Physics HSC Notes Space 1. Earth has a gravitational field that exerts a force on objects both on it and around it. K1 Define weight as the force on an object due to a gravitational field. Mass is the amount of matter within an object‚ measured in kg Weight is the force of gravity acting on an object’s mass measured in newtons (N). Weight is a force thus a vector quantity. K2 Explain that a change in gravitational potential

Now the big question is‚ should we spend it or save it? The major advantage of saving money is being

File Storage and Retrieval Information stored in a mass storage system is conceptually grouped into large units called files. A typical file may consist of a complete text document‚ a photograph‚ a program‚ a music recording‚ or a collection of data about the employees in a company. Mass storage devices dictate that these files be stored and retrieved in smaller‚ multiple byte units. For example‚ a file stored on a magnetic disk must be manipulated by sectors‚ each of which is a fixed predetermined

GDP Per Capita as a Measure of well being When countries are compared using their GDP per capita important factors such as health‚ education and quality of environment are not included and thus the overall well being of the nation may not be accurately measured‚ in order to determine whether this statement is accurate we should compare well being in countries with differing GDP per capita results‚ we will examine various statistics from the United States‚ Norway and the Netherlands. Factors such

10 Mary Street by Peter Skrzynecki demonstrates the importance of place to our identities through the childhood memories of Skrzynecki‚ who displays a sense of cultural alienation due to his Polish heritage. Their home on 10 Mary Street is a small space of security in an otherwise foreign land. This familiarity is evoked through vivid garden imagery‚ and we can picture “rows of sweet corn; Tended roses and camellias” which his parents care for “like adopted children”. The simile emphasises the parent’s

DIFFERENT STORAGE TECHNIQUES FOR FRUITS AND VEGETABLE Food spoilage: Every change in food that causes it to lose its desired quality and eventually become inedible is called food spoilage or rotting. Factors affecting storage life The natural limits to the post-harvest life of all types of fresh produce are severely affected by other biological and environmental conditions: Temperature: An increase in temperature causes an increase in the rate of natural breakdown of all produce as food reserves

Space technology has been developing considerably these recent decades. New discoveries about the moon and others planets are fascinating us. Even some fiction movies make us think that one day we can go to live on another planet. However‚ for the following reasons I do not support the idea that government should spend as much money as possible on developing space technology for the exploration of the moon and others planets. Space technology is very expensive and needs a colossal investment

visible rays. Example: Fluorescent mercury-vapour lamp. High pressure mercury vapour lamp: It consists of a discharge envelope enclosed in an outer bulb of ordinary glass. The discharge envelope may be of hard glass or quartz. The space between the bulb is partially or completely evacuated to prevent heat loss by convection from the inner bulb. The outer bulb absorbs harmful ultra rays. The inner bulb contains argon and a certain quantity of mercury. In addition to two main electrodes
