Is 99.4 a fever under the arm? It’s normal for your body temperature to fluctuate throughout the day. But in general, if you’re an adult and your temperature is above 100.4°F (38°C), you have a fever. What body temp is too low? Hypothermia is a medical emergency that occurs when your body loses heat faster […]
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 […]
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 […]
What are the organelles of cell?
What are the organelles of cell? An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins. […]
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 […]
Is a compass reliable?
Is a compass reliable? Overall, Consumer Reports gave the 2018 Compass a reliability rating of 11%, the lowest of all SUVs in its segment. The 2019 and 2020 models of the Compass have a higher predicted reliability score of about 3 out of 5, but that may change as owners drive their Compasses around some […]
