What process occurs in stellar explosion? Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. The term supernova nucleosynthesis is used to describe the creation of elements during the explosion of a massive star or white dwarf. What is the difference between the two types of supernovae? A type […]
What happens to inductor when switch is closed?
What happens to inductor when switch is closed? When the switch is first closed, the current through the inductor is zero, because it cannot change instantaneously. This means that the inductor acts like an open circuit, so all the voltage is across the inductor. The changing magnetic field creates a back emf which acts to […]
What operates best under bright light conditions?
What operates best under bright light conditions? The fovea contains cones that possess high levels of visual acuity and operate best in bright light conditions. What is the process of receiving stimulus energies? The process of receiving stimulus energies from the external environment and transforming those energies into neural energy is called SENSATION. The process […]
What motion is illustrated by a ball thrown horizontally?
What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]
How can barriers to physical activity be overcome?
How can barriers to physical activity be overcome? Lack of time Identify available time slots. Add physical activity to your daily routine. Select activities, such as walking, jogging, or stair climbing that you can do based on the time that you have available (e.g., 5 minutes, 10 minutes, 20 minutes). Take advantage of work physical […]
What does a plastic stopper reduce?
What does a plastic stopper reduce? The vacuum prevents conduction. The tight stopper prevents air from entering or leaving the flask, so convection isn’t possible either. The sealed stopper stops heat getting in by convection; the vacuum stops conduction, and the metal lining between the outer case and the inner chamber stops heat radiating in […]
What are the two main types of steam turbines?
What are the two main types of steam turbines? Two types of steam turbines must be considered, condensing and noncondensing. What is the principle of steam turbine? In simple terms, a steam turbine works by using a heat source (gas, coal, nuclear, solar) to heat water to extremely high temperatures until it is converted into […]
Does the RBE stay constant for different ISO effects?
Does the RBE stay constant for different ISO effects? It follows that RBE cannot be a constant value when taken in the context of the complexities of different tissues within the human body, the heterogeneity of cancer types, and the wide variety of doses used as well as the degree to which Bragg peaks are […]
What is the form of a scatter plot?
What is the form of a scatter plot? A quick description of the association in a scatterplot should always include a description of the form, direction, and strength of the association, along with the presence of any outliers. Form: Is the association linear or nonlinear? Direction: Is the association positive or negative? What does a […]
At what point is the temperature in Fahrenheit three times that in Celsius?
At what point is the temperature in Fahrenheit three times that in Celsius? 80 = 3*26.667, so the degrees in Fahrenheit is 3 times the degrees in Celsius. At what temperature the reading on Kelvin scale is three times that of Celsius scale? Answer. ∴ The temperature of the reading on Kelvin scale is three […]
