What percentage of C 14 remains after 3 half lives? Explanation: After 1 half-life, 12 of the C-14 would remain. After 2 half-life, 12 of the 12 of the C-14 = 14 of the C-14 would remain. After 3 half-life, 12 of the 14 of the C-14 = 18 of the C-14 would remain. What […]

Do antibiotics weaken immune system against viruses?
Do antibiotics weaken immune system against viruses? However, antibiotics can also have harmful side effects, increase bacterial resistance, and sometimes even work against your immune system. Antibiotics are not effective against viruses, and overall, they are widely overprescribed and often unnecessary — here’s how to know if you should be taking them. Do antibiotics weaken […]
Is charging by conduction permanent?
Is charging by conduction permanent? Charging by conduction gives the previously uncharged object a permanent charge. An uncharged object can also be charged using a method called charging by induction. This process allows a change in charge without actually touching the charged and uncharged objects to each other. What is positive and negative charges? There […]
Is 18k magnetic?
What is the two properties of gravity?
What is the two properties of gravity? Property 1: The gravitational force is a long-range force, which exists between two particles, regardless of the medium that separates them. Property 2: The gravitational force is directly proportional to the product of the mass of the two bodies. This means a larger mass will yield a larger […]
Is tidal energy affected by the sun?
How do humans interact with the atmosphere?
How do humans interact with the atmosphere? There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase … […]
What is perturbation technique?
What is perturbation technique? A mathematical technique to eliminate linear terms in an equation in order to retain the nonlinear (turbulence) terms. Variables such as potential temperature (θ) or velocity (U) can be partitioned into mean (slowly varying) and perturbation (rapidly varying) components. Why do we use perturbation? Perturbation is used to find the roots […]
