The general wave equation is given by Y = sin A 2π/λ [x - vt] = Sin A [(2π X)/λ - (2π vt)/λ] thus if A = 0.15;λ = 0.01m; f = 550Hz then V = f x λ = 550 x 0.01 = 5.50m/s ∴ Y = 0.15 sin [(2 x λ x X)/0.01 - (2 x λ x 5.5t)/0.01] = 0.15 sin[200λX - 200 x λ x 5.5t] ∴ Y = 0.15 sin 200λ[x - 5.5t]

For transverse wave on string velocity V = \(\sqrt{\frac{T}{M}}\) where T is the tension, and M is the mass per unit length ∴ for T = 12N and M = 3.0 x 10\(^{-2}\)kgm\(^{-1}\) V = \(\sqrt{\frac{12}{3.0 \times10^{-2}}}\) V = \(\sqrt{\frac{1200}{3}}\) = \(\sqrt{400}\) ∴ V = 20m/s

Angle of deviation = 180 - [i + v] = 180 - 2i [since i = v] ∴ 120 = 180 - 2i 2i = 180 - 120 = 60 ∴ i = 30o

The Six's maximum and minimum thermometer uses a liquid-filled bulb connected to a U-shaped tube with a mercury thread. As the liquid expands or contracts, the mercury moves, pushing the steel indexes to indicate the maximum and minimum temperatures, which can be reset using a magnet.

Since capacitance C = Q/V, => Q = CV ∴ Qp = 5 x 10\(^{-6}\) x 20 = 100 x 10\(^{-6}\) or 100\muC Qp = 10 x 10\(^{-6}\) x 20 = 200 x 10\(^{-6}\) or 200\muC Correct option 100\muC and 200\muC

As the light enters the dense medium, the shorter wavelengths (blue and violet) bend more than the longer wavelengths (red and orange), resulting in the separation of the light into its component colors. Based on this, the correct representation is: > Ray a represents the red color > Ray b represents the green color > Ray c represents the blue color

Effective resistance in the circuit = 3 + 2 + 1 = 6\Omega Current through the I = \(\frac{E}{(R+r)}\) ∴ I = \(\frac{2}{6}\) => V1 = I x R1 = \(\frac{2}{6}\times\frac{3}{1}\) = 1V = V2 = I x R2 = \(\frac{2}{6}\times\frac{2}{1}\) = \(\frac{2}{3}\)V ∴ we have 1V and \(\frac{2}{3}\)V

In the provided circuit diagram, the correct position for a fuse is between the "Line" connection and the component labeled "P". The purpose of a fuse is to protect the circuit and the connected device from excessive current flow that could potentially cause damage. By placing the fuse at position P, it will be in series with the "live" or "hot" wire, allowing it to interrupt the circuit if the current exceeds the fuse's rated capacity.

Impedance Z = \(\sqrt{R^2 + X^2}\) = \(\sqrt{(30)^2 + (40)^2}\) ∴ Z = \(\sqrt{2500}\) = 50\(\Omega\) But current I = \(\frac{V}{Z}\) = \(\frac{200}{50}\) = 4.00 A

In general, gases conduct electricity under reduced pressure and high voltage/potential. But from Ohms Law, current is directly proportional to voltage. Thus high current presupposes high voltage.

The phrase "numbed sensitivity" refers to a diminished emotional response or a deadening of the ability to feel or react appropriately to violence due to its frequent portrayal in media. This suggests that constant exposure to violent acts in films and television can desensitise viewers and make violence seem less shocking.

The premise of education in the passage is that good models influence the young. From this, the author builds an argument to suggest what this premise implies—that bad models (like violence on TV) can negatively influence behaviour. Given this, the correct interpretation of what the premise proves in the context of the passage is that violence on television encourages violence in real life. This conclusion is drawn because if good models positively influence the young (the premise), then bad models, such as fantasized violence, likely have a harmful impact, including encouraging violence in real life.

The passage states that "The chance that a black male between the ages of 15 and 19 will be killed by a gun has almost tripled since 1985". This indicates that the number of deaths among this group has significantly increased.

The phrase "the firearms figures are rising" means that the number of teenagers killed by firearms is increasing over time. The passage paints a picture of a troubling trend in firearm-related deaths among teenagers and suggests that there are more deaths now compared to previous years.

The passage cites Health and Human Services Secretary Donna Shalala's description of the statistics regarding teenage gun deaths as "frightening and intolerable." This is a strong emotional response to the statistics and indicates that the situation is both alarming (causing fear or concern) and unbearable (something that is too painful or distressing to accept).
