Quantitative Conservation of Momentum Name: ______________________________________ 1. Kim holds a 2.0 kg air rifle loosely and fires a bullet of mass 1.0 g. The muzzle velocity of the bullet is 150 m/s. Find the recoil speed of the gun. Momentum conservation equation: Recoil speed =________________ 2. If the girl in the previous question holds the gun tightly against her body‚ the recoil speed is less. Calculate the new recoil speed for the 48 kg girl. Momentum conservation equation:

It also aimed to use crude extract as fuel for lighting purposes. The study was limited to the extraction of crude from yellow bell seeds and its possible use as fuel for lighting purposes. The extraction did not use any organic solvent—only water. Chemical analysis of the crude extract was not done. There was no statistical treat-ment needed‚ only the

Energy Conservation 1 Energy conservation is the reduction or elimination of unnecessary energy use and waste. This practice may result in increase human comfort‚ personal security‚ national security‚ environmental value‚ and financial capital. There are many activities that people can do to conserve energy and help not only themselves‚ but also the environment and everyone around them. Conserving energy is important because most of our current energy sources are not renewable. When using

industrial as well as municipalities (Geurrero & Amosson‚ 2013). Lack of water regulation and conservation initiatives over the years combined with population growth‚ a longer life span‚ and drought has caused the depletion of aquifers to an alarming point (Somma‚ 1997). New regulations are vital for the allocation of water to support the various industries. However‚ they must involve new methods of water conservation to enable the aquifers to replenish naturally from the absorption of runoff and surface

Preservation and conservation – these two words strive toward the same purpose using different methods. However‚ to understand each methodology‚ people need to understand the definition of the words. Preservation means maintaining natural resources by not using them and preventing human interference as much as possible. Alternatively‚ conservation allows a controlled usage of natural resources while maintaining the sustainability of those resources for future generations. People frequently use the
