The largest binary number that can be expressed with 15 bits is 111111111111111 in binary. The equivalent decimal number is 32767, and the equivalent hexadecimal number is 0x7FFF.

Only the digits 0 and 1 are used to denote binary numbers, which are base-2 numbers. A binary number's digits each represent a power of 2, with the rightmost digit standing in for 20, the next digit for 21, and so on. The binary number's decimal representation is obtained by adding together the values each digit stands for. Each of the 15 digits of the greatest 15-bit binary number is set to 1, hence the decimal equivalent is equal to the sum of the first 15 powers of 2 in this example. A number can also be expressed in a different basis by using the hexadecimal notation, where each digit stands for a distinct power of two.

The number of revolutions that the tires of the automobile with 0.240 m radius tires make after travelling 65,000 km is 43 million.

Given that the radius of an automobile tire is 0.240 m and it travels 65,000 km before wearing them out. We need to find the number of revolutions that the tires make, neglecting any backing up and any change in radius due to wear.

Formula used:

Revolutions (n) = Distance travelled / Circumference of the wheel

Let the distance travelled by the automobile before wearing out the tires be D. According to the problem,

Distance D = 65,000 km = 65,000 x 1000 m = 65,000,000 m

Radius r = 0.240 m

We can find the circumference of the wheel using the formula

Circumference of the wheel = 2πr= 2 × 3.14 × 0.240 m= 1.51 m

Revolution of the wheel = Distance travelled / Circumference of the wheel= 65,000,000 / 1.51= 43,046,358.27≈ 43 million revolutions

Therefore, the number of revolutions that the tires make is 43 million.

Answer:

ICT is the abbreviated form of Information and Communication. It included different technologies like mobile phones, computers, USBs etc.

Following are two precautionary measures which should be observed when using any kind of ICT:

The general solution of the differential equation is: y(x) = y_h(x) + y_p(x) = c1e^(4x) + c2e^(-x) + (10/3)e^(4x).

1. To solve the differential equation (D^4 + 6D^3 + 17D^2 + 22D + 13)y = 0, we can use the characteristic equation method. Let's denote D as the differentiation operator d/dx.

The characteristic equation is obtained by substituting y = e^(rx) into the differential equation:

r^4 + 6r^3 + 17r^2 + 22r + 13 = 0

Factoring the equation, we find that r = -1, -1, -2 ± i

Therefore, the general solution of the differential equation is given by:

y(x) = c1e^(-x) + c2xe^(-x) + c3e^(-2x) cos(x) + c4e^(-2x) sin(x)

To find the specific solution satisfying the initial conditions, we substitute the given values of y(0), y'(0), y''(0), and y'''(0) into the general solution and solve for the constants c1, c2, c3, and c4.

2. To solve the differential equation D^2(D-1)y = 3e^x + sin(x), we can use the method of undetermined coefficients.

First, we solve the homogeneous equation D^2(D-1)y = 0. The characteristic equation is r^3 - r^2 = 0, which has roots r = 0 and r = 1 with multiplicity 2.

The homogeneous solution is given by,  y_h(x) = c1 + c2x + c3e^x

Next, we find a particular solution for the non-homogeneous equation D^2(D-1)y = 3e^x + sin(x). Since the right-hand side contains both an exponential and trigonometric function, we assume a particular solution of the form y_p(x) = Ae^x + Bx + Csin(x) + Dcos(x), where A, B, C, and D are constants.

Differentiating y_p(x), we obtain y_p'(x) = Ae^x + B + Ccos(x) - Dsin(x) and y_p''(x) = Ae^x - Csin(x) - Dcos(x).

Substituting these derivatives into the differential equation, we equate the coefficients of the terms:

A - C = 0 (from e^x terms)

B - D = 0 (from x terms)

A + C = 0 (from sin(x) terms)

B + D = 3 (from cos(x) terms)

Solving these equations, we find A = -3/2, B = 3/2, C = 3/2, and D = 3/2.

Therefore, the general solution of the differential equation is:

y(x) = y_h(x) + y_p(x) = c1 + c2x + c3e^x - (3/2)e^x + (3/2)x + (3/2)sin(x) + (3/2)cos(x)

3. To solve the differential equation y'' - 3y' - 4y = 30e^(4x), we can use the method of undetermined coefficients.

First, we solve the associated homogeneous equation y'' - 3y' - 4y = 0. The characteristic equation is r^2 - 3r - 4 = 0, which factors as (r - 4)(r + 1) = 0. The roots are r = 4 and r = -1.

The homogeneous solution is

given by: y_h(x) = c1e^(4x) + c2e^(-x)

Next, we find a particular solution for the non-homogeneous equation y'' - 3y' - 4y = 30e^(4x). Since the right-hand side contains an exponential function, we assume a particular solution of the form y_p(x) = Ae^(4x), where A is a constant.

Differentiating y_p(x), we obtain y_p'(x) = 4Ae^(4x) and y_p''(x) = 16Ae^(4x).

Substituting these derivatives into the differential equation, we have:

16Ae^(4x) - 3(4Ae^(4x)) - 4(Ae^(4x)) = 30e^(4x)

Simplifying, we get 9Ae^(4x) = 30e^(4x), which implies 9A = 30. Solving for A, we find A = 10/3.

Therefore, the general solution of the differential equation is:

y(x) = y_h(x) + y_p(x) = c1e^(4x) + c2e^(-x) + (10/3)e^(4x)

In conclusion, we have obtained the solutions to the given higher-order differential equations and determined the specific solutions satisfying the given initial conditions or non-homogeneous terms.

The instantaneous rating of a fuse refers to the maximum current level at which the fuse will blow and interrupt the circuit almost instantaneously. It is an important parameter to consider when selecting a fuse for a specific application.

The instantaneous rating of a fuse is determined by several factors, including the fuse's design, construction materials, and thermal properties.

The instantaneous rating of a fuse is influenced by its ability to handle high levels of current without overheating. When a current higher than the fuse's rating flows through it, the fuse quickly heats up due to the resistance of the fuse element. This rise in temperature triggers a thermal response, causing the fuse element to melt or blow, breaking the circuit and protecting the connected devices.

The instantaneous rating depends on the fuse's design parameters, such as the size and material of the fuse element, as well as the fuse's thermal characteristics. Fuses are typically designed to have specific current ratings, which indicate the maximum safe current level that the fuse can handle without blowing.

It's important to select a fuse with an instantaneous rating that is appropriate for the expected current levels in the circuit. Choosing a fuse with a higher instantaneous rating than necessary may result in delayed response times, potentially leading to damage or failure of the protected equipment.

The traditional approach to network design involves designing a network from scratch, taking into consideration all the necessary components such as hardware, software, and network protocols.

This approach requires a deep understanding of network architecture and infrastructure and can be time-consuming and complex. On the other hand, the building block approach to network design involves using pre-built components to create a network. This approach involves selecting pre-configured hardware and software that fit the needs of the organization and integrating them into the existing infrastructure. This approach is generally faster and less complex than the traditional approach.

The key difference between these two approaches is the level of customization and control. With the traditional approach, the organization has complete control over the network design and can customize it to meet specific requirements. However, this approach is often more expensive and time-consuming. The building block approach, on the other hand, offers less customization but is more cost-effective and faster to implement. Ultimately, the approach that an organization chooses will depend on its specific needs and budget.
