv = ∫(k√s) ds
ln|v| = (2/3)k(s^(3/2)) + C1
Taking the exponential of both sides:
|v| = e^[(2/3)k(s^(3/2)) + C1]
Since v is positive, we can remove the absolute value:
v = e^[(2/3)k(s^(3/2)) + C1]
Now, we need to find the constant C1. We know that v = v0 when t = 0:
v0 = e^[(2/3)k(s0^(3/2)) + C1]
Since v0 = 6 mm/s, we can rewrite the equation as:
6 = e^[(2/3)k(s0^(3/2)) + C1] ---- (1)
Next, to find the position as a function of time, we need to solve for s in terms of t. We can use the relationship v = ds/dt:
ds/dt = k√s
Rearranging the equation and integrating both sides with respect to t:
∫(1/√s) ds = ∫k dt
2√s = kt + C2
√s = (kt/2) + C2
Squaring both sides:
s = (k^2t^2/4) + C2kt + C2^2
Now, we need to find the constants C2. We know that s = s0 when t = 0:
s0 = (k^2(0)^2/4) + C2(0) + C2^2
Since s0 is the initial position, we can rewrite the equation as:
s0 = C2^2 ---- (2)
Now, let's evaluate the time t, position s, and acceleration a when the velocity reaches 27 mm/s. From equation (1), we have:
27 = e^[(2/3)k(s^(3/2)) + C1]
Substituting the expression for s from equation (2), we have:
27 = e^[(2/3)k(C2^(3/2)) + C1]
Solving this equation will give us the value of t at which the velocity reaches 27 mm/s.

Question 12 4 pts A memory RAM specified as 64M x 16 has how many address lines? O 15 O 25 0 26 O None of the choices listed O 16
A memory RAM specified as "64M x 16" has 22 address lines.
So, none of the choices listed (None of the choices listed) is the correct answer.
Explanation:
To determine the number of address lines in a memory RAM specified as "64M x 16," we need to consider the total number of memory cells and calculate the corresponding number of address lines.
The given specification "64M x 16" indicates that the memory has 64 megabits (M) of storage and each memory cell has a size of 16 bits.
To calculate the number of address lines, we can use the formula:
Number of Address Lines = log2(Total Number of Memory Cells)
Total Number of Memory Cells = Total Memory Size / Size of Each Memory Cell
In this case, the Total Memory Size is 64 megabits (64M), and the Size of Each Memory Cell is 16 bits.
Calculating the Total Number of Memory Cells:
Total Number of Memory Cells = 64M / 16 bits
Now, we can calculate the number of address lines using the formula mentioned earlier.
Number of Address Lines = log2(Total Number of Memory Cells)
Let's calculate it step by step:
Total Number of Memory Cells = 64M / 16 = 4M
Number of Address Lines = log2(4M)
Taking the logarithm base 2:
Number of Address Lines = log2(4) + log2(1M)
Since 2^2 = 4 and 2^20 = 1M:
Number of Address Lines = 2 + 20 = 22
Therefore, a memory RAM specified as "64M x 16" has 22 address lines.
So, none of the choices listed (None of the choices listed) is the correct answer.

A gas is contained in a vertical, frictionless piston– cylinder device. The piston has a mass of 3.2 kg and a crosssectional area of 35 cm2. A compressed spring above the piston exerts a force of 150 N on the piston. If the atmospheric pressure is 95 kPa. Determine the pressure inside the cylinder.
Answer:
Pressure = 51.8 x 10³ Pa = 51.8 KPa
Explanation:
First, we calculate the total force exerted on the piston:
Total Force = Force Exerted by Spring + Weight of Piston
Total Force = 150 N + (mass)(g)
Total Force = 150 N + (3.2 kg)(9.8 m/s²)
Total Force = 150 N + 31.36 N
Total Force = 181.36 N
Now, for cross-sectional area of piston:
Area = (35 cm²)(1 x 10⁻⁴ m²/1 cm²)
Area = 0.0035 m²
Now, for pressure inside the cylinder:
Pressure = Total Force/Area
Pressure = 181.36 N/0.0035 m²
Pressure = 51.8 x 10³ Pa = 51.8 KPa
