What is the resolving power of a compound microscope? The resolving power is the capacity of an instrument to resolve two points that are close together. The resolving power of a compound microscope is 0.25μm. How do you increase the magnification of a compound microscope? In order to increase the magnifying power of a compound… […]
What is egg drop experiment?
What is egg drop experiment? The Classic “Egg-Drop” experiment has been a standard in science instruction for many years. Essentially, students are asked to construct some type of container that will keep a raw egg from cracking when dropped from ever-increasing elevations. What happens during an egg drop? While at rest, the egg has potential […]
Are rivers and oceans landforms?
Are rivers and oceans landforms? Examples of landforms include oceans, rivers, valleys, plateaus, mountains, plains, hills and glaciers. Landforms do not include manufactured features, such as canals, ports and harbors, nor geographic features such as deserts and forests. Landforms originate from these geological processes. What are the largest bodies of water called? The Pacific Ocean […]
What are the big ideas of physical science?
What are the big ideas of physical science? Among the physical sciences are astronomy, which studies the universe beyond Earth; physics, which studies matter and energy and their interactions; chemistry, which studies the properties of substances and how they change; and the Earth sciences, which study Earth itself as well as its atmosphere and waters. […]
What is the difference between two consecutive nodes?
What is the difference between two consecutive nodes? Hence we can say that the phase difference between the particles vibrating between two consecutive nodes is zero. What is the least distance between two consecutive nodes? In a stationary wave, the distance between two successive nodes(anti-nodes) is one half wavelength. Therefore, the distance between a node […]
Which two ways can a permanent magnet can lose its magnetism?
Which two ways can a permanent magnet can lose its magnetism? (Why is a non-permanent, but long lasting, magnet called a permanent magnet?) magnet is cut in two?) Permanent magnets can lose their magnetism if they are dropped or banged on enough to bump their domains out of alignment. How do you scare off sharks? […]
Can you overcharge a camera battery?
Can you overcharge a camera battery? Battery chargers supplied with Sony® cameras are designed to shut off when the battery reaches full charge. For this reason, InfoLithium® and lithium-ion batteries will not be overcharged. How long does a camera battery take to charge? 2 hours Can you leave a camera battery charging overnight? Leaving it […]
What is the brightness or dullness of a color?
What are the names of various sources of control valve noise?
What are the names of various sources of control valve noise? Understanding Control Valve Noise The noise can be generated in three basic ways: by the mechanical vibration of valve components, by turbulent gas flow (aerodynamic noise), or by cavitating liquid flow (hydrodynamic noise). What is noise pollution and its sources? Noise pollution is defined […]
What are the different theories of plate tectonics?
What are the different theories of plate tectonics? Three-dimensional diagram showing crustal generation and destruction according to the theory of plate tectonics; included are the three kinds of plate boundaries—divergent, convergent (or collision), and strike-slip (or transform). What are the disadvantages of divergent plate boundaries? Effects that are found at a divergent boundary between oceanic […]
