What lenses cannot be changed to focus on items closer or farther away?
Answer:
Fixed focus lenses
Explanation:
What lenses cannot be changed to focus on items closer or farther away?
Zoom lenses
Autofocus lenses
Fixed focus lenses
Stationary lenses
Fixed focus lenses are lenses for taking pictures that are used in cameras, that have a fixed focus, meaning that the focus on the image will be always located in the same spot and al of the other areas will look blurry to the sight, they can not change the focus to objects closer or further away, if you wich to focus something that is closer to the camera you need to back up witht eh camera and find the spot where the lens focuses on the object, so that would be the answer.
A computer has a word length of 8 bits (including sign). if 2’s complement is used to represent negative numbers, what range of integers can be stored in the computer? if 1’s complement is used? (express your answers in decimal.)
The word length of a computer is simply the number of bits, the computer can process
The word length is given as:
[tex]n = 8[/tex]
(a) 2's complements
The smallest integer in the 2's complement is::
[tex]N= -(2^{n-1})[/tex]
While the largest integer is:
[tex]N= 2^{n-1} -1[/tex]
So, we have:
[tex]Smallest = -(2^{8-1})[/tex]
[tex]Smallest = -(2^7})[/tex]
[tex]Smallest = -128[/tex]
And the largest is:
[tex]Largest= 2^{8-1}-1[/tex]
[tex]Largest= 2^{7}-1[/tex]
[tex]Largest= 128-1[/tex]
[tex]Largest= 127[/tex]
Hence, the computer can store all integers from within an inclusive range of -128 to 127, using the 2's complement
(b) 1's complements
The smallest integer in the 1's complement is::
[tex]N= -(2^{n-1}) + 1[/tex]
While the largest integer is:
[tex]N= 2^{n-1} -1[/tex]
So, we have:
[tex]Smallest = -(2^{8-1})+1[/tex]
[tex]Smallest = -(2^7})+1[/tex]
[tex]Smallest = -128+1[/tex]
[tex]Smallest = -127[/tex]
And the largest is:
[tex]Largest= 2^{8-1}-1[/tex]
[tex]Largest= 2^{7}-1[/tex]
[tex]Largest= 128-1[/tex]
[tex]Largest= 127[/tex]
Hence, the computer can store all integers from within an inclusive range of -127 to 127, using the 1's complement

Explanation:
The truth is, hiring a professional web designer or design firm is not for everyone.
If you’re a new business without much revenue, then using an affordable website builder is exactly what you should be doing.
However, if you own a small or medium sized business, using a ‘free’ website builder could cost your company many tens of thousands of dollars in wasted man hours and even more money in the opportunity cost of lost potential revenue.
In this article, we will address several aspects of the debate, “web designer vs website builder?” Who would be better off hiring a professional and the specific advantages and disadvantages of doing either?

Look at the simple circuit illustrated in the figure above. What will happen when only switch S1 is closed?
A. No current will flow in the circuit.
B. Nothing will happen; the light bulb won't light up.
C. The light bulb will light up.
D. The resistance of the circuit will increase.
Answer: A. No current will flow in the circuit.
Explanation:
The Figure 1 illustrates the equivalent circuit at only switch S1 closed. That is a series circuit with two diodes, a bulb, and a battery.
Suppose that there is a current flowing in the circuit. A current flowing in the circuit implies that D1 is on. If D1 is on, there should be 0.7 V between anode and cathode (see Figure 2 left). However, there is not possible a low voltage on the top and a high voltage at the bottom of D1 (see Figure 2 right). Then, it is not viable 0.7 V between anode and cathode of diode D1. Therefore, D1 is off.
Now, we already know that this is a series circuit with the diode D1 off, so we can conclude that no current will flow in the circuit.
Correct answer is A. No current will flow in the circuit.
There isn't current flowing in the circuit next the light bulb won't light up. But other things happen, for example, the high voltage goes to the light bulb at only switch S1 closed. we can say that option B. is partially wrong and options C. is wrong
Finally, there are no resistances in the circuit. So, option D. is not right

Class sizes of various sections of college algebra at your university are an example of which type of data? quiizlet
Class sizes of various sections of college algebra at your university are an example of quantitative data, specifically discrete quantitative data.
Explanation:The class sizes of various sections of college algebra at your university are an example of quantitative data. Quantitative data represents numerical values that can be measured or counted.
Specifically, the class sizes can be represented as discrete quantitative data, as the number of students in each section is a whole number value. For example, one section may have 30 students, another section may have 25 students, and so on.
