How does the ear transfer information to the brain? The cochlea is filled with a fluid that moves in response to the vibrations from the oval window. As the fluid moves, 25,000 nerve endings are set into motion. These nerve endings transform the vibrations into electrical impulses that then travel along the eighth cranial nerve […]
What is the frequency of a radio wave?
What is the frequency of a radio wave? Radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. The wavelengths of radio waves range from thousands of metres to 30 cm. These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (109 Hz). What is […]
What is power in sample size calculation?
What is power in sample size calculation? Power calculations tell us how many patients are required in order to avoid a type I or a type II error. The term power is commonly used with reference to all sample size estimations in research. Strictly speaking “power” refers to the number of patients required to avoid […]
What are the steps of implementing public policy?
What are the steps of implementing public policy? A policy established and carried out by the government goes through several stages from inception to conclusion. These are agenda building, formulation, adoption, implementation, evaluation, and termination. How does government implement policy? Policy implementation can be seen as a process of bargaining. Implementation becomes a process of […]
Is the reactant which has the lowest coefficient in a balanced equation?
Is the reactant which has the lowest coefficient in a balanced equation? limiting reactant Do you use limiting reagent to calculate theoretical yield? A limiting reagent is a chemical reactant that limits the amount of product that is formed. The limiting reagent gives the smallest yield of product calculated from the reagents (reactants) available. This […]
What are the 5 basic assumptions of ideal gases?
What are the 5 basic assumptions of ideal gases? The kinetic-molecular theory of gases assumes that ideal gas molecules (1) are constantly moving; (2) have negligible volume; (3) have negligible intermolecular forces; (4) undergo perfectly elastic collisions; and (5) have an average kinetic energy proportional to the ideal gas’s absolute temperature. Which one of the […]
What are the four sub energy levels?
What are the four sub energy levels? There are four types of orbitals that you should be familiar with s, p, d and f (sharp, principle, diffuse and fundamental). Within each shell of an atom there are some combinations of orbitals. How many electrons are allowed in the third shell? eight electrons How many electrons […]
How often do turboprop engines fail?
How often do turboprop engines fail? The Federal Aviation Administration (FAA) was quoted as stating turbine engines have a failure rate of one per 375,000 flight hours, compared to of one every 3,200 flight hours for aircraft piston engines. What is the fastest turboprop? The Piaggio Avanti EVO is the fastest twin turboprop in production, […]
What are the 4 goals in psychology?
What are the 4 goals in psychology? So as you have learned, the four primary goals of psychology are to describe, explain, predict, and change behavior. In many ways, these objectives are similar to the kinds of things you probably do every day as you interact with others. Is Psychology a good career? Psychology is […]
What are the two factors that influence the formation of rust?
What are the two factors that influence the formation of rust? Factors that Affect the Rusting of Iron Moisture: The corrosion of iron is limited to the availability of water in the environment. Acid: if the pH of the environment surrounding the metal is low, the rusting process is quickened. Salt: Iron tends to rust […]
