Answer: You would need two loops to iterate through both dimensions

Explanation:

matrix = [[1,2,3,4,5],

[6,7,8,9,10],

[11,12,13,14,15]]

for rows in matrix:

for numbers in rows:

print(numbers)

The first loop cycles through all the immediate subjects in it, which are the three lists. The second loop calls the for loop variable and iterates through each individual subject because they are lists. So the first loop iterates through the 1st dimension (the lists) and the seconds loop iterates through the 2nd dimension (the numbers in the lists).

Explanation:

Lighting is one of the key factor which is essential to do cinematography
It will help to cut off the shadows that is created using natural light
It can depict the mood of the scene that is shoot
We can adjust manually brightness and darkness according to the need, which is not possible in the natural light.
It can boost the quality of the footage
We can shoot anytime irrespective of the weather condition

Consider the two computers A and B with the clock cycle times 100 ps and 150 ps respectively for some program. The number of cyc

Kipish [7]

Answer:

Option d) B is 1.33 times faster than A

Given:

Clock time, $t_{A} = 100 ps$

$t_{A} = 150 ps$

No. of cycles per instructions, $n_{A} = 2.0$

$n_{B} = 1.0$

Solution:

Let I be the no. of instructions for the program.

CPU clock cycle, $f_{A}$ = 2.0 I

CPU clock cycle, $f_{B}$ = 1.0 I

Now,

CPU time for each can be calculated as:

CPU time, T = $CPU clock cycle\times clock time$

$T_{A} = f_{A}\times t_{A} = 2.0 I\times 100 = 200 I ps$

$T_{B} = f_{B}\times t_{B} = 1.0 I\times 100 = 150 I ps$

Thus B is faster than A

Now,

$\frac{Performance of A}{Performance of B} = \frac{T_{A}}{T_{B}}$

$\frac{Performance of A}{Performance of B} = \frac{200}{150}$

Performance of B is 1.33 times that of A

Pepsi [2]

Answer:

To solve the problem, first,

a) The computer account should be reset.

b) Deactivate the computer from the domain.

c) Then, rejoin it to the domain.

Explanation:

A domain is a network that allows different computers to function and operate from a common server. A domain may or may not be protected by a password. Setting up a domain provides additional security thereby blocking other computer networks from having access to it. When a person is experiencing difficulties in logging into a domain, there are certain things to be done to resolve the issue.

First, reset the computer account.

Secondly, deactivate the computer from the domain.

Third, Rejoin it back to the domain.
