Where will be the Centre of gravity of a uniform rod lies? The centre of gravity of a uniform rod will lie at the middle point. Centre of gravity is an imaginary point at which weight of the object is taken as the average. What method is used to find the center of gravity of […]
What is solid fuel used for?
What is solid fuel used for? Solid fuel use is defined as the household combustion of coal or biomass (such as dung, charcoal, wood, or crop residues). Worldwide, approximately 50% of all households and 90% of rural households utilize solid fuels for cooking or heating. Is solid fuel heating expensive? ‘ Solid fuel – coal […]
What is the main function of neurotransmitters?
What is the main function of neurotransmitters? Neurotransmitters are often referred to as the body’s chemical messengers. They are the molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles. Communication between two neurons happens in the synaptic cleft (the small gap between the synapses of neurons). What are […]
Are protons positive or negative?
Are protons positive or negative? Protons and Electrons A proton carries a positive charge (+) and an electron carries a negative charge (-), so the atoms of elements are neutral, all the positive charges canceling out all the negative charges. Atoms differ from one another in the number of protons, neutrons and electrons they contain. […]
How do Wedge make work easier?
How do Wedge make work easier? A wedge makes work easier by increasing the force applied to the object, although it applies the force over a shorter distance. This gives the wedge a mechanical advantage greater than 1. What is the difference between a wedge and a screw? Wedges generally concentrate force, usually to split […]
How do you find Q solution and Q reaction?
What happens if gas pressure is too low?
Are the two cylinders similar The diagrams are not drawn to scale?
Are the two cylinders similar The diagrams are not drawn to scale? The diagrams are not drawn to scale. Yes. What does it mean when solids are similar? Two shapes are similar if all their corresponding angles are congruent and all their corresponding sides are proportional. Two solids are similar if they are the same […]
What is the origin of frictional force?
What is the origin of frictional force? Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Friction originates in nanoscale contacts, as the result of new surface formation. The theory explains the generation of frictional force and frictional heating in dry contact. What energy does friction produce? When friction […]
What is happening with the matter in PSII?
What is happening with the matter in PSII? The energy absorbed in PSII is enough to oxidize (split) water, releasing oxygen into the atmosphere; the electrons released from the oxidation of water replace the electrons that were boosted from the reaction center chlorophyll. What is happening with matter in photosystem 1? Photosystem I is an […]
