At what temperature will oxygen molecules have same rms speed? Vrms=√3KbTm, where m is the molar mass of the gas in kilograms per mole, T is the temperature, K is molar mass gas constant. Therefore, option D is the correct answer and the temperature at which the rms speed of oxygen molecules become just sufficient […]

How can I double my money in 5 years? Similarly, if you want to double your money in five years, your investments will need to grow at around 14.4% per year (72/5). If your goal is to double your invested sum in 10 years, you should invest in a manner to earn around 7% every […]

What is difference between drawing and illustration? A drawing is often an exploratory form of visual art. This means that drawings pay considerable emphasis on observation, problem solving and composition. On the other hand, an illustration is defined as the visual representation to provide emphasis or to accentuate a particular text. What’s the difference between […]

Does weight change on the moon? The weight of an object is a force expressed in Newton (N). Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth. Does an astronauts […]

Will vinegar clean a well point screen? The white vinegar is only mildly corrosive, so your pipes and screen will not be harmed, especially once the vinegar becomes diluted and also if the well materials are SS or PVC. Can I fill a 5000 gallon pool with my well? It’s estimated at 540 gallons per […]

Are bricks strong in tension? Steel has enormous strength in tension while concrete has enormous strength in compression. Compressive strength is measured in Megapascal (MPa). A good mud-brick has a MPa strength of around 1.6 to 1.9 MPa, while a clay-fired brick has an MPa strength of around 14. Concrete ranges between 15 and 25 […]

How many square feet is a 5×5 room? 25 square feet How many sq ft is 5×10? 50 square feet Can a king size bed fit in a 5×5 storage unit? With the capability to hold the contents of a mid-sized bedroom (including boxes), some items that can fit in a 5×10 unit include: Queen […]

What is extrapolation on a graph? Besides being able to show trends between variables, plotting data on a graph allows us to predict values for which we have taken no data. When we predict values for points outside the range of data taken it is called extrapolation. What is an example of extrapolation? Extrapolation is […]

Does biotechnology give more benefits than harm? Biotechnology may carry more risk than other scientific fields: microbes are tiny and difficult to detect, but the dangers are potentially vast. Biotechnology could most likely prove harmful either through the unintended consequences of benevolent research or from the purposeful manipulation of biology to cause harm. Is genetic […]

How does diffusion occur in liquids and gases? In gases and liquids, particles move randomly from place to place. The particles collide with each other or with their container. This makes them change direction. Eventually, the particles are spread through the whole container. Can diffusion happen on a solid in liquid in gas? The spreading […]
