Electronegative gases are gases that have a higher electron affinity, which means they have a greater tendency to attract and hold onto electrons. Examples of electronegative gases include chlorine, fluoride, and oxygen.

The breakdown strength, or the electrical field strength required to cause electrical breakdown in a gas, is higher in electronegative gases compared to other gases because the electronegative atoms or molecules in these gases can more readily capture free electrons and form negative ions. This reduces the number of free electrons available for conduction, making it more difficult for an electrical breakdown to occur.

Anode streamers are luminous discharges that occur in electrical breakdown in gases and that originate from the anode, or the positively charged electrode. Cathode streamers are similar discharges that originate from the cathode, or the negatively charged electrode. They are caused by the ionization of the gas and the movement of electrons in the electric field. These streamers are responsible for the initiation of the electrical breakdown.

The IP (Integer Programming) problem can be formulated as follows:

Maximize: 2x1 + 5x2

Subject to:

3x1 + 6x2 <= 120 (Constraint on the availability of raw materials)

x1, x2 >= 0 (Non-negativity constraint)

x1, x2 are integers (Integer constraint)

Where x1 is the number of units of product 1 produced, and x2 is the number of units of product 2 produced.

The objective function represents the profit earned by producing x1 units of product 1 and x2 units of product 2. The first constraint represents the availability of raw materials, which limits the production of the products based on the number of units of raw materials required. The non-negativity constraint ensures that the number of units produced is non-negative and the integer constraint ensures that the solution must be in integer.

In regards to the above, If any of product 1 is produced, a setup cost of $10 is incurred, and if any of product 2 is produced, a setup cost of $20 is incurred. The objective function can be adjusted to include these costs as follows:

Maximize: 2x1 + 5x2 - 10y1 - 20y2

Subject to:

3x1 + 6x2 <= 120 (Constraint on the availability of raw materials)

x1 - y1 = 0

x2 - y2 = 0

x1, x2, y1, y2 >= 0 (Non-negativity constraint)

x1, x2, y1, y2 are integers (Integer constraint)

Where y1 is a binary variable that indicates whether product 1 is produced (y1 = 1) or not (y1 = 0) and y2 is a binary variable that indicates whether product 2 is produced (y2 = 1) or not (y2 = 0). This constraints ensure that y1 and y2 are either 0 or 1.

Therefore, the IP model can then be solved using an optimization software to determine the optimal number of units of each product to produce in order to maximize profits.

A steel cable is slowly pulled up a steeply inclining track by a car that weighs 130kN when fully loaded; (b) the maximum allowable incline angle is 30°.

The maximum angle of incidence where the medium (typically air) meets the core (n1) is known as the acceptance angle () for an optical fibre. This angle determines how light enters and travels along the optical fibre. The optical fiber's numerical aperture is the sine of the acceptance angle.

The acceptance angle, which is calculated as the acceptance cone's half-angle, serves as a gauge of a fiber's capacity to gather light (the maximum cone of light that can enter or exit the fiber.) Be aware of what follows: The acceptance cone is triangular in shape.

The NA is related to the cutoff angle, which is the maximum acceptance angle (max) (Figure 1).

Bernoulli's principle may be theoretically understood as the idea that a fluid moving from a high pressure to a low pressure area would accelerate as a result of the net force acting in the direction of motion. To keep the top plate moving at a constant speed U, the system has to be subjected to a shear stress, t = (F/A).
