Can atoms be broken down into smaller pieces? Under normal circumstances an atom can be broken down into any smaller particles, but we humans, have devised ways to break the atom apart. An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. How many atoms are […]

Is it OK to sleep with plants in your bedroom?
Is it OK to sleep with plants in your bedroom? While many plants release carbon dioxide, not oxygen, at night, having a few plants in the bedroom will not release enough carbon dioxide to be harmful at all. Also, not all plants release carbon dioxide at night. With proper plant selection, growing houseplants in bedrooms […]
What does the placenta sound like on a Doppler?
What does the placenta sound like on a Doppler? Whenever you use a doppler, you’ll hear a variety of sounds depending on where it’s placed. A “whooshing” sound usually indicates either placenta or movement. Some people also describe the noise as similar to that of blowing trees. This should not be mistaken for a baby’s […]
What kind of a wave is sound?
What kind of a wave is sound? These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave. How ECHO is created? An echo is made by sound […]
What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
What is the difference between absorption and reflection?
What is the difference between absorption and reflection? Reflection means that they are thrown back from a surface; absorption means that they are incorporated by a surface and transformed into heat energy. Different surfaces reflect and absorb differently. The ratio between absorption and reflection is called albedo. What is P in Beer’s law? Absorption takes […]
Is 1 degree Celsius cold or hot?
Is 1 degree Celsius cold or hot? In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water compared to 180 degrees in the Fahrenheit scale. This means that 1 °C = 1.8 °F (check the section about temperature differences below). What is the coldest Fahrenheit temperature? The […]
What is the homogeneous product?
What is the homogeneous product? A homogeneous product is one that cannot be distinguished from competing products from different suppliers. In other words, the product has essentially the same physical characteristics and quality as similar products from other suppliers. One product can easily be substituted for the other. What is homogeneous and differentiated products? 1. […]
Does aluminum or lead have a greater buoyant force?
Does aluminum or lead have a greater buoyant force? Insight: Although each sphere experiences the same buoyant force, the lead sphere is more massive than the aluminum sphere and therefore the lead sphere still weighs more while submerged than does the aluminum sphere. Is lead buoyant? The specific gravity of lead is 11.34 – which […]
