How long do rechargeable batteries last if not used? two to three year How do I know if my rechargeable batteries are still good? Yes – just check the cell voltage. NiMH are fully discharged at ~1V, so if any of your cells are going down to this quickly (after a few cycles) then they’re […]
What is positive and negative charge in atoms?
What are examples of ratio variables?
What are examples of ratio variables? Examples of ratio variables include: enzyme activity, dose amount, reaction rate, flow rate, concentration, pulse, weight, length, temperature in Kelvin (0.0 Kelvin really does mean “no heat”), survival time. What are the 5 most common process variables? The most common process variables fall into five major types: level, flow, […]
Is jealousy a sign of cheating?
Is jealousy a sign of cheating? They get overly jealous If your partner gets irrationally jealous, it may be an indicator that they are transferring their own sense of guilt on to you. This type of projection is a classic way that cheaters try to cover up their own misdemeanors. What are the first signs […]
Do elements in Group 1 gain or lose electrons?
Do elements in Group 1 gain or lose electrons? All Group 1 atoms can lose one electron to form positively charged ions. For example, potassium atoms do this to form ions with the same electron configuration as the noble gas argon. Group 2 atoms lose two electrons to form positively charged ions. Most elements in […]
What is Charles Law in simple terms?
What is Charles Law in simple terms? Charles’s law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant. It is a special case of the general gas law and can be derived from the kinetic theory of gases under the […]
What are the causes and effects of eutrophication?
What are the causes and effects of eutrophication? “Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”. What can humans do to […]
Where is UV found?
Where is UV found? UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. What is UV color? UV light has a shorter wavelength than visible light. […]
Why does oil make a rainbow in water?
What is the relationship between air pressure and weather?
What is the relationship between air pressure and weather? Atmospheric pressure is an indicator of weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. How pressure affects the wind flow? Air Pressure and Winds Air that moves horizontally between […]
