What is the best angle for a propeller? around 2 to 4 degrees What is the greatest force on a propeller? Centrifugal force is a physical force that tends to throw the rotating propeller blades away from the hub. This is the most dominant force on the propeller. Torque bending force, in the form of […]
What is Coriolis effect and how does it affect weather?
What is Coriolis effect and how does it affect weather? Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) […]
Which is more elastic veins or arteries?
Which is more elastic veins or arteries? In arteries, the tunica media, which contains smooth muscle cells and elastic tissue, is thicker than that of veins so it can modulate vessel caliber and thus control and maintain blood pressure. Larger arteries are typically elastic and smaller arteries are more likely to be muscular. What are […]
How is fan efficiency calculated?
How is fan efficiency calculated? Fan efficiency is defined as the air power divided by the fan input power. Both Static and Total Efficiency can be calculated from fan performance data as follows: wg BHP = Fan power input, hp Static and total fan efficiency (Figure 1) can be plotted along with the fan curve. […]
How long does 4 miles take to run?
Which will increase the appearance of noise in a digital image assuming only the named factor in each response is changed?
Which will increase the appearance of noise in a digital image assuming only the named factor in each response is changed? Which will increase the appearance of noise in a digital image, assuming only the named factor in each response is changed? High kVp technique. How is signal maximized to a digital image receptor? X-ray […]
Why is cloning wrong?
Why is cloning wrong? Human beings should not be cloned for several reasons that are going to be further discussed in this op-ed: cloning is a risky, imperfect procedure, it does not create an exact copy of an individual, and it poses ethical concerns by using human beings as a means to an end, opening […]
What is a controlled variable in science?
What is a controlled variable in science? A control variable is anything that is held constant or limited in a research study. It’s a variable that is not of interest to the study’s aims, but is controlled because it could influence the outcomes. What does control mean in science examples? A scientific control is an […]
What happens when the width of the slit is increased?
What happens when the width of the slit is increased? If the width of the slit is increased in diffraction most of the light will pass through the slit without getting diffracted. As a result, the overlap because of diffraction reduces and lesser and narrower fringes are formed. Does frequency affect diffraction? High frequency sounds, […]
What are the examples of eukaryotic cells?
What are the examples of eukaryotic cells? Examples of Eukaryotic Cells All animals, plants, fungi, and protists are eukaryotic cells. Their cells are organized into compartmentalized structures such as nuclei, mitochondria, chloroplasts, and Golgi bodies. What are eukaryotic cells give two examples? Eukaryotic Cell. Eukaryotic cells are defined as cells containing organized nucleus and organelles […]
