Aim: To determine a value for the spring’s force constant‚ k. Introduction: Hooke’s Law indicates the relationship between the amount of extension‚ e‚ of a spring to the size of the force‚ F‚ acing on it. This relationship may be written as :- F = ke F = ke where k is a constant for which particular spring you are using. It is the force constant of the spring. * The force applying on the spring‚ F‚ is denoted by Newton in SI Units. (N) * The amount of extension of the spring

Lab 4 – The Cell Answer Key Procedure 4.3 Draw a picture of a single Elodea cell and label all visible structures. See the diagram in your lab manual. Without staining‚ the only structures that should have been clearly visible should have been the cell walls and the green chloroplasts. Is this cell prokaryotic or eukaryotic? ______Eukaryotic_______________________ What evidence do you have to support this claim? The presence of organelles (chloroplasts) and its large size.

Introduction of Physics: Physics ("knowledge of nature") is the science concerned with the discovery and understanding of the most basic fundamental laws of the universe that control the way everything in the world around us behaves. Discoveries in basic physics have important ramifications for all of science. Physics attempts to describe the natural world by the application of logic scientific methods‚ including modeling by theoreticians. As a core scientific discipline‚ physics is concerned with
