Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this

Amplitude - the height of a wave from the origin to a crest‚ or from the origin to a trough. Atomic emission spectrum – a set of frequencies of electromagnetic waves given off by atoms of an element; consists of a series of fine lines of individual colors. Electromagnetic radiation – a form of energy exhibiting wavelike behavior as it travels through space; can be described by wavelength‚ frequency‚ amplitude‚ and speed. Electromagnetic spectrum – includes all forms of electromagnetic radiation;

Colligative Properties The Physical Properties of Solutions Colligative Properties • There are 3 colligative or physical properties of solutions that you should know. They are Vapor pressure Boiling point elevation Freezing point depression Osmotic pressure is one you don’t need to worry about. 1. 2. 3. 4. Molality • Molality measures the moles of solute dissolved in the mass (kg) of solvent. • Molality normally expresses concentrations of colloids. • m = moles solute kg solvent

What Einstein Told His Barber Summaries Chapter 3 Summary Heat if a form of energy that all other forms of energy primarily evolve around. Whenever one form of energy transforms from one to another some of this energy is lost or gained in the form of heat. Restoring lost heat molecules and atoms needs energy so in the end you lose instead of gaining energy. Heat travels from areas of high temperature to areas of lower temperatures. Confusion of temperature and heat is a common. Heat is energy

Thinking back in time I found the poem “ This Moment” by Eavan Boland a complicated poem when I read it for the first time. I started to question myself once I finish reading it‚ what does this poem wants to tell us? The sentence was very short and each stanza doesn’t seem to be very related to each other. However‚ once I read it for the 2nd and 3rd time‚ I came to realize that the speaker wants to describe about a specific moment in her life. Starting from the daily life and activities she did
