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 […]
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 […]
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 […]
In which nebula do we live?
What weighs more vodka or water?
What weighs more vodka or water? Dense materials sink, and less-dense materials float. Water is denser than alcohol, so the alcohol floats on top of the water. In higher temperature, the density is lower. Does alcohol and water mix? Because water molecules are polar, any liquid that does not have polar molecules—such as oil—is usually […]
What type of natural selection has occurred?
What type of natural selection has occurred? Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection. Is natural selection true? Natural […]
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 […]
