Explain in detail how we could collect solar energy from space and get it to earth
Answer: Reflectors or inflatable mirrors spread over a vast swath of space, directing solar radiation onto solar panels. These panels convert solar power into either a microwave or a laser, and beam uninterrupted power down to Earth. On Earth, power-receiving stations collect the beam and add it to the electric grid.

6. A small design agency you are consulting for will be creating client websites and wants to purchase a web server so they can host the sites themselves. How will you advise them on this purchase?
Answer:
Explanation:
The best way to advise the agency in this matter would be to help them completely understand the total cost of ownership of the server. This includes the server itself but many other factors as well. Such as any and all server software and application software that they will need, an IT server manager, facility costs, security costs, backup features. These are some of the main costs that they will be incurring but there may be more unforeseen costs. Therefore the best way to advise them is by providing all of this information so that they can make the most informed decision possible.
Sarah works in a coffee house where she is responsible for keying in customer orders. A customer orders snacks and coffee, but later, cancels the snacks, saying she wants only coffee. At the end of the day, Sarah finds that there is a mismatch in the snack items ordered. Which term suggests that data has been violated?
Answer:
Stack
Explanation:
Stack is a linear data structure that follows a particular order in the way an operation is done or sequence a job is completed.
It uses either LIFO ( Last In, First Out) which is also known as first come first served sequence or FILO (First In, Last Out) sequence.
There are several real life examples of which we can use the example of replacing the snack items Sarah brought for the customer.
If Sarah used the LIFO method, it means she replaced the snack items first ontop of the already existing snack items that's why there is a mismatch.

Answer:
About 5 years ago my girlfriend and I were taking a summer camping trip in southern Alberta. I was in the passenger seat trying to find the campground on a map when she drove over the crest of a hill, was blinded by the sun drove into the ditch. It was a seriously steep ditch but we weren't going very fast so all was fine. I looked over at her and laughed before returning my attention to the map, assuming she could safely bring the vehicle back onto the road.
The next thing I knew, the SUV launched onto the pavement and she lost control and we began swerving. I remember feeling the wheels on the driver's side lift off the ground, then the impact as I was slammed into the door and glass exploded into my face. We barrel rolled and we rolled over-front for a seriously long way.
At some point during the chaos I looked over at her to make sure she was "ok", and just as I did so I watched as she was thrown into the ground through her door window and the corner of the roof just above her seat was crushed inward. The way it looked to me was that she had just been crushed between the ground and the roof of the vehicle. I passed out at that point.
When I came to I had somehow already unbuckled myself from my seat and the vehicle was on its roof. I crawled over to her seat and was in absolute shock to see that she was still in one piece. I removed her from her seat and got us out through the windshield before carrying her for about a half a kilometer down the road, still in shock and fueled entirely by adrenaline.
We were found by a driver who had gone past the wreckage and we were eventually taken to a hospital. I broke 3 ribs on my right side and dislocated my right shoulder, she was severely concussed and scraped up but otherwise mostly okay. However she was 7 weeks pregnant at the time and we found out while in hospital that her body had rejected it under the immense and sudden stress.
We are still together and have 3 amazing and beautiful children, but she still holds onto a lot of guilt surrounding the accident and the loss.

So I have an hp laptop that I have a year with and everything was working great until a month ago when it started saying that the battery couldn’t hold charge anymore.
Since I didn’t want to buy a battery I simply started using while connected with the charger.
But after a few days of saying the battery couldn’t hold charge out of a sudden when I tried connecting my mouse or controller it would recognized.
It passed power to whatever I connected to it but it simply wouldn’t work.
Can it be fixed?
Or do I have to buy a new one.
Answer:If your notebook computer battery does not power the notebook or will not hold a charge, troubleshoot the battery to see if it needs to be replaced. If the battery indicator LED, located near the power icon, does not glow or always blinks, there is a battery problem. Your computer might operate correctly when it is connected to the power adapter, but not when using battery power.

int[] vals = {7,5,3,9,0,37,93,16,68,6,99};
System.out.println(vals[vals[1]+vals[4]]);
Answer:
37
Explanation:
Given int[] vals = {7,5,3,9,0,37,93,16,68,6,99};
In programming, the position of each value in the list are known as index. The first value is always assigned index of 0 not 1, the second value is assigned index of 1 and so on. For example;
val[0] = 7 i.e value with index 0
val[1] = 5
val[4] = 0
In order to print out this value
System.out.println(vals[vals[1]+vals[4]]);
Substituting the index value val[1] and val[4] into the argument given
vals[vals[1]+vals[4]]
= vals[5+0]
= vals[5]
= 37 (value at the 5th index)
System.out.println(vals[vals[1]+vals[4]]);
= 37
This means that the system will print out 37 to the console

Explanation:
An encryption system works by shifting the binary value for a letter one place to the left. "A" then becomes: 1 1 0 0 0 0 1 0 This binary value is then converted to hexadecimal; the hexadecimal value for "A" will be:
Answer:
The hexadecimal equivalent of the encrypted A is C2
Explanation:
Given
Encrypted binary digit of A = 11000010
Required
Hexadecimal equivalent of the encrypted binary digit.
We start by grouping 11000010 in 4 bits
This is as follows;
1100 0010
The we write down the hexadecimal equivalent of each groupings
1100 is equivalent to 12 in hexadecimal
So, 1100 = 12 = C
0010 is represented by 2 in hexadecimal
So, 0010 = 2
Writing this result together; this gives
1100 0010 = C2
Going through the conversion process;
A is first converted to binary digits by shifting a point to the left
A => 11000010
11000010 is then converted to hexadecimal
11000010 = C2
Conclusively, the hexadecimal equivalent of the encrypted A is C2

Cell phones have less command functions than a PC's keyboard and considerably less storage space. Some cell phones may be used as a GPS device
Consider sending a 1,600-byte datagram into a link that has an mtu of 500 bytes. suppose the original datagram is stamped with the identification number 291. how many fragments are generated? what are the values in the various fields in the ip datagram(s) generated related to fragmentation?
Explanation:
Step one
The maximum size of data field in each fragment = 480
(because there are 20 bytes IP header) Thus the number of required
fragments [tex]=\frac{1600-20}{480} \\\\= \frac{1580}{480} \\\\=3.29\\\\[/tex]
thus the number of required fragment is 4
Step two
Each fragment will have identification number 291. each fragment except the last one will be of size 500 bytes (including IP header). the offset of the fragments will be 0, 60, 120, 180. each of the first 3 fragments will have
flag = 1; the last fragment will have flag =0
Using the appropriate formula, the number of fragments which would be present in the datagram to be sent would be 4
The minimum length of IP header = 20 bytes
Maximum transmission unit (mtu) = 500 bytes
Hence, the payload would be calculated thus :
mtu - header ;Payload = 500 - 20 = 480Hence, the maximum size of data field per Fragment = 480 bytes
The number of fragments required :
[tex]\frac{datagram \: size - Header \: size}{payload} [/tex][tex] Number \: of \: fragments = \frac{1600 - 20}{480} = 3.29[/tex]
Hence, the number of fragments is 4
Size per Fragment would be 500 bytes each ; the last Fragment would be about 100 bytes Each Fragment would bear the identification number 291.Learn more : https://brainly.com/question/16289731

Explain how Steve Jobs created and introduced the iPhone and iPad.
Answer:Today, we're introducing three revolutionary products. The first one is a widescreen iPod with touch controls. The second is a revolutionary mobile phone. And the third is a breakthrough Internet communications device. So, three things: a widescreen iPod with touch controls, a revolutionary mobile phone, and a breakthrough Internet communications device. An iPod, a phone, and an Internet communicator. An iPod, a phone...are you getting it? These are not three separate devices. This is one device. And we are calling it iPhone. Today, Apple is going to reinvent the phone.
Late last year, former Apple engineer Andy Grignon, who was in charge of the radios on the original iPhone, gave behind-the-scenes look at how Apple patched together demos for the introduction, with Steve Jobs showing off developmental devices full of buggy software and hardware issues. The iPhone team knew that everything had to go just right for the live iPhone demos to succeed, and they did, turning the smartphone industry on its head even as Apple continue to scramble to finish work on the iPhone.
Apple had actually been interested first in developing a tablet known as "Safari Pad", but as noted by a number of sources including Steve Jobs himself, the company shifted gears once it became clear how revolutionary the multi-touch interface developed for the tablet could be for a smartphone. Apple's tablet wouldn't surface until the launch of the iPad in 2010, three years after the introduction of the iPhone.
Seven years after the famous Macworld 2007 keynote, the iPhone has seen significant enhancements in every area, but the original iPhone remains recognizable as Apple has maintained the overall look of a sleek design with a larger touchscreen and a single round home button on the face of the device.

Answer:
The most common size for desktop hard drives is 3.5 inches, they tend to be faster and more reliable, and have more capacity. But they also make more noise.
Explanation:
If you are continually deleting and installing programs or creating content, the disc must have good reliability.
Keep in mind that larger hard drives are also a little slower, so it is preferable to opt for two smaller ones. Large hard drives are partitioned so there is no problem gettin
chbdg good performance, but if you put everything on one big disk and it breaks, you will lose everything.
If you buy 2 small disks, check that the motherboard does not limit the speed of a second hard disk.

Which jobs are most likely to be replaced by robots and what effect will this have
Answer:
Here we go. Generally the robots are designed in order to do the work which has very much risk and Humans find it too laborious or hard to do. The robots will be used for the army, or as laborers. In my country Nepal, there's a restaurant where robots are used as waiters. They take order from you and provide you the food. The robots can be used for various purposes but I don't think they will be appointed for the job of higher authority. The use of robots will have massive effect in human life. The use of robots and appointing them in various jobs will cause the problem of unemployment. The poor will be affected and their existence may get into problem. This is one effect but there can be many effects from the use of robots. Using robot in army can reduce human deaths but also people get unemployed. There is both advantage and disadvantage from their use.
Don is creating a very long document, and he would like to create an introductory page that contains the title of the document and the name of the author along with the date.
Answer:
This is a very good choice, to do so Don can insert a cover page. He can go to the options menu, pick the "insert" lash, and then to the "pages" square in the far left of the toolbox. There he will find a "cover page" section that will automatically add a cover page at the beginning of the document.
Explanation:
The reasons for this answer are that in the first place, it is very difficult to go o the first page of the document and move everything down because the format would be lost. Then, he would require to edit everything. It would also result in the same in case he only added a white page and started writing. So he needs a specific object that wouldn't damage the format if edited on the first page.
