Is heat or ice best for pinched nerve? The combination of hot and cold increases the circulation of fresh blood to the area, which may help relieve pain. Hold an ice pack over the affected area for about 15 minutes at a time, three times a day to help reduce inflammation. Heat pads can be […]

What is meant by the statement potential difference between A and B is 3v? Answer: If we say the potential difference between two points is 3 volt it does mean that 3 joule of work is done in moving a unit positive charge between those points. What is meant by saying that the potential difference […]

What is going to happen in 2099? Artificial intelligence will move its influence beyond Earth’s limits to the entire Solar System, and then it will move on to other galaxies. Stars, planets, and meteors will be transformed into a structured matter capable of sustaining life. By 2099, machines will be capable of building computers the […]

How do you determine a two-force member? If an element has pins or hinge supports at both ends and carries no load in-between, it is called a two-force member. These elements can only have two forces acting upon them at their hinges. If only two forces act on a body that is in equilibrium, then […]

How do you thank someone for an extremely generous gift? “Thank you very much for your extremely generous donation to me and my family. It is greatly appreciated and I can’t thank you enough. May God bless you and yours.” How do you say thank you on your last day at work? “Dear Colleagues, As […]

Does Fire Insurance Pay arson? Arson is a crime while a fire due to a natural cause is not. One standard provision of fire insurance policies would be the exclusion of fires caused by arson. This means that when your property is damaged due to arson, you will not be entitled to collect any proceeds […]

What does conductivity depend on? What does conductivity depend on? It depends on the concentration, mobility, the valence state of the ionized species in a solution, and the temperature at which a measurement is taken. The higher the concentration of the ions in water, the higher the conductivity. How does thermal conductivity depend on density? […]

What is difference between mean and median? The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. What is the difference […]

What are examples of loud sounds? Loud sound has a high volume while soft sound has a low volume. Banging of a hammer and a car’s horn are examples of loud sounds while playing of a piano and sound of blowing wind are examples of soft sounds. What are the examples of soft sounds? Soft […]

How did you separate the components of salt water solution? For example, water can be separated from salt solution by simple distillation. This method works because water has a much lower boiling point than salt. When the solution is heated, the water evaporates. It is then cooled and condensed into a separate container. What technique […]
