Does high spin damage clothes? Myth: Higher spin speeds will ruin your clothes! Busted: No! Higher spin speeds will not ruin your clothes when you use the appropriate settings. High spin speeds are ideal for cottons, bulky items such as towels and bedding and denim. How long should you spin your clothes? A normal drying […]
What are two substances?
What are two substances? Two Main Types of Pure Substances Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it. […]

Why we should not ban smoking?
Why we should not ban smoking? Scientists agree that smoking is dangerous. Tobacco smoke can cause cancer, strokes and heart disease. Smoking does not just harm the smoker – it also harms people nearby, who breathe in the smoke (this is called “passive smoking”). Smokers choose to smoke, but people nearby do not choose to […]
Can you diffract a human?
Can you diffract a human? Since Plank’s constant is on the order of 10-34, the de Broglie wavelength is virtually undetectable for large amounts of matter. There is much evidence of matter possessing such a de Broglie wavelength. Well, theoretically, since all matter possess wave-like properties, so do humans, and cats, and whatever you please. […]
Can you use the quadratic formula for inequalities?
Can you use the quadratic formula for inequalities? In other words, a quadratic inequality is in standard form when the inequality is set to 0. Just like in a quadratic equation, the degree of the polynomial expression is two. This method of solving quadratic inequalities only works if the quadratic factors. What is the purpose […]
Why do pennies sink in water?
Why do pennies sink in water? The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float. What […]
How high will it bounce rebound ratios?
How high will it bounce rebound ratios? Tennis balls: Must rebound approximately 111cm when dropped from 200 cm. Soccer balls: Must rebound approximately 120cm when dropped form 200cm onto a steel plate. Basketballs: Must rebound approximately 53.5 inches when dropped from 72 inches onto a wooden floor. How can you tell how high a ball […]
What planet spins the fastest?
What planet spins the fastest? Jupiter What determines how fast a planet spins? The rotational speed is normally determined by the initial angular momentum when the planet formed, but may also be altered subsequently by large collisions (as for example the collision of the earth with another planet which gave us our moon). Why Jupiter […]
Is earthquake epicenter randomly distributed on Earth?
Is earthquake epicenter randomly distributed on Earth? Earthquake epicentres are not randomly distributed on earth. They occur wherever two tectonic plates meet. The collision of these plates leads to the occurrence of earthquakes and volcanoes. About 75% of world’s largest volcanoes and 90% of earthquakes occur along the Pacific Ring of Fire. How do you […]
