You must be too far from the Earth to feel the force between you and the Earth. Right now I'm ~6400 km from the center of the Earth; you must be much farther away.
A2 You can't feel the gravitational force that a mountain or a building attracts you because the force is too small. The force is proportional to your mass times the other mass and only the earth has a large enough mass for this force to be felt, which is your weight. Gravity is considered the weakest of the fundamental forces.
Bad things. When your blood is circulating too hot, it affects everything. Your internal organs are stressed, as well as your brain. (which is why it's dangerous to have a high fever for very long) Your muscles start burning anything they can to function instead of oxygen, which results in them producing lactic acid. (that's why after you exercise you feel that burn) The body uses up all the liquids it can, taking them from needed functions. It's a dangerous state to be in--for short.
Some of the bad things are: dizzyness,headache.hurts to do anything,and you don't even want to open your eyes. If you do overheat just sit or lie down until you feel better. when you do get up you will feel a little dizzy still but don't worry that's normal.
the climate in Ghana is very hot
very very very hot over 123 Fahrenheit
It could be a "CV" joint, wheel bearing, ball joint, strut or any of a number of loose parts. It depends on the type of knocking and how it sounds. In any case, it should be repaired as soon as possible to avoid the possibility of a dangerous condition.
Coca-Cola and the Rusty Nail
Mostly it's the carbonic acid. Carbonic acid is created when Carbon Dioxide is dissolved in water. It's a normal process and carbon dioxide naturally occurs in rainwater, although in a very weak solution. Carbon dioxide under pressure will create a stronger carbonic acid, giving the characteristic bubbles that we detect in "soda" drinks. Carbonic acid is responsible for dissolving minerals which end up in caves as stalactites and other cave features. If you think about it, the same acid that dissolves calcified rock and makes the cave formations will certainly act on iron. Many people try to frighten people by rusting a nail in Coke. You can also rust a nail in an orange, a grapefruit or a pineapple, but don't take my word for it. Some soft drinks also include Phosphoric acid, which adds a tartness. The phosphoric acid is not nearly as strong as the carbonic acid in your Cola, Doctor Pepper or other soft drink, but it too will contribute slightly to the reaction.
BTW, it is recommended that you not consume more than 1 or 2 drinks per week that contain phosphoric acid.
