Transport

1. Improved means of transport

In the years before factories started to mass produce goods in large quantities, people worked on a smaller scale, either at home or in smaller buildings. They used to walk to work and therefore lived as close to work as possible . Towards the middle of the 19th century (about 1825 – 1875) the industrial revolution took place; machines were manufactured, the first motor cars were assembled and factories were erected. Means of transport were developed, and soon it would not only be cars, but also trams, steam trains and eventually electric trains, tube trains, buses and fast cars. People could suddenly live further away from the workplace , which meant that the boundaries of towns and cities were expanding rapidly. This had a big influence on the inside and outside appearance of the city, e.g.

The workplace and living areas gradually became further removed from each other;

various types of living areas (upper class, middle class and working class) and working areas (office blocks and shops in the centre of town; factories on the outskirts of town) sprang up;

tall buildings were erected in city centres or the centre of towns, because this was where everyone wanted to be; land became more expensive and people started building “on top of other buildings” (storeys); a new method of transportation, the elevator, came into use;

roads and railway lines were constructed and people erected their homes and businesses alongside so that towns and cities began to take on different shapes if viewed from the top.

large areas of towns/cities have tarred surfaces for parking, streets were widened and concrete jungles developed;

many of the functions in the centre of town (CBD - Central Business District), such as cinemas, bigger shops, offices, etc. have relocated to the suburbs. Large shopping centre complexes, such as Tyger Valley Centre and Eastgate were built and accommodate a large number of functions under one roof. One stop shopping conveniences with ample parking areas and less traffic draw large numbers of people every day.

the city suddenly started expanding in almost all directions, making it difficult to say what shape a city is taking on. Most cities have no particular shape.

2. What impact does this development have on the people in our country?

We already know that cities are enormously popular and that literally thousands of new residents move to bigger towns and cities, some because they have been transferred and already have work, and others in the hope of getting a job to earn a better living. Let’s try to form an image of the effects of the huge expansion of towns and cities:

People move to city surroundings for various reasons. It is estimated that between 10 000 and 15 000 new residents move into the larger Cape Town area every month. Some of them (a small group) have jobs, have been transferred or feel like a change of surroundings and are usually financially sound. Most of them, however, hope to find work and make a better living. We start by focussing on this group;

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone
definitely of physics

how do lnternal energy measures

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
