Who created the boogaloo dance? Use of the term boogaloo in referring to a musical style was probably coined in about 1966 by Richie Ray and Bobby Cruz. The biggest boogaloo hit of the ’60s was “Bang Bang” by the Joe Cuba Sextet, which sold over one million copies in 1966. “El Pito” was another […]

How can we predict a change in motion? Newton’s second law of motion says that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. You can use it to predict the motion of an object. The net force is the vector sum of […]

Why are blue holes so dangerous? So, why is the Great Blue Hole so dangerous? The Great Blue Hole of Belize is dangerous for three reasons: the inexperienced divers, water clarity, and the presence of sharks. Those three elements can alter the mindset of the divers and push them to make bad decisions while scuba […]

What is the name of James Chadwick atomic model? This atomic model is known as the quantum mechanical model of the atom. In 1932, James Chadwick bombarded beryllium atoms with alpha particles. An unknown radiation was produced. Chadwick interpreted this radiation as being composed of particles with a neutral electrical charge and the approximate mass […]

How can I cheat in cricket? Walking or standing your ground, mired in all this discussion is another trick a batsman can use. If you do have a reputation for walking and are playing a big game, you can nick off but stand your ground. The umpire can be fooled into thinking you would have […]

Why are they called alkali metals? Why are they called the alkali metals? The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide. Alkalies react with acids to form salts. What are 3 facts about alkali […]

What part of body regulates body temperature? Our internal body temperature is regulated by a part of our brain called the hypothalamus. The hypothalamus checks our current temperature and compares it with the normal temperature of about 37°C. If our temperature is too low, the hypothalamus makes sure that the body generates and maintains heat. […]

Do you water plants when they are dormant? Dormant plants need less frequent watering than those in active growth. After plants begin to grow new leaves, watering once every 7 to 10 days is adequate until the weather warms and the plant begins active growth. Then water as needed. Can a dead plant come back […]

What is a persons carbon footprint? A carbon footprint is the total amount of greenhouse gases (including carbon dioxide and methane) that are generated by our actions. The average carbon footprint for a person in the United States is 16 tons, one of the highest rates in the world. Why is it important to reduce […]

What 2 things could you do to decrease density? Density can vary according to temperature and pressure. Applying pressure to an object decreases volume, which then increases density. Increasing the temperature of an object almost always decreases its density by increasing its volume. Is oil less dense than water? Show the Animation Density of Liquids. […]
