What happens when the retina detects light? When a photon reaches your eye it passes through the transparent cornea and then through the lens which refracts and focuses the light onto your retina, where the light is selectively detected and absorbed by special photoreceptor cells: the rods and cones. Why do doctors shine a light […]
What is the definition of system approach?
What is the definition of system approach? Systems approach is based on the generalization that everything is inter-related and interdependent. A system is composed of related and dependent element which when in interaction, forms a unitary whole. A system is simply an assemblage or combination of things or parts forming a complex whole. What word […]
Is there no friction on ice?
Is there no friction on ice? When a skate moves over the surface of ice, the friction between the skate and the ice generates heat that melts the outermost layer of ice. But ice is still slippery even when you’re standing still. If you stand on ice without moving, no friction exists to generate heat, […]
How can you identify a metal?
What is the degree measure of each arc along the rim?
How many steps are in the design process?
How many steps are in the design process? five steps What is the design thinking process? Design thinking is a non-linear, iterative process that teams use to understand users, challenge assumptions, redefine problems and create innovative solutions to prototype and test. Involving five phases—Empathize, Define, Ideate, Prototype and Test—it is most useful to tackle problems […]
What are the two factors of gravity and how do they affect gravitational pull?
What are the two factors of gravity and how do they affect gravitational pull? Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them. Objects with greater mass have a stronger force of gravity between them. Objects that […]
Does friction depend on surface area?
Does friction depend on surface area? Friction is a contact force when two surfaces interact. Notice that both of these friction formulas ONLY depend on the coefficient of friction and the normal force. It does not depend the area of contact, it doesn’t depend on the sliding speed. Is friction dependent on mass? Friction DOES […]
What are the major types of chemical reactions?
What are the major types of chemical reactions? Having a thorough understanding of these types of reactions will be useful for predicting the products of an unknown reaction. The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion. What is the difference between a chemical equation and a chemical reaction? Chemical […]
