What forms does water take through this cycle? The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. How […]
Can you use an accelerometer to measure force?
Can you use an accelerometer to measure force? Accelerometers work by detecting forces. We look at the force acting on a small mass, divide it by the object’s mass, and calculate the force per unit mass. The electronic accelerometer is well suited for recording these forces. Can an accelerometer measure force? An accelerometer is an […]
Who benefits from photovoltaic cells?
Who benefits from photovoltaic cells? Electricity produced by solar cells is clean and silent. Because they do not use fuel other than sunshine, PV systems do not release any harmful air or water pollution into the environment, deplete natural resources, or endanger animal or human health. Photovoltaic systems are quiet and visually unobtrusive. How long […]
Which of the following is the primary function of osteoclasts?
Which of the following is the primary function of osteoclasts? Osteoclasts are large multinucleated cells with a myeloid lineage, which have the function of clearing away mineralized and calcified constituents of the bone matrix which are aged or damaged. What happens through the action of osteoclasts? Osteoclasts resorb bone through the production of proteolytic enzymes […]
How do you calculate the force to push an object?
Should carrots float or sink?
Should carrots float or sink? What’s happening in there? The carrot is more dense than fresh water so the carrot sinks in fresh water. When salt is dissolved in the water, the density of the water increases until the salt water becomes more dense than the carrot which makes the carrot float in the salt […]
Can you charge a conductor?
Can you charge a conductor? Explanation: While you can charge a dielectric (non conductive, like plastic) object rubbing, you cannot charge a conductor (like a metal) rubbing. If you add a charge in one zone of the conducting object, the other charges will automatically re-arrange to neutralize the charge. Is salt water an insulator? For […]
What type of relationship is there between wavelength and frequency?
What type of relationship is there between wavelength and frequency? Frequency and wavelength have both direct and inverse relationships. For instance, if two waves are traveling at the same speed, they are inversely related. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. This is […]
