Is it normal for microwave to get hot? It is normal to feel a warm outer case on the control panel side. The heat is normal and comes from the power transformer. Further, cooking foods in a microwave oven for an extended period of time can cause a heat transfer not only to the internal […]
What are disadvantages of Google?

Apps only limited to Google apps only. The site URL must begin with “sites.google.com/site/” which is to long for a website. How Google is useful for students? Google […]
What is the group number are these metals reactive?
What is the group number are these metals reactive? The alkali metals, found in group 1 of the periodic table (formerly known as group IA), are very reactive metals that do not occur freely in nature. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron […]
What is the minimum size required for a communication system grounding electrode conductor?
What is the minimum size required for a communication system grounding electrode conductor? 14 AWG Why is the earth not considered an effective ground fault current path? The earth is not considered as an effective ground- fault current path. The resistance of earth is so high that very little fault current returns to the electrical […]
How a capacitor stores charge in an electric field?
How a capacitor stores charge in an electric field? If you have a positive electrical charge and a negative electrical charge, they attract one another like the opposite poles of two magnets—or like your body and Earth. Its two plates hold opposite charges and the separation between them creates an electric field. That’s why a […]
Can energy leave a system?
Can energy leave a system? First Law of Thermodynamics: Energy can be changed from one form to another, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant, merely changing from one form to another. Is work out positive or negative? The first law is simply […]
What are characteristics of groundwater?
What are characteristics of groundwater? Some of the most typical characteristics of groundwater are weak turbidity, a constant temperature and chemical composition and almost overall absence of oxygen. Circulating groundwater can have extreme variation in the composition with the appearance of pollutants and various contaminants. What is an example of groundwater? Groundwater originates from rain […]
How does force affect swimming?
How does force affect swimming? The effect of buoyancy in swimming is best described by Archimedes’ principle: a body fully or partially submerged in a fluid is buoyed up by a force equal to the weight of the fluid that is displaced by the body. This effectively negates any effects that gravity might have on […]
Is ethanol solution a dependent variable?
Is ethanol solution a dependent variable? Variables: Independent variable: Reagents (ethanol, Na, concentrated ethanoic (acetic) acid, concentrated sulphuric acid, 2-hydroxybenzoic acid, pentanol, dilute sulphuric acid, potassium dichromate(VI) solution, propan-2-ol) Dependent variable: The qualitative changes in the substance (smell, colour, percipitate etc.) What factors could affect Daphnia heart rate? Daphnia is poikilothermic, which means that its […]
What is the evidence of nebular theory?
What is the evidence of nebular theory? What Evidence do we have of a Nebular Theory-type development? We have observed discs of gas and dust around other stars. We can also see evidence of stars and planets forming in clouds of gas and dust; young planet systems in the making are called Proplyds. What is […]
