Which coin held more water droplets and why? Observations and results You should find that plain tap water produces a much larger, stable drop of water on top of the penny than the soapy water does. This is because plain tap water has higher surface tension, so the surface is “stronger” and can hold together […]
What is the general formula of ketone?
What is the general formula of ketone? The simplest ketone is CH₃—C(=O)—CH₃. Its molecular formula is C₃H₆O. From this formula we can say that for “n” carbon atoms we need “2n” hydrogen atoms and an oxygen atom. Hence general formula of ketone is CnH₂nO. Which of the following is an example of aldehyde? Aldehydes are […]
How do you calculate the force exerted on a charge?
How do amino acids react to form polymers?
How do amino acids react to form polymers? 1 Amino acids undergo condensation to form a molecule called a dipeptide. The C−N bond is called a peptide bond. These can react with additional amino acids to lengthen the peptide. The process can continue until thousands of units have joined, resulting in large proteins. What do […]
What three things are used to make glucose in photosynthesis?
What three things are used to make glucose in photosynthesis? Rather, plants use sunlight, water, and the gases in the air to make glucose, which is a form of sugar that plants need to survive. This process is called photosynthesis and is performed by all plants, algae, and even some microorganisms. Where do plants store […]
What are the advantages and disadvantages of using biomass?
What are the advantages and disadvantages of using biomass? Biomass Advantages and Disadvantages Biomass is always and widely available as a renewable source of energy. It is carbon neutral. It reduces the overreliance of fossil fuels. Is less expensive than fossil fuels. Biomass production adds a revenue source for manufacturers. Less garbage in landfills. Biomass […]
What do subscripts represent in math?
What do subscripts represent in math? Subscripts are those little numbers in the bottom right Sometimes equations may have variables with subscripts (tiny numbers just after the variable). This is especially the case in science subjects such as chemistry or physics. Well, the variables in science often represent something specific. What is subscript example? Subscript […]
Why are glaciers so dirty?
Why are glaciers so dirty? Ice cliffs, a unique feature of debris-covered glaciers, “are normally very dark and dirty and absorb a lot of solar radiation,” Pellicciotti says. More crucially, the ice cliffs also soak up heat emitted by hot rocks around them, she says. Water is darker and absorbs more solar radiation than the […]
What are the 4 main types of waves?
What are the 4 main types of waves? Types of Waves in Physics Mechanical waves. Electromagnetic waves. Matter waves. Why does each wave look differently? Answer: The waves look different because it depends on how fast you move the rope. When you move the rope slowly, bigger but fewer waves will be formed. While when […]
Why charge resides on the surface of conductor?
Why charge resides on the surface of conductor? If there is an electric field inside the conductor then an electric force which will accelerate the charges inside which is not observed. The charges reside on the surface in a manner so as the system stays in equilibrium. Can charge reside on the inner surface of […]
