Answer:

ARPANET

Explanation:

ARPANET

The correct option that explains the reason why the moon will have greater effect on the tides compared to the sun is;

Option D; The moon is closer to the Earth

• Generally speaking, ocean tides on the earth are caused by both the gravity of the moon and the gravity of the sun.

Now, the mode of generation of ocean tides is not really by the total strength of gravity, but rather by the gravitational gradient.

Gravitational gradient is simply defined as the gravity differences from one spot to the other.

• Now, from research, we know that the sun is far larger than the moon and this means in consequence it will have a far stronger total gravity than that of the moon. However, due to the fact that the moon is closer to the earth than the sun, it means the moon would possess a stronger gravitational gradient than which the sun possesses.

• Now, let's get to ocean tides; The ocean tides arise as a result of the response of ocean water to a gravitational gradient and as a result, the moon will have a greater role in creating tides than that which the sun does.

Answer: Amazon Aurora

Explanation:

Amazon Aurora is a fully managed service which is vital in saving time through the automation of time consuming tasks like recovery, backup, provisioning, patching, repair, and failure detection.

Amazon Aurora also allows the encryption of databases through the use of keys that are managed through the AWS Key Management Service. Therefore, based on the information given the question, type of database service that the Architect should use is Amazon Aurora.

Answer:

Explanation:

For the Program plan:

1. Two lists are structurally equal if they have the same list structure, although their atoms may be different.

2. So we are going to write a function that will check if elements in both lists at same position are atoms or not.

3. If yes then it should return true else false.

Program:

#lang scheme

( define (structurally-equal list1 list2)

(cond ((and (null? list1) (null? list2)) #t)

((or (null? list1) (null? list2)) #f)

((and (atom? (car list1)) (atom? (car list2)))

(structurally-equal (cdr list1) (cdr list2)))

((or (atom? (car list1)) (atom? (car list2))) #f)

(else (and (structurally-equal (car list1) (car list2))

(structurally-equal (cdr list1) (cdr list2) )))))

( define (atom? x) (not (or (pair? x) (null? x))))

1. Increase QoS

Explanation:

The radio bands with lower frequency have relatively large wavelengths that are not as affected by objects such as building, trees, weather events or other features in the troposphere as the higher frequency radiation. General rule for radiation is that the lower the frequency, i.e. the longer the wavelength, the further a signal can penetrate through solid objects or liquids. Hence, when the frequency is lowered on a wireless access point, the signals can travel farther and smoother. Thus, increasing the quality of service.
