When reading the definitions of work the first few examples seem to focus on what is the most widely recognized form of the word. Referring to one’s employment. When we hear people use the word ‘work’ it is usually spoken of going to or coming home from. Education and experience …

Use the postulates of the kinetic theory to explain the following: i)Matter can exist in three states ii)The pressure exerted by a confined gas decreases as its temperature is lowered iii)A gas of low molecular mass will diffuse through air faster than a gas of high molecular masseven though both …

Questions 1. What is the relationship between the angle of incidence and the angle of refraction? The angle of incidence (formed by the ray of light travelling though air into a slab of rectangular perspex) is not directly proportional to the angle of refraction (angle formed between the ray travelling …

Q1 – As the pulse travels down through the spring, its, size and amplitude is reduced – the sizes of the waves are much smaller as the forces become weaker (losing energy) as the distance from the point of initiation is increased. Q2 – Pulses do not ‘catch up’ with …

Aim: a:, To observe changes in motion due to changes in force and measure force, mass and acceleration, and examine their influence on motion. b: To investigate the relationship between the variables; mass, force and acceleration and determine an inertial mass through the use of a trolley, ticker-timer and set …

I believe that the school should have a one-year physical education course in our school for all the students because it can be beneficial. Having a physical education course can help the student maintain in shape and strength. Some indoor activities for the students that I think they should do …

Structure of the atom · An atom is the smallest part of an element that can be part of a chemical reaction – in other words, an atom is the smallest particle that can exist naturally · When two or more atoms join up they form a molecule. Atoms are …

PROBLEM Investigate the heat energy in a range of alcohol’s used as fuels. HYPOTHESIS I predict that octanol will release the most heat energy. This is because there is more bond energy in that molecule than the other alcohols. Within a molecule there are bond energies that are holding the …

The play is set in a fictional town in Indiana called Jackson. It is centered on a girl’s life from age five to age twenty-six named Elisabeth. This girl has a disability called cerebral palsy and is unable to move her legs, so she is confined to a wheelchair. The …

Photosynthesis is a food making process for algae and plants. The photosynthesis process rate varies from different wavelengths and intensities of light. This lab will evaluate the optimal wavelengths and degrees of intensity during photosynthesis when chloroplast is exposed to light. The mixtures of DCPIP with water, PO4 buffer, and …
