Can you think of a device that converts electrical energy into heat? Correct answer: An oven converts electrical energy into heat energy, a toaster concerts electrical into heat energy, and an alarm clock has an output of light and sound energy that is converted from electrical energy. What type of energy does a light bulb […]
Can light pass through matter?
Can light pass through matter? Transmission of light occurs when light passes through matter. As light is transmitted, it may pass straight through matter or it may be refracted or scattered as it passes through. When light is refracted, it changes direction as it passes into a new medium and changes speed. What material can […]
What is the slope of a position Time Squared graph?
What is the slope of a position Time Squared graph? time squared is if you have motion with constant acceleration and zero initial velocity. In such case the graph of distance vs time squared will be a straight line whose slope is the acceleration. Can position time graph have negative slope? Yes. The slope of […]

What is the relationship between buoyancy and density?
What is the relationship between buoyancy and density? Buoyant force is directly proportional to the density of the fluid in which an object is immersed. Buoyancy is the tendency to rise or float in a fluid. The upward force exerted on objects submerged in fluids is called the buoyant force. where ρ is the density, […]
Why is yeast considered a fungus and not a bacteria?
Why is yeast considered a fungus and not a bacteria? Yeast are single-celled microorganisms that are classified, along with molds and mushrooms, as members of the Kingdom Fungi. Yeasts are evolutionarily diverse and are therefore classified into two separate phyla, Ascomycota or sac fungi and Basidiomycota or higher fungi, that together form the subkingdom Dikarya. […]
