Commentary on Soliloquy 1 – Shakespeare’s “Hamlet” In Shakespeare’s “Hamlet”‚ the first soliloquy spoken by the protagonist reflects the feelings of unrest plaguing this character and successfully sets up the religious framework for the remainder of the play. A soliloquy is spoken by a character that is alone on stage‚ and reveals the speaker’s thoughts and feelings towards particular events. The effect of the soliloquy is that the audience is given insight into these thoughts‚ which in turn aid

DP Physics IA Thermal physics: Specific Heat Capacity of Metals Introduction: In this experiment we are going to measure the specific heat capacity of a unknown metal. To measure the specific heat capacity we will heat up the metal to certain temperature and release the metal in beaker filled with water. By knowing the mass and temperature of water filled in beaker‚ we will be able to calculate the specific capacity of unknown metal by change in temperature of beaker willed
