What is the perimeter of a sector? The formula for the perimeter of the sector of a circle is given below : Perimeter of sector = radius + radius + arc length. Perimeter of sector = 2 radius + arc length. What is sector area formula? The formula for sector area is simple – multiply […]
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 […]
What is wave interference and what two types are there?
What is wave interference and what two types are there? There are two types of interference: constructive and destructive. Constructive interference occurs when the wave amplitudes reinforce each other, building a wave of even greater amplitude. Destructive interference occurs when the wave amplitudes oppose each other, resulting in waves of reduced amplitude. What are sources […]
How does friction affect total mechanical energy?
How does friction affect total mechanical energy? Mechanical energy is reduced due to friction and converted to heat. This is the reason why there is an increase in temperature in objects that move against each other. The role of friction in a closed system is to convert a part of the total energy to heat. […]
Can quasars destroy galaxies?
Can quasars destroy galaxies? However, a series of new papers suggests, the very same radiation that puts quasars on our maps of the universe may be devastating the galaxies that host the insatiable objects. What is the hardest metal on earth? tungsten What is the softest rock in the world? talc What’s the hardest stone […]
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 […]
Is pumice toxic?
Is pumice toxic? Pumice is an excellent filler. It is non-crystalline by nature, non-toxic and non-hazardous. What can I do with leftover lava rocks? 4 Uses for Lava Rock BBQ. Lave rock is used in gas barbecues. Landscape. Lava rock can make effective landscaping in a flower bed or border. Aquarium. Lave rock is often […]
Why is the tundra worth saving?
Why is the tundra worth saving? Why is the Tundra important to protect? The tundra is important to protect because it acts as a carbon sink by absorbing carbon dioxide from the environment and helping to counteract the detrimental effects of carbon emissions. Where are tundras found? The tundra is a treeless polar desert found […]
