Why are pendulums not SHM? Any pendulum undergoes simple harmonic motion when the amplitude of oscillation is small. The pendulum still oscillates, but the motion is no longer simple harmonic motion because the angular acceleration is not proportional to the negative of the angular displacement. What is the maximum displacement of a body in simple […]
How much energy is needed to completely melt a 15 g of ice?
What is the biggest fish in the St Lawrence River?
What is the biggest fish in the St Lawrence River? walleye Can you drink St Lawrence river water? The River is 250 feet at its deepest point. Flowing through both Canadian and US lands, the St. Lawrence River is a bi-national waterway, providing drinking water to local municipalities on both sides of the River and […]
Do solar powered calculators last forever?
Do solar powered calculators last forever? How Long Do Solar-Powered Calculators Last? The purpose of creating solar-powered calculators was to make them long-lasting, so in general, they have a very long lifetime. How do calculators never die? Calculators use very little power, so it’s battery lasts many years. Some calculators have a small solar panel […]
What is the most sensitive type of spectroscopy?
What is the most sensitive type of spectroscopy? Among instrumental techniques, fluorescence spectroscopy is recognized as one of the more sensitive. In fluorescence, the intensity of the emission of the sample is measured. The reason for the high sensitivity of fluorescence techniques is that the emission signal is measured above a low background level. What […]
Is powdered chocolate a solute?
Is powdered chocolate a solute? The solution of hot chocolate becomes one mixture rather than powder and water. The substance that is being dissolved in another substance is called the solute. In this example, the hot chocolate powder is the solute. Is chocolate powder dissolve in hot water easily? Explanation: Hot water has more energy […]
Can transmission electron microscopes see DNA?
Can transmission electron microscopes see DNA? High-resolution transmission electron microscopy is combined with a novel preparation method, based on superhydrophobic sample control, to achieve a spatial resolution of down to 1.5Å. What are the advantages of transmission electron microscope? TEMs offer the most powerful magnification, potentially over one million times or more. TEMs have a […]
Are oil stains permanent?
Are oil stains permanent? The problem with oil stains is that instead of leaving a brightly stained area, they tend to leave a slightly darkened area that may be difficult to notice right away. This area darkens with age unless it is removed quickly. And if the piece of clothing and oil stain dry, the […]
Where is kinetic energy the greatest on a hill?
Can crystals grow?
Can crystals grow? Scientists typically describe crystals as “growing,” even though they are not alive. Each crystal starts small and grows as more atoms are added. Many grow from water rich in dissolved minerals, but they also grow from melted rock and even vapor. What are three ways crystals form? You can grow crystals in […]
