How did you get the measurement of the base? The bases of cylinders and cones are circular. The area of a circle is equal to the circle’s radius, r, squared then multiplied by a constant called pi: A = pi x r2. For example, given a cylinder with a radius of 2 inches, you can […]
What are reactants examples?
What are reactants examples? Reactants are substances initially present in a chemical reaction that are consumed during the reaction to make products. Some chemical reactions go to completion, resulting in all of the reactants becoming products. These reactions are said to be irreversible. For example, burning methane in oxygen is irreversible. What are the 7 […]
Is flammability a physical or chemical property?
Is flammability a physical or chemical property? Chemical properties are properties that can be measured or observed only when matter undergoes a change to become an entirely different kind of matter. They include reactivity, flammability, and the ability to rust. Is odor a physical or chemical property? Properties that can be determined without changing the […]
What is energy that Cannot be created or destroyed?
What is energy that Cannot be created or destroyed? The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. What happens to the soul 40 days after death? The 40 days […]
What is the difference between carbon cycle and nitrogen cycle?
What is the difference between carbon cycle and nitrogen cycle? Carbon Cycle: Carbon cycle is a series of processes by which compounds of carbon are interconverted in ecosystems. Nitrogen Cycle: Nitrogen cycle is the series of processes by which nitrogen and its compounds are interconverted in ecosystems. What are the two major types of biogeochemical […]
Which bird can fly without flapping wings?
Which bird can fly without flapping wings? albatross Do birds sleep while flying? Due to the lack of studies monitoring the sleep patterns of flying birds, these hypotheses had previously been left unconfirmed. Now, however, according to a new study from the Max Planck Institute for Ornithology, researchers have finally found evidence that birds do […]
What are three sources of geothermal energy?
What are three sources of geothermal energy? Geothermal energy finds its way to the earth’s surface in three ways: Volcanoes and fumaroles (holes in the earth where volcanic gases are released) Hot springs. Geysers. How deep do you have to go for geothermal? For a horizontal loop you only need to dig between 6 – […]
Why doesnt horizontal motion affect vertical motion?
Why doesnt horizontal motion affect vertical motion? The horizontal velocity remains constant, because there is no acceleration in that direction. The length of the horizontal velocity vector doesn’t change. THE VERTICAL & HORIZONTAL MOTIONS ARE INDEPENDENT. THE HORIZONTAL VELOCITY DOES NOT AFFECT THE VERTICAL MOTION. Does velocity change with angle? When an object is projected […]
What are 5 galaxies in the Local Group?
What is solenoid what is the direction of lines of force around it?
What is solenoid what is the direction of lines of force around it? Turning the solenoid around means that all field lines either point outwards or they all point inwards. Moving the solenoid along the axis means this happens for every little bit of the solenoid. But if all the field lines point outwards everywhere, […]
