How do you find the inner radius of a pipe? V = V1 – V2 for the volume of the solid, the tube….Tube Formulas in terms of radius and height, r and h: generally A = πr2, for a circle, therefore, A1 = πr12 for the area enclosed by C. A2 = πr22 for the […]
How many deep breaths per minute is normal?
How many deep breaths per minute is normal? So, What Is “Normal Breathing”? Normal breathing at rest is 8-12 breaths per minute. That may not sound like enough, as many of us breathe around 25 breaths per minute. In many cases, this rate of breathing is related to high anxiety and stress levels. What is […]

What ozone layer absorbs Mcq?
What ozone layer absorbs Mcq? Explanation: The ozone layer absorbs the medium frequency UV radiations from the sun and hence protects the life forms at the surface from harm. Are HCFCs ozone depleting? The HCFCs are one class of chemicals being used to replace the CFCs. They contain chlorine and thus deplete stratospheric ozone, but […]
What are the 5 types of catapults?
What are the 5 types of catapults? There are five historical types of catapults: the mangonel, onager, ballista and trebuchet, using three types of motive force: tension, torsion and gravity. Side view of a torsion powered mangonel catapult in the cocked position. Who invented a catapult? Greek Dionysius the Elder Who invented the trebuchet catapult? […]
What are the rules of diving?
What are the rules of diving? The Six Rules Of Scuba Diving Breathe continuously while on scuba. Never hold your breath. Equalise early and often while descending. Ascend slowly from every dive and make safety stops. Continuously monitor depth, time, and pressure. Do not overweight yourself. Dive like a fish (and not like an ape). […]

How do rivers stay full?
How do rivers stay full? Rainwater from mountains collect together and stream down the slope. The stream gradually becomes larger and larger into a river, ultimately emptying into the sea. Rain is constantly feeding the river. If it doesn’t rain for some reason then the river would dry up. How do rivers continue to flow? […]
What happens to density when pressure increases?
What happens to density when pressure increases? Density and pressure/temperature As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases. A decrease in density results in an increased density altitude, whereas an increase in density results in a decreased density altitude. Does density depend on temperature? Temperature Affects […]
