Crown correct answers A crown is the very tip of the bore in which the exit plane is precisely ma- chined perpendicular to the bore axis Harmonics correct answers Barrel harmonics is the mea- sure of a barrel's ability to return to true upon fir- ing a round, and ensures that from shot to shot, a consistent barrel movement is achieved. Bedding and Stabilizing. correct answers Bedding is a process in which the stock and tang are infused with epoxy that surrounds the action and bar...

The graphs of the following equations are drawn: 1. y = 3x - 2 2. y = x^2 3. y = 1 - x^2 4. y = x + 6 3 and 4 An ore of lead contains 70 % of PbS. Calculate the mass of lead that can be extracted from 478k of the ore. (Ar: Pb = 207; S = 32) A - 28.98kg B - 41.4 kg C - 144.9 kg D - 289.8 kg E - 414.00kg Answer: 478 x 0.7 = 334.6 mass of PbS 334.6 / (207+32) = 1.4 = no. of moles of PbS 1.4 x 207 = 289.8 kg = mass of lead Therefore D is the answer. The energy in joules...

The Circle Formula - ANS-(x - a)² + (y - b)² = r² Where (a,b) is the centre and (x,y) is any point on the circle. The Discriminant - ANS-b² - 4ac Where 0 gives a tangent (repeated root); > 0 gives two real roots; < 0 gives no real roots; d²y/dx² > 0 = minimum point SUVAT - ANS-v = u + at s = ut + 0.5at² v² = u² + 2as s = vt - 0.5at² s = 0.5t(u + v) Product Rule - ANS-dy/dx = u(dv/dx) + v(du/dx) Quotient Rule - ANS-dy/dx = (v(du/dx) - u(dv/dx)) / v² Where the ori...
