z1 = 10 z2 = 20 z3 =10 z4 = 20
b. n2 = 600 rpm, n3 = 1200 rpm, n4 = 600 rpm
la relacion de transmision = 2
Explanation:
where z1 = 10, z2 = 20, z3 = 10, z4 = 20
and n1 = 1200 rpm
n2 = n1 * z1/z2 = (1200 * 10)/ 20 = 600 rpm
n3 = n2 * z2/z3 = (600 * 20)/ 10 = 1200 rpm
n4 = n3 * z3/z4 = (1200 * 10)/ 20 = 600 rpm
la relacion de transmision = z2/z1 * z3/z2 * z4/z3
= 20/10 * 10/20 * 20/10 = 2 * 0.5 * 2 = 2

The surface area of each shape
Triangle
[tex]Area = \frac{1}{2}bh[/tex]
[tex]b\to base; h \to height[/tex]
So:
[tex]Area = \frac{1}{2} * 23 * 21[/tex]
[tex]Area = 241.5m^2[/tex]
Square
[tex]Area = l^2[/tex]
[tex]l \to length[/tex]
So:
[tex]Area = 10^2[/tex]
[tex]Area = 100m^2[/tex]
Rhombus
[tex]Area =a^2\sin(\theta)[/tex]
[tex]a \to side\ length[/tex]
[tex]\theta \to any\ interior\ angle[/tex] (not given)
So:
[tex]Area =18^2\sin(\theta)[/tex]
[tex]Area =324\sin(\theta)[/tex]
Trapezium
[tex]Area = \frac{1}{2}(a + b)*h[/tex]
[tex]a,b \to parallel\ sides; h \to height[/tex]
So:
[tex]Area = \frac{1}{2}(18 + 23)*21[/tex]
[tex]Area = \frac{1}{2}*41*21[/tex]
[tex]Area = 430.5m^2[/tex]
Circle
[tex]Area = \frac{\pi d^2}{4}[/tex]
[tex]d \to diameter[/tex]
So:
[tex]Area = \frac{3.14 * 5^2}{4}[/tex]
[tex]Area = \frac{3.14 * 25}{4}[/tex]
[tex]Area = \frac{78.5}{4}[/tex]
[tex]Area = 19.625m^2[/tex]

An attacker has obtained the logon credentials for a regular user on your network. Which type of security threat exists if this user account is used to perform administrative functions
Answer:
privilege escalation.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list (ACL) primarily is composed of a set of permissions and operations associated with a user account or new technology file system (NTFS) file such as full control, read only, write, read and execute and modify.
In this scenario, an attacker or hacker was able to obtain the logon credentials for a regular user on your network. Thus, the type of security threat which exists if this user account is used by the attacker or hacker to perform administrative functions is privilege escalation.
Privilege escalation can be defined as a network or security threat which involves the exploitation of a design flaw, bug or unsecured configuration settings in a software program (application), operating system (OS), computer system, etc., so as to have an unauthorized access and gain more permissions, elevated rights or privileges that are normally protected from a user account or software program.
Hence, when an attacker or malicious user such as a hacker gains an unauthorized access to the privileges of another user account beyond what is intended or entitled to a user, it is known as privilege escalation.

Suppose you are developing a data visualization application DataViz which calls some functions from a statistics library class SuperStats. You recently heard about another statistics library UberStats with supposedly significantly better performance than SuperStats. Explain how you would redesign the DataViz class using the Adapter pattern so that DataViz can be configured at runtime to use either SuperStats or UberStats. Does your design use dependency inversion and/or dependency injection? Explain
Answer:
By using dependency injection, create the adapter to adapt both the DataViz and the UberStats interface as expected.
Explanation:
Adapters are used in Objected-oriented programming to run or convert the output of one class object to another. The DataViz class currently uses the SuperStats class as an adaptee to get and output statistical results.
Write a new code from the scratch is tedious, so, the UberStats class dependencies are injected in the adapter and the DataViz and UberStats class functionalities can be experimented with.

4-5 What are the benefits of grasslands to nature?
paki answer po please
Answer:
1) Grasslands are areas where the vegetation is dominated by grasses. However, sedge and rush can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth.
2) Animals adapt to the shortage of water and food through various ways, including migrating (moving to another area) and hibernating until the season is over. Grazing animals, like gazelles and zebras, feed on grasses and often use camouflage to protect themselves from predators when they are roaming in the open.
3) Grasslands clearly provide the feed base for grazing livestock and thus numerous high-quality foods, but such livestock also provide products such as fertilizer, transport, traction, fibre and leather.
