AMOUNT

Because the post office was the only place in the town that still had electricity it served as a base for rescue workers. As Mr Hougaard received telephonic information about inhabitants severely affected by the earthquake, rescuers were sent out.“The lines were overloaded because everyone was phoning to hear what had happened and where they should go.”Shortly after this Mr Hougaard went to have a look at his own house, which he had just bought. Although he can’t remember the exact amount, the damage caused to his house cost more to repair than he paid for the house originally.His wife, who was expecting their second child, was cut on the head when a badminton trophy fell from the pelmet onto her head. For months after this she refused to sleep inside at night.Mr NC Krone, owner of Twee Jonge Gezellen and vice-chairman of the Boland Disaster Committee said that most inhabitants of Tulbagh were badly affected, yet the spirit of co-operation was a wonderful memory. “Emergency aid streamed into the disaster-struck towns and a comprehensive disaster relief programme was instituted on the night of the earthquake by the Defence Force with the assistance of the Police and local authorities.”The next day 400 tents were erected in Tulbagh, 250 in Wolseley, and 100 in Ceres. The Army erected a field hospital in Wolseley. Two days later the water shortage was relieved and new pipes were laid to the mountains to replace pipes damaged by falling rocks.

DONATIONS

Nearly all of the R13 million controlled by the Disaster Committee was spent. Almost R1.3 million was raised from public donations.

VOLCANOES

  • If the pressure under the mantle builds up the magma is forced through weak places and cracks in the crust. These weak places form volcanic pipes. When the magma reaches the surface of the earth it forms solid rock. This rock blocks the volcanic pipe and the pressure from below builds up. Eventually the pressure is sufficient to cause a huge explosion. The solid rock (the plug) is blown away and the magma erupts from the pipe. A volcanic explosion like this can sometimes destroy a whole town.
  • There are fewer than 500 active volcanoes on Earth. An active volcano is one that erupts from time to time. More than half of these volcanoes are in an area around the Pacific Ocean.

Assessment

Learning Outcome 2: The learner will know and be able to interpret and apply scientific, technological and environmental knowledge.

Assessment Standard 2.1: We know this when the learner categorises information: compares features of different categories of objects, organisms and events;

Assessment Standard 2.3: We know this when the learner interprets information: interprets information by identifying key ideas in text, finding patterns in recorded data, and making inferences from information in various forms (e.g. pictures, diagrams, text).

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?
ninjadapaul

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
