    Investigating Air Resistance We are trying to investigate the effect of air resistance to the speed of a trolley moving down a ramp in relation to the area of a sail attached to the trolley. The prediction I have made is that the larger the sail area, the longer the trolley will take to descend, i.e. it will be slower. The variable I will be changing is the height of the sail, and so, the area of the sail. Some variables cannot be changed, but may affect the result of the experiment

    Air Resistance on a Fan Car Problem: When a large fan is blowing air against the fan car at three different speeds (high, medium, and low), then will the overall speed be lowered? Materials: · Fan car (K’NEX pieces, small, battery-powered fan, wheels with tires) · AA batteries · Large 3-speed fan · Timer · Masking tape Process: 1. Load two AA batteries into the fan that is attached to the K’NEX car. 2. Mark a starting line and a finish line two meters away from each other with

    narrow. This is so a minimum of air resistance or drag affects the dragster with lower drag better acceleration an in turn a better top speed can be achieved all leading to a better pass (race time). Now lets try to understand the concept of air resistance and drag. A basic example is placing your hand out the window with your palm facing forwards as you are driving your car along at about sixty kilometres per hour. You will feel a strong force of the wind (air resistance) pushing back at your hand.

  • Antibiotics Essay

    . Many doctors and patients are unaware that antibiotics are designed to treat bacterial infections, not viral infections (Antibiotic resistance, N.D.). Many bacteria within our bodies are not harmful at all, and some of them actually provide health benefits. The bacteria that are harmful are disease-causing bacteria, which generate sicknesses such as strep throat, the common cold, and ear infections (Get, 2013). Viruses are smaller than bacteria and require hosts, such as plants or animals, in order

    Drug Resistance Rising Among Mycobacterium tuberculosis Cases Abstract Drug resistance has been increasing among patients infected with Mycobacterium tuberculosis. Previous miracle drugs that were used in the 1950s have now been proven useless in many cases simply because the bacteria are not susceptible to antibiotics such as isoniazid, rifampin, pyrazinamide, etc. when they are taken. This pathogen is easily transmitted through air and has the capability of attacking the respiratory system

    his ill-gotten gains. The Danish resisters took the offensive against German occupying forces.
