decision Capital Investment Variable Cost The variable cost of air jet looms is Rs135 per 100m fabric whereas projectile looms variable cost is Rs 55. However‚ the fixed cost for air jet looms is higher that can be minimized by achieving the economies of scale. Maintenance Cost Power Consumption The weft waste in air jet is ranging from 3 to 6 %but projectile looms have no weft waste. Zero percent weft waste not only makes them economically preferable But the 10% higher efficiency

much they weigh. The force of gravity is always acting vertically; there is no horizontal deceleration in the absence of aerodynamic forces. Acceleration is the same regardless of the weight of the implement. Therefore‚ the vertical velocity of a projectile decreases by 9.8 m/s every second. Linear Acceleration Acceleration is a measure of the time rate of change of velocity. Acceleration can be caused by a change in speed or direction or both. For example‚ a skater who goes from a standstill

Device Presentation C.J. Long 4th period 10-10-16 Function of device A shotgun is usually designed to be fired from the shoulder‚ which uses the energy of a shell to fire a number of small spherical pellets called shot. A semi-automatic shotgun is a shotgun that is able to fire a shell after every trigger squeeze‚ without needing to manually chamber another round. This weapon uses gas‚ blowback‚ or recoil operation to cycle the action‚ eject the empty shell‚ and load another shell. When a round is

Physics Stage 6 – Yr 12 Notes 9.2 Space: Context 1 – The Earth has a gravitational field that exerts a force on objects both on it and around it. Define weight as the force on an object due to a gravitational field Mass (m): • The amount of matter in a body • Constant anywhere in the universe • Scalar quantity • Measured in Kilograms (Kg) Weight (W): • The force acting on an object due to a gravitational field • Attractive force • Vector quantity

With David being much closer to Goliath this makes his choice even more deadly; while staying out of range of Goliath’s weapons. Eitan Hirsch backs up this aspect of the battle by conducting calculations with the Israeli defense forces by calculating David would have hit Goliath at 35 meters per second the same power as a modern hand gun (11).

The formula for determining kinetic energy is KE = mv2‚ where KE is kinetic energy‚ m is mass of the projectile‚ and v is velocity. Based on this formula‚ the velocity of a projectile has traditionally been considered far more important than its mass in determining its wounding power. Indeed‚ guns
