Hackers use "cross-site scripting (XSS)" to execute arbitrary scripts through the web browser.
Cross-site scripting (XSS) is a type of web vulnerability that allows hackers to inject malicious scripts into web pages viewed by other users. This is done by taking advantage of vulnerabilities in web applications that allow user-generated content to be displayed on web pages without proper validation or sanitization.
Once the malicious script is injected into the web page, it can be executed in the context of the victim's browser, allowing the attacker to perform various unauthorized actions, such as stealing sensitive information (e.g., login credentials, credit card information), modifying web page content, redirecting users to malicious websites, or performing other malicious activities.
XSS attacks can occur in different forms, including stored (persistent) XSS and reflected (non-persistent) XSS. In stored XSS, the malicious script is permanently stored on the server and executed whenever a user requests the infected web page. In reflected XSS, the malicious script is included in the URL or input fields of a web page and is reflected back to the user in the response, causing the script to be executed in the user's browser.
Protecting against XSS attacks involves implementing proper input validation and output encoding in web applications to prevent the injection of malicious scripts into web pages. Web developers should follow secure coding practices and use security mechanisms, such as Content Security Policy (CSP), to mitigate the risk of XSS vulnerabilities. Additionally, web users should be cautious when clicking on links or entering data on web pages, especially those that do not have proper security measures in place.
Hence, hackers use "cross-site scripting (XSS)" to execute arbitrary scripts through the web browser.

Fracture is a direct result of crack propagation in a material. option d
When a crack is present in a material, it acts as a stress concentrator, causing stress to be concentrated at the tip of the crack.
This can lead to the propagation of the crack, resulting in fracture of the material. Fracture can occur in different ways, depending on the material and the conditions under which it is loaded.
For example, in ductile materials, fracture can occur through ductile tearing or shear deformation, while in brittle materials, fracture occurs by rapid crack propagation without significant plastic deformation.

Determine the Fourier series coefficients for each of the following discrete-time peri- odic signals. Plot the magnitude and phase of each set of coefficients ak using MATLAB.
Answer:
As there are no specific signals given in the question, I will provide the general approach to find the Fourier series coefficients for a discrete-time periodic signal.
Suppose we have a discrete-time periodic signal x[n] with period N. Its Fourier series coefficients can be calculated using the following formula:
ak = (1/N) * sum(x[n] * exp(-j2pikn/N)), for k = 0,1,2,...,N-1
where j is the imaginary unit, and * denotes complex conjugation.
To plot the magnitude and phase of each set of coefficients using MATLAB, we can use the following commands:
Ak = abs(ak); % magnitude of coefficients
theta_k = angle(ak); % phase of coefficients
figure; % create new figure
stem(Ak); % plot magnitude
xlabel('k'); ylabel('|Ak|');
figure; % create new figure
stem(theta_k); % plot phase
xlabel('k'); ylabel('theta_k (radians)');
These commands will generate two separate plots, one for the magnitude and one for the phase, with k on the x-axis and |Ak| or theta_k on the y-axis.
what factors does the resistance offered by a piece of conductor depend upon?
The resistance offered by a conductor depends on its length, cross-sectional area, material, and temperature.
1. Length: Resistance is directly proportional to the length of the conductor. As length increases, the resistance increases, because electrons face more obstacles while passing through the conductor.
2. Cross-sectional area: Resistance is inversely proportional to the conductor's cross-sectional area. A larger area allows more electrons to flow through, reducing resistance.
3. Material: Different materials have different resistivities, affecting resistance. Materials with low resistivity, like copper and silver, are good conductors, while those with high resistivity, like rubber, are insulators.
4. Temperature: As temperature increases, so does resistance in most conductors, because increased thermal energy leads to greater atomic vibrations, which impede electron flow.
These factors influence the ease with which electrons can flow through the conductor, ultimately affecting its resistance.

The notches in the decorative pillar create areas of high stress concentration, which weakens the overall strength of the pillar. This is because the notches act as stress concentrators, which causes the material around them to experience more stress than the surrounding areas.
As a result, the decorative pillar will have a lower load bearing capacity compared to a similarly sized pillar made of the same material without notches. The notches can also act as barriers to dislocation motion, but this effect is not strong enough to compensate for the weakening caused by the stress concentration.

The energy residing within the capacitor is effectively equal to 24 microjoules.
How to calculate the energyUsing the formula for capacitance, C = Q/V, where C is represented in Farads and V is distinguished by the voltage across the capacitor, we arrange the equation to obtain V = Q/C. Applying the given values of 0.12 mC & 3 µF culminates in 40 volts as our hypothetical voltage across the 3 µF capacitor.
Furthermore, if our desired outcome is the determinate energy stored within the capacitor, then, in accordance with E = 1/2 * C * V^2 (where E is measured in Joules), substituting the priorly acquired answers results in 24 µJ. Ergo, the energy residing within the capacitor is effectively equal to 24 microjoules.
