As the slit width increases, the diffraction pattern gets narrower and vice versa.
Relationship between width and diffraction patternThe increase in silt width leads to the narrowing of diffraction pattern of the light because the increase of width reduces the space for the passing of light wave.
So we can conclude that as the slit width increases, the diffraction pattern gets narrower and vice versa.

[tex]\rightarrow[/tex]A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
[tex]\rightarrow[/tex]Resistors reduce the current flow and lower voltage levels within circuits.
[tex]\sf\large\underline\purple{Resistors \:in\: Series:-}[/tex]
[tex]\rightarrow[/tex]A circuit is said to be connected in series when the same amount of current flows through the resistors. In such circuits, the voltage across each resistor is different.
[tex]\rightarrow[/tex]In a series connection, if any resistor is broken or a fault occurs, then the entire circuit is turned off. The construction of a series circuit is simpler compared to a parallel circuit.
[tex]\rightarrow[/tex]For the above circuit(attached image-1), the total resistance is given as:
[tex]\sf{R_{total}\: = \:R1 + R2 + ….. + Rn}[/tex]
The total resistance of the system is just the total of individual resistances.
[tex]\sf\large\underline\purple{Resistors \:in\: Parallel:-}[/tex]
[tex]\rightarrow[/tex]A circuit is said to be connected in parallel when the voltage is the same across the resistors. In such circuits, the current is branched out and recombines when branches meet at a common point.
[tex]\rightarrow[/tex]A resistor or any other component can be connected or disconnected easily without affecting other elements in a parallel circuit.
[tex]\rightarrow[/tex]The figure(attached image -2) above shows ‘n’ number of resistors connected in parallel. The following relation gives the total resistance here

Answer:
In a series circuit, the output current of the first resistor flows into the input of the second resistor; therefore, the current is the same in each resistor. In a parallel circuit, all of the resistor leads on one side of the resistors are connected together and all the leads on the other side are connected together.

A 150- branch in a circuit must be reduced to 93 . A resistor will be added to this branch of the circuit to make this change. What value of resistance should be used and how must the resistor be connected
The value of resistance that should be used is 244.74 Ohms and the resistor must be connected in parallel.
Given the following data:
Initial resistance, R₁ = 150 Ohms.Final resistance, R₂ = 93 Ohms.What is a parallel circuit?A parallel circuit can be defined as an electrical circuit with the same potential difference (voltage) across its terminals.
In order to determine the magnitude of a resistor that should be added to this branch of the circuit, the electrical circuit would be connected as a parallel circuit.
Next, the total effective resistance of this electrical circuit is given by:
RT = (R₁ × R₂)/(R₁ - R₂)
RT = (150 × 93)/(150 - 93)
RT = 13950/57
RT = 244.74 Ohms.

It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously
The sound intensity level of 100 physics professors talking simultaneously is equal to 72 decibel.
Given the following data:
Sound intensity = 52 dB.What is sound intensity?Sound intensity can be defined as a measure of the power of a sound wave per unit area. Thus, sound intensity is a quantity that can be used to measure the energy of sound and its unit of measurement is Watts per square meter.
How to calculate the sound intensity level.Mathematically, sound intensity level is given by this formula:
[tex]\beta = 10 log(\frac{I}{I_{ref}} )[/tex]
Note: The reference value of sound intensity is equal to [tex]1.0 \times 10^{-12}\;W/m^2[/tex]
Thus, the sound intensity for one (1) professor is given by:
[tex]I_1 = 1.0 \times 10^{-12} \times 10^{5.2}\\\\I_1=1.585 \times 10^{-7}\;W/m^2[/tex]
For 100 professors, the sound intensity is:
[tex]I_{100} = 1.585 \times 10^{-7} \times 100\\\\I_{100}=1.585 \times 10^{-5}\;W/m^2[/tex]
Substituting the parameters into the formula, we have;
[tex]\beta = 10 log(\frac{1.585 \times 10^{-5}}{1.0 \times 10^{-12}})\\\\\beta = 10 log(15.58 \times 10^{6})\\\\\beta = 10 \times 7.2\\\\\beta =72\;dB[/tex]

Complete Question:
One physics professor talking produces a sound intensity level of 52 dB. It's a frightening idea, but what would be the sound intensity level of 100 physics professors talking simultaneously?
Answer:
72dB
Explanation:
The sound intensity level of one prof is given, that's your β1 (which is equal to 52dB).
Using the sound intensity level formula:
β1= 10log ([tex]\frac{I}{I_{o} }[/tex]) = 52 dB
*This will be useful later on [even if β1 is known]
Set up the formula for β2 (β2 is going to be the new sound intensity, the one for the 100 profs):
β2 = 10 log( [tex]\frac{ 100 I}{I_{o} }[/tex] )
*You need to multiply the intensity of one professor by 100 (because now there's more)
*do some algebra- pull out the 100
β2 = 10 log (100 [tex]\frac{I}{I_{o} }[/tex])
*use log laws
β2 = 10 ( log(100) + log ([tex]\frac{I}{I_{o} }[/tex]) )
*Now, isn't there a familiar part? Well, yes! The expression for β1!
β2 = 10log(100) + β1
β2 = 10log(100) + 52dB
*use your calculator
β2 = 73dB
^^^ that's your new sound intensity level

four pieces of graph paper a ruler two pencils a helper Follow these steps: Choose which person will be the sender (satellite) and which will be the receiver (television). Each person then draws a 10" by 10" square on a piece of graph paper. Draw a grid within the square, so that each small square of the grid is about 1 inch square. This should give you an area with 100 squares in it. The size of the small squares will depend somewhat on the graph paper used - make sure you use some of the lines on the graph paper as guidelines. The sender now draws a simple picture within the 10" x 10" square without letting the receiver see what he or she is drawing. The sender should now “read” the picture to the receiver, using a digital code. If a square on the graph paper is blank, the sender says “Zero”; if the square is filled in or has any mark in it at all, the sender says, “One.” Using this code, the sender starts with the top row and reads from left to right, one square at a time. The receiver, upon hearing this code, transfers the information to his own graph paper. The receiver must mark the graph paper by starting with the top row of squares and going from left to right. If the sender says “zero,” no mark is made. If the sender says “one,” the receiver should fill in the square completely! At the end of the first row, the sender should say, “End row 1,” and repeat this at the end of each row. At the end of the last row, compare the two pictures. Check the results to see how accurate the transfer was. Now, get two more pieces of graph paper and draw 10” by 10” squares on them. This time, your grid size should be close to 1/4 inch rather than one inch. You will have many more squares than before! You can use the same drawing or switch people and the new sender can draw another picture. Follow the same procedure. Describe your results. Compare the accuracy of the two pictures drawn by the receiver. Which one is more precise
Answer:
is there a picture? so I can understand it more and it will be easier for me to answer. thank you
Answer:
The second one is more accurate because we were able to draw more precisely and accurately, the first picture was more of a general idea of the picture and the second picture was more of a detailed version.

Explanation:
The formula for kinetic energy is [tex]KE = \frac{1}{2}mV^2[/tex], where KE = Kinetic Energy in Joules (J), m = mass in kilograms (kg), and V = Velocity in meters per second (m/s).
In this problem, we are given the Kinetic Energy amount as 193 Joules and the Velocity as 2.54 m/s. Let's plug it into our equation
[tex]193 = \frac{1}{2} * 2.54^2m[/tex]Now, let's solve this equation.
