What is the direction of the electric field in the rod? The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. Since electric field is a vector quantity, it can be represented by a […]
What are the factors affecting the solubility?
What are the factors affecting the solubility? Solubility is the maximum amount of a substance that will dissolve in a given amount of solvent at a specific temperature. There are two direct factors that affect solubility: temperature and pressure. Temperature affects the solubility of both solids and gases, but pressure only affects the solubility of […]
What will make an object move in a circular path?
What will make an object move in a circular path? A centripetal force is a net force that acts on an object to keep it moving along a circular path. The tension force in the string of a swinging tethered ball and the gravitational force keeping a satellite in orbit are both examples of centripetal […]

Which WiFi frequency is best?
Which WiFi frequency is best? Ideally, you should use the 2.4GHz band to connect devices for low bandwidth activities like browsing the Internet. On the other hand, 5GHz is the best suited for high-bandwidth devices or activities like gaming and streaming HDTV. What is the advantage of having WiFi in your car? Benefits of car […]
What is DNA as genetic material?
What is DNA as genetic material? DNA, deoxyribonucleic acid, is the genetic material in your cells. It was passed on to you from your parents and determines your characteristics. Where is genetic material found? The genetic material of a cell or an organism refers to those materials found in the nucleus, mitochondria and cytoplasm, which […]
What are the major causes of freshwater pollution?
What are the major causes of freshwater pollution? Pollution may be caused by fecal waste, chemicals, pesticides, petroleum, sediment, or even heated discharges. Polluted rivers and lakes are unfit for swimming or fishing; polluted water is unsafe to drink. How does water use impact the environment? Less Water Affects the Environment When reservoir water levels […]
Is freezing point depression positive or negative?
Is freezing point depression positive or negative? The change in the freezing point is proportional to the amount of solute added. This phenomenon is called freezing point depression. The change in the freezing point is defined as: ∆Tf = Tf,solution − Tf,solvent. ∆Tf is negative because the temperature of the solution is lower than that […]
What does emission mean?
What does emission mean? An emission is something that has been emitted—released or discharged. In general, emissions consist of things like gas, liquid, heat, sound, light, and radiation. This exhaust is just one form of carbon emissions—greenhouse gases from various sources that are known to contribute to global warming and climate change. What is emissions […]
Why is light important for humans?
Why is light important for humans? Earth has been bathed with light from the Sun ever since; it is our most important source of energy. Sunlight warms us, causes weather patterns, allows plants to manufacture oxygen and our food from carbon dioxide and water, and it allows us to find our way around in the […]
