Module 2

Healthy eating

  • Read the passage about Robinson Crusoe again.

Healthy eating

  • Why were the children so pleased to find the fruit?
  • Why was it so important for Robinson Crusoe to find fresh fruit? After all, he had the food which he had found on the ship.
  • Do you think the water was clean?
  • Where will he get pure/clean water?
  • What can he do to purify the water?
  • Many years ago ships could not carry much fresh food as it would all go bad. There were no fridges to keep it fresh. Sailors mostly ate dried food and food which would keep.

But our bodies need the vitamins, which we get from fresh fruit and vegetables. Sailors on long voyages would often get scurvy from a lack of vitamin C. This caused their teeth to feel loose in their gums and could even fall out.

This is one of the main reasons why the Europeans came to South Africa. They wanted a place to stop and get fresh food when on their long voyages to the eastern countries like India and China.

Think of your favourite fruit and vegetable. Draw it here and find out how it helps your body.

The first thing Robinson wanted to do when he was shipwrecked was to find food and water. We cannot live without it. Our bodies cannot work without the energy that they get from food.

One of the most important things that we need for our bodies to grow is protein. We find this in most products that come from animals.

List, draw or find pictures of some of the food we get from animals.

milk; eggs; chops; butter; cream

But we don’t only need protein. Our bodies need the important vitamins found in fruit and vegetables. Vitamins help our bodies in different ways.

Vitamin A is found in carrots, broccoli, squash and spinach . It helps our skin, bones and teeth to grow well.

Carbohydrates and sugar give us energy. But too much of these can make you fat!

Some people don’t eat meat at all. They are called vegetarians. How will their bodies grow properly if they don’t eat proteins?

Proteins can also be found in nuts and soya products.

People have different reasons for not eating meat.

  • Try to think of some.

One of the main reasons has to do with religion. Many religions set out rules for following a healthy diet.

Just as you need to keep God’s rules to live a good life, you need to eat the right food to keep your body healthy.

Muslims, for example, make sure that their food has been prepared according to the rules of their religion and they call this food Halaal.

The Jewish people do the same. If their food is prepared properly, it is called Kosher. The Jewish faith also forbids people to eat the meat from a pig and the Hindu people will not eat the meat from a cow. This is because the cow is regarded as a sacred animal.

Although there are many different beliefs, most people believe that Life is precious. They give thanks that they are alive and have healthy bodies. They do what they can to stay healthy and respect their bodies.

Find out what your own religion feels about the way you should look after your body. What do you think?

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 the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

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?
Robert
like charges repel while unlike charges atttact

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).
