Why is universal health care bad? What Are the Disadvantages of Universal Health Care? A common criticism of universal health care is that the overall quality and variety of care declines. In some countries with universal health care, patients see long wait times or even have to wait months to be seen at all. Universal […]
What happens when an insulator is placed in an electric field?
What happens when an insulator is placed in an electric field? When an insulator, also called the dielectric, is placed in an electric field, it gets polarised. The polarised dielectric reduces the effective electric field. Can an insulator have an electric field? We define a conductor as a material in which charges are free to […]
How many billion years did it take for humans to appear on Earth?
How many billion years did it take for humans to appear on Earth? Recognizable humans emerged at most 2 million years ago, a vanishingly small period on the geological scale. The earliest undisputed evidence of life on Earth dates at least from 3.5 billion years ago, during the Eoarchean Era, after a geological crust started […]

What is secondary pollutants give examples?
What is secondary pollutants give examples? Examples of a secondary pollutant include ozone, which is formed when hydrocarbons (HC) and nitrogen oxides (NOx) combine in the presence of sunlight; NO2, which is formed as NO combines with oxygen in the air; and acid rain, which is formed when sulfur dioxide or nitrogen oxides react with […]

What is energy stored in capacitor?
What is energy stored in capacitor? Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor. We must be careful when applying the equation for electrical potential energy ΔPE = qΔV to a capacitor. Remember that ΔPE is the potential energy […]
