opinions on the issue of the “Tar sands” or “Oil sands” (I shall use both unambiguously) development. Environmentalists (like myself) and concerned citizens in Canada‚ as well as the international community‚ decry that the largest industrial energy project on the face of the planet is destroying future generation’s right to clean soil‚ water‚ air‚ biodiversity and most importantly a stable climate. As well as strong local economy‚ the current economic setup of the tar sands’ development is to focus on

Lab: Electrostatic Coulomb Constant Rylee Rose Date: 1/28/13 Abstract: This experiment was done to study electrostatic and Coulomb’s law. Objective: The objective was to demonstrate the veracity of Coulomb’s Law. This was done by observing different equilibrium conditions of two pith balls that were equally charged. They were then constructed into a pendulum using strings. Calculations were done to determine the charge on pith balls‚ calculate the mass of the pith balls and to calculate

The shortage of natural sand makes the artificial sand necessary. For the production of artificial sand‚ Hongxing Machinery exports remind you that choosing a right sand production process for artificial sand is just like water for fish‚ which is of high efficiency. Currently‚ aggregate crushing plant requirements in ghanathere are two ways of sand making: wet type sand making technology and dry type sand making technology. So‚ which one can be selected according to individual circumstance? At first

Brazil was first visited by the Portuguese they quickly found that there were rich lands and money to be made off those lands. The coastal areas of Brazil were taken by wealthy settlers‚ this was over 500 years ago. Jorge Amado’s “Captains of the Sands” was written in 1937 and although the main theme was set around a group of orphan children who ran the streets‚ there were political undertones that also told a story of the divide between the rich and the poor. When the Portuguese first arrived there

1. Two ships P and Q are moving along straight lines with constant velocities. Initially P is at a point O and the position vector of Q relative to O is (6i + 12j) km‚ where i and j are unit vectors directed due east and due north respectively. The ship P is moving with velocity 10j km h–1 and Q is moving with velocity (−8i + 6j) km h−1. At time t hours the position vectors of P and Q relative to O are p km and q km respectively.
