Purpose: To find out the densities and to find out the name of the unknown metals. (Based on the extensive and intensive properties) Check up the words mass‚ volume‚ density‚ extensive properties‚ and intensive properties. Where do the units for mass and volume) come from and what do they mean? What is the density of distilled water? What is Archimedes principle? Does temperature affect the density of a solid? Liquid? Gas? Materials: Safety glasses‚ 10‚ 25 or 50 mL graduated cylinders

’Spring’ ’How does Hopkins use language and style to convey his message to his readers?’ Gerard Manley Hopkins was a 19th-century poet whose poetry work mainly consisted of religion‚ nature and inner anguish as the main themes. Hopkins celebrated beauty in the nature world and he loved the season of spring‚ especially the freshness it brought. In most of his poems‚ like ’Spring’‚ Hopkins linked in nature to prayer and religion; he thought that the pure beauty in nature alone‚ was enough

Most of performers have great instrument skill and show us a wonderful music. Each movement highlights the character‚ range‚ and technical abilities of an individual instrument‚ all of pieces stand on their own as intricate musical gems. The show was divided for two parts‚ and they have different

on one side and glass on the other were used. All of the blocks had a soup can with a mass of 0.41 kg placed on top in order to provide enough mass to allow readings to be taken. They were moved along a wood plank while being attached to a 500-g spring scale in order to record the values when a) the block first moved‚ representing μs and b) as it traveled at a constant speed‚ representing μk. In one experiment the wood block was placed on its side and the experiment repeated. Overall‚ the results

The spring constant Manuel Cereijido Fernández – UO237242 PL-4 -----------------------------------------------------------------------------------1. Objectives The main objective of this experiment was to determine the spring constant using the dynamic method. 2. Theoretical fundamentals On the one hand‚ when a spring oscillates‚ the movement which describes can be classify as a simple harmonic motion. Therefore‚ its position‚ velocity and acceleration equations respect the time will
