Are polar compounds attracted to positive and negative charges? When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don’t, we call them non-polar. Things that are polar can attract and repel each other (opposite charges […]
How do air masses get their properties?
How do air masses get their properties? The properties of air masses are determined by the the underlying surface properties where they originate. Once formed, air masses migrate within the general circulation. Upon movement, air masses displace residual air over locations thus changing temperature and humidity characteristics. What do the properties of an air mass […]
What is the disadvantages of bridge rectifier?
What is the disadvantages of bridge rectifier? The main disadvantage of a bridge rectifier is that it needs four diodes, two of which conduct in alternate half-cycles. Because of this the total voltage drop in diodes becomes double of that in case of centre-tap rectifier, losses are increased and rectification efficiency is somewhat reduced. What […]
What is the formula for volume displacement?
What is the formula for volume displacement? The weight of the displaced fluid can be found mathematically. The mass of the displaced fluid can be expressed in terms of the density and its volume, m = ρV. The fluid displaced has a weight W = mg, where g is acceleration due to gravity. Therefore, the […]
What terminal has the highest fall velocity?
What terminal has the highest fall velocity? The world record terminal velocity was set by Felix Baumgartner, who jumped from 39,000 meters and reached a terminal velocity of 134 km/hr (834 mph). Which Brainly has the lowest threshold velocity? The correct answer is silt. Silt had the lowest threshold velocity. How are oxbows and loess […]
Can nitrogen and bromine form ionic bonds?
Can nitrogen and bromine form ionic bonds? So, they can easily form ionic compound by the complete transfer of electrons. While the other pairs, sodium and potassium are the metals, nitrogen and iodine, chlorine and bromine, helium and oxygen are the non-metals. They do not form ionic bond. Can oxygen and magnesium form an ionic […]
What is the formula for silicon carbide?
What is the formula for silicon carbide? SiC Is silicon carbide a good insulator? Silicon carbide, in its pure form, behaves as an electrical insulator. Yet, electrical ageing, which is the increase in electrical resistivity, could very well affect silicon carbide’s electrical conductivity properties. Is silicon carbide natural? Silicon carbide (SiC), also known as carborundum […]
Is whistleblowing justified?
Is whistleblowing justified? The conditions in which whistle blowing is morally justified are: 1. A product or policy that will commit serious and considerable harm to the public. The employee must have documented evidence that is convincing to a reasonable level so that the facts can be proved to the outside public and to the […]
What are the disadvantages of bioethanol?
What are the disadvantages of bioethanol? What are the disadvantages of bioethanol? Debates surrounding food vs fuel: Some people are concerned that the popularity of biofuel is set to increase food prices across the globe. Efficiency: Biofuel fires tend not to get as hot as their wood-burning alternatives. Cost: Biofuel is often a little more […]
