What is Dry Cell give an example? A dry-cell battery stores energy in an immobilized electrolyte paste, which minimizes the need for water. Common examples of dry-cell batteries include zinc-carbon batteries and alkaline batteries. What is the rate of ZnCl2 in dry cell? The compositions of dry cell electrolyte are 15% ZnCl2 and 27%NH4Cl in […]
What is the basic principle of triangulation?
What is the basic principle of triangulation? In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration. What is strength of figure in triangulation? The […]
What must be applied in order to set a resting body in motion?
What must be applied in order to set a resting body in motion? What must be applied in order to set a resting body in motion?… Potential energy. Work. Force. Which type of radiation is created when the primary beam interacts with matter? Primary radiation is the x-rays that come from the target of the […]
How will you separate iron filings and sugar?
How will you separate iron filings and sugar? By using a magnet, we can separate iron fillings and sugar from their mixture. Iron filings will stick to the surface of the magnet and sugar will be left behind. Which method should a student use to separate iron filings from a bowl of cereal? Crush the […]
Does light have shape?
Does light have shape? A pulse of light can have almost any shape in space and in time, determined by the amplitudes and phases of its frequency components. Surprisingly, single photons can also be generated in a variety of complex shapes. Is light a 2D or 3D wave? Spring waves are examples of 1D waves, […]
What are the two main types of stimuli?
What are the two main types of stimuli? There are two main types of stimulus –the external stimulus and the internal stimulus….These sensory stimuli are activated by external changes. Pain and touch: Pain is the stimulus that can cause a major response from the body. Vision: Vision stimuli are sensed by a special type of […]
What is the difference between a large and a small motor unit?
What is the difference between a large and a small motor unit? A small motor unit is an arrangement where a single motor neuron supplies a small number of muscle fibers in a muscle. Small motor units permit very fine motor control of the muscle. A large motor unit is an arrangement where a single […]
What age is best to move out?
Why do we believe there is dark matter?
Why do we believe there is dark matter? A sufficiently massive and cold gas cloud can collapse under its own gravity to form stars. By contrast, dark matter cannot lose energy by emitting light. Thus, while conventional matter can collapse into dense objects like stars and planets, dark matter remains more diffuse. Does a parallel […]
