What are the causes of low pump efficiency? Lower efficiencies are due to energy losses caused by friction, leakages originating from pressure differentials within the pump case and losses due to a more complex nature. The efficiency of a particular pump is estimated by determining two values. These values are pump flow rate and total […]
Where are riparian zones located?
Where are riparian zones located? The Riparian Zone Riparian zones are the areas bordering rivers and other bodies of surface water. They include the floodplain as well as the riparian buffers adjacent to the floodplain. Riparian zones provide many environmental and recreational benefits to streams, groundwater and downstream land areas. What is the riparian zone […]

Quantity Ohm’s Law symbol Unit of measure (abbreviation) Voltage E Volt (V) Current I Ampere, amp (A) Resistance R Ohm (Ω) What is the formula for Ohm’s Law Ohm’s law states that voltage is equal to? Ohm’s law states that the voltage or potential difference between […]
What is the Van Helmont experiment?
What is the Van Helmont experiment? In what is perhaps his best-known experiment, van Helmont placed a 5-pound (about 2.2-kg) willow in an earthen pot containing 200 pounds (about 90 kg) of dried soil, and over a five-year period he added nothing to the pot but rainwater or distilled water. What did Van Helmont discover […]
What does a credit score measure?
What does a credit score measure? Credit scores are computed using a formula that considers factors such as payment history, overall debt levels, and the number of credit accounts the individual has open. Scores can determine the interest paid on loans and also be a deciding factor on whether a request for credit is approved […]
What are the limitations of Maxwell-Boltzmann statistics?
What are the limitations of Maxwell-Boltzmann statistics? Limits of applicability Maxwell–Boltzmann statistics are often described as the statistics of “distinguishable” classical particles. In other words, the configuration of particle A in state 1 and particle B in state 2 is different from the case in which particle B is in state 1 and particle A […]
Will Pluto ever hit Neptune?
Will Pluto ever hit Neptune? Answer: No. From 1979 to 1999, Pluto was the eighth planet from the sun. In 1999, it slipped beyond Neptune to become the ninth. But Pluto’s 248-year orbit around the sun takes it 17 degrees above and below the plane in which Neptune and the other planets travel. Is Pluto […]
What type of transport is simple diffusion?
What type of transport is simple diffusion? passive transport What does simple diffusion depend on? A. Simple diffusion does not require energy: facilitated diffusion requires a source of ATP. Simple diffusion can only move material in the direction of a concentration gradient; facilitated diffusion moves materials with and against a concentration gradient. What is an […]
What is the read aloud strategy?
What is the read aloud strategy? Read-aloud is an instructional practice where teachers, parents, and caregivers read texts aloud to children. The reader incorporates variations in pitch, tone, pace, volume, pauses, eye contact, questions, and comments to produce a fluent and enjoyable delivery. What are think aloud evaluation techniques? Another common evaluation technique is “think-aloud”, […]
Are tides affected by centrifugal force?
Are tides affected by centrifugal force? The Effect of Centrifugal Force. It is this little known aspect of the moon’s orbital motion which is responsible for one of the two force components creating the tides. As the earth and moon whirl around this common center-of-mass, the centrifugal force produced is always directed away from the […]
