How much pollution does energy produce? It’s a significant body of data given that power generation accounts for about a quarter of global carbon dioxide emissions at 10 billion tonnes per year. Over a quarter of that comes from the 8000 power plants in the United States, making its energy sector the biggest carbon emitter […]
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 […]
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 are the dangers associated with email?

In an email spoofing case, a cyber criminal sends a user an email pretending to be someone the user knows. 2- Email Security Gaps. 3- Domain Squatting. 4- Client-Side Attacks. 5- Malicious Files. 6- Ransomware. 7- Misconfigurations. 8- […]
Where is productive efficiency?
Where is productive efficiency? In long-run equilibrium for perfectly competitive markets, productive efficiency occurs at the base of the average total cost curve — i.e. where marginal cost equals average total cost — for each good. What is meant by productive efficiency? Production efficiency is an economic term describing a level in which an economy […]
Why does the solution conduct electricity when the crystals dissolved in water?
Why does the solution conduct electricity when the crystals dissolved in water? When a crystal of an ionic compound dissolves in water, the ions separate. Again, the ions are free to move – so a solution of an ionic compound in water also conducts electricity. Which compound has the most ionic character? The greatest the […]
What are the natural variables of Helmholtz free energy?
What are the natural variables of Helmholtz free energy? The natural variables are temperature, T, and volume, V . If the temperature and volume are held constant, the system will reach the equilibrium state (pressure, P, and entropy, S) with the minimum Helmholtz free energy. What are the four thermodynamic functions? Four important and useful […]
What is the highest frequency of sound?
What is the highest frequency of sound? 20 kHz Can high frequency sounds kill you? The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure. High-intensity ultrasonic sound […]
What types of waves do doctors use?
What types of waves do doctors use? Transverse Waves in Medicine Describe three ways that the transverse waves of the electromagnetic spectrum are used in medicine. Explain in your own words how the behaviors and characteristics of each of these waves play a role in the practical application. What type of waves does an MRI […]
What is the chemical equation of oxygen?
What is the chemical equation of oxygen? As we inspect this equation we see that there is one carbon atom on each side of the arrow and that there are two oxygen atoms on each side….5.2: Chemical Equations. Element Chemical Formula Hydrogen H2 Oxygen O2 Nitrogen N2 Fluorine F2 What type of reaction is C […]
