What is the resistance of an open circuit? An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference. How do you read a 20K ohm meter? The ohm […]
Which of the following best describes an environmental problem that is often linked to fracking?
Which of the following best describes an environmental problem that is often linked to fracking? Which of the following best describes an environmental problem that is often linked to the process of fracking? Fracking operations require large tracts of land, which degrades habitat and harms wildlife. Fracking can increase stream flow and water volume, disrupting […]
What caused the continental shelf?
What caused the continental shelf? Continental shelves were formed in between glacial periods as the ocean flowed over the continents forming shallow areas along the coasts. Turbidity currents are also responsible for the continental rise or the gradual slope of the continental shelf into the abyssal plain. What animals live in the continental shelf? Lobster, […]
How do you express temperature range?
How do you express temperature range? Definitely nothing wrong with the way the temperature range is expressed. When using the degree symbol in expressing a range of temperatures in Celsius or Fahrenheit, both numbers in the range can have the symbol, thus: Water is as a liquid within the 32º – 212º F range • […]
What are four factors that affect the rate of a chemical reaction?
What are four factors that affect the rate of a chemical reaction? There are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. Physical state of the reactants and surface area. Temperature. Presence of […]
Why does Coca Cola sink and Diet Coke float?
How many volts are in 1000 Watts?
What are the characteristics of hazardous waste?
What are the characteristics of hazardous waste? There are four basic characteristics to look at; ignitability, corrosivity, reactivity, and toxicity. Ignitability – According to the EPA, “Ignitable wastes can create fires under certain conditions, are spontaneously combustible, or have a flash point less than 60 °C (140 °F). What is not a hazardous waste? Organic […]
How do you predict ion charges?
How do you predict ion charges? When they gain electrons, they are negatively charged and are named anions. You can predict the charge of an ion by looking at its group number on the periodic table. Groups IA, IIA and IIIA all lose electrons and become positively charged. Groups VA, VIA and VIIA all gain […]
How do I know if I have low estrogen or progesterone?
How do I know if I have low estrogen or progesterone? Telltale indicators of low estrogen include hot flashes and missed periods. But some of these symptoms can also occur as a result of other conditions, including thyroid problems. To determine the cause of low estrogen, a doctor may do a blood test to check […]
