The Scientific Revolution was a big change throughout Europe; it changed the medieval views of the world. It started with medieval views as the framework‚ The Renaissance stimulating science‚ navigational problems needing new instruments‚ and scientific methodology. This seemed to be a big impact on the world. Religiously‚ this challenged some views from the Bible. In Philosophy‚ It started a new way of thinking‚ thus shows both were impacted by the Scientific Revolution. Religious: .Nicolaus

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

direct paths to radar inside the forest. The human is modeled using PEC ellipsoids‚ created based on the Boulic model as described in Section 2. The forest is modeled using identical trunks of 3 meters height and 11 cm radius which are distributed uniformly inside the 40£40m2 region. PEC is assumed for the trunk material properties as well as the ground. A trunk density of 3.8% (#/m2) is assumed‚ which amounts to 35 trunks within the half power beamwidth of the antenna‚ with average closest neighbor
