What is the most probable reason why a life jacket helps you float in water? The trapped air weighs much less than the weight of the water it displaces, so the water pushes up harder than the life jacket pushes down, allowing the life jacket to remain buoyant and float. This buoyancy is strong enough […]

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 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 […]

Is eating no meat healthy? The health factor And people who don’t eat meat — vegetarians — generally eat fewer calories and less fat, weigh less, and have a lower risk of heart disease than nonvegetarians do. Even reducing meat intake has a protective effect. Will I get sick if I eat meat after being […]

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 […]

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 […]

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 […]

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 […]

Which Colour deviates more and why? All the colors of white light have different wavelengths and their deviation is also different. Also, the violet color has the least wavelength. Therefore when it travels from one medium to another, then it has the maximum value of the angle of incidence and the violet color will deviate […]

What is the change of state when wax melts? Melting of wax, by itself, involves a change of state from solid to liquid. When the physical state of a substance changes, no new products are formed. Hence, it is a physical change. What state was the wax in before it was heated? solid What will […]
