1. Why is photographing lightning a difficult process?
Some reasons which come to my mind for saying this are: 1) You get only one chance for the particular situation - it is not like portrait photography where you can go back in the studio if the photos didn't come out well; 2) lightning varies so much in brightness, intensity and location that guessing the proper exposure requires a lot of experience, as well as luck; 3) you are always at some risk when photographing worthwhile lightning; and 4) lightning is a point (line) source, and demands the most of the optical quality of your camera

2. What piece of equipment is helpful in capturing lightning photographs?
SLR camera with B-shutter speed (preferably SLR; you might try using your digital camera, if it has B mode, but this is much more difficult)lenses ranging from 28mm to 135mm at minimum. Fixed-focal lenses are preferred over zoomlenses. Aperture ranges should be f/2.8 - f/22.sturdy tripod (metal or plastic doesn't make any difference whatsoever at all in safety - if lightning is so close by, you are in trouble anyway)cable release, which can be lockedSlow-speed film: 100 or 200 ISO

3. Why is it important to mentally prepare for photographing lightning?
When photographing lightning, it’s important to realize that the conditions you are shooting in are unpredictable and dangerous, and there will always be an element of chance and luck involved. So you should prepare yourself.

4. What time of day should you try to photograph lightning?
Nighttime lightning photography is the easiest type

5. Why is composition important in lightning photographs?
It boosts or adds drama to your picture.

a password to a certain database consists of digits that cannot be repeated. if the password is known to consist of at least 8 d

BaLLatris [955]

Answer:

$\frac{10!}{2}mins$

Explanation:

12 seconds to try one combination will be equivalent to $\frac{1}{12}\times 60 = \frac{1}{5} \ mins$

Password contain at least 8 digit i.e. password can contain 8, 9, 10 digit.

Password cannot contain more than 10 digit because it will give room for repetition which it is clearly stated that digit cannot be repeated.

Possible digit that can be used: 9,8,7,6,5,4,3,2,1,0.

Total number of passwords combination possible for each position in 8 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3. Total number of passwords combination possible in 8 digit is equivalent to $\frac{10!}{2}$ .

Total number of passwords combination possible for each position in 9 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2. Total number of passwords combination possible in 9 digit is equivalent to $\frac{10!}{1}$ .

Total number of passwords combination possible for each position in 10 digit.

1st position = 10, 2nd position = 9, 3rd position = 8, 4th position = 7, 5th position = 6, 6th position = 5, 7th position = 4, 8th position = 3, 9th position = 2, 10th position = 1. Total number of passwords combination possible in 10 digit is equivalent to 10!.

Adding them up and multiplying by $\frac{1}{5} \ mins$ to get the total number of time needed to guarantee access to database = $[\frac{10!}{2}\times\ \frac{10!}{1} \times 10!] \frac{1}{5}\ mins = \frac{10!}{2}$

Alex

Following actions could you most likely advise the client taking to strengthen the security of their wireless network-

Change the default SSID to anything different.
Turn off SSID broadcasting.

<h3>Explain the term wireless network security?</h3>

Designing, putting into practice, and ensuring security on such a wireless computer network are all parts of wireless network security.
A wireless computer network is further protected by this subset of network security.
Wireless security is another name for wireless network security.

For the stated question-

Disabling SSID broadcast and changing the network name are advised.
By disabling SSID, the network name won't be displayed on devices looking for a network can connect to, and so by changing the name, it will be impossible for anyone who already knows the old name to connect.
Both of which significantly boost security.
