Why is healthcare an imperfect market? The market for health-care services is considered an imperfect market because — 1)Health care is a heterogeneous product, as the patient can experience a range of outcomes; 2) Patients who are insured have third-party payers covering their direct medical expenses; and 3) A “market price” is lacking, i.e., no […]
What is the direction of the magnetic lines of force?
What is the direction of the magnetic lines of force? Lines of force always form individual CLOSED LOOPS around the magnet. Lines of force have a definite DIRECTION from North to South. Lines of force that are close together indicate a STRONG magnetic field. Is a magnet made with iron nickel or cobalt? There is […]
What is the most frequently cited cause of multiple vehicle crashes?
What is the most frequently cited cause of multiple vehicle crashes? In fact, the National Highway Transportation Safety Administration (NHTSA) reports more than one out of four of all traffic fatalities and almost 17 percent of all fatal crashes in 2017 resulted from speeding. When a traffic collision does not lead to death, the most […]
What does the coefficient of static friction depend on?
What does the coefficient of static friction depend on? Already Coulomb presented experimental evidence that the static coefficient of friction may depend on time, on normal force, on the contact size, on the nature of contacting materials, and on the presence of intermediate lubricant layers. What is the static coefficient of friction? The coefficient of […]
What are the 4 parts of an animal cell?
What are the 4 parts of an animal cell? The components of a cell and their functions are described: membrane, cytoplasm, nucleus. What is the main function of an animal cell? Functions of Animal Cells A cell carries out all the processes of the body which includes producing energy and storing it, making proteins which […]
What is the density triangle?
What is the density triangle? The triangle is divided into three parts, with density occupying the top portion and mass and volume occupying the bottom two portions. The positions of each element of the triangle show us how they relate to one another through the formula above (Density = Mass / Volume, or ρ = […]
Should I charge my new phone overnight?
Should I charge my new phone overnight? “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.” The official word is to keep your phone charged – […]
Who gave the best definition of economics?
Who gave the best definition of economics? Lionel Robbins (1932) developed implications of what has been termed “[p]erhaps the most commonly accepted current definition of the subject”: Economics is a science which studies human behaviour as a relationship between ends and scarce means which have alternative uses. What is economics and examples? Introduction to Economic […]
How do lysosomes work?
How do lysosomes work? A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis. […]
What are the factors affecting thrust?
What are the factors affecting thrust? FACTORS AFFECTING THRUST The factors that affect the thrust of a gas turbine engine include air density, airspeed/ram effect and engine RPM. Why does thrust decrease as airspeed increases? The faster the aircraft speed, the less acceleration is being created on the intake air. Therefore thrust decreases with increasing […]
