Can velocity be zero if acceleration is zero? When acceleration is zero then velocity of object can be zero or constant. The body continues to move with its velocity throughout. For e.g if a train is at rest then acceleration is zero and velocity remains zero. Why does velocity change direction zero? The velocity, that […]
What is a heterogeneous mixture?
What is a heterogeneous mixture? A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers. Each of the layers is called a phase. […]
What does it mean when cats sit and stare at you?
What does it mean when cats sit and stare at you? If your cat looks relaxed and calm when staring at you, they’re looking at you for happy reasons and are likely just showing you affection. How do cats choose their human? Cats’ favoritism is just as unpredictable and individual. Your cat’s favorite person might […]
What kind of mixtures can be separated by distillation?
What kind of mixtures can be separated by distillation? Fractional distillation is a method for separating a liquid from a mixture of two or more liquids. For example, liquid ethanol can be separated from a mixture of ethanol and water by fractional distillation. This method works because the liquids in the mixture have different boiling […]
Which ocean hosts the oldest oceanic crust on Earth?
Which ocean hosts the oldest oceanic crust on Earth? Mediterranean Sea What is the age of the oldest oceanic crust on Earth? about 340 million years What is the youngest ocean? Atlantic Ocean Where is the newest oceanic crust found? mid-ocean ridge Why is there no ocean floor much older than 280 million years? While […]
Why is gravity proportional to mass?
Why is gravity proportional to mass? According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons. Most gravitons exist in a cloud around the object. What is the similarities between mass and […]
What is needed for light independent reactions?
What is needed for light independent reactions? After the energy from the sun is converted and packaged into ATP and NADPH, the cell has the fuel needed to build carbohydrate molecules. These energy-carrying molecules travel into the stroma where the Calvin cycle reactions take place. … What is an example of light independent reactions? Explanation: […]
What is the difference between survival of the fittest and natural selection?
What is the difference between survival of the fittest and natural selection? “Survival of the fittest” is a popular term that refers to the process of natural selection, a mechanism that drives evolutionary change. Natural selection works by giving individuals who are better adapted to a given set of environmental conditions an advantage over those […]
How do you find the class interval in a frequency distribution?
How do you find the class interval in a frequency distribution? The steps in grouping may be summarized as follows: Decide on the number of classes. Determine the range, i.e., the difference between the highest and lowest observations in the data. Divide range by the number of classes to estimate approximate size of the interval […]
Can you convert current to voltage?
Can you convert current to voltage? We usually say that the resistor converts the current IIN into a proportional voltage VOUT or it serves as a simple current-to-voltage converter – a linear circuit with transfer ratio k = VOUT/IIN [V/mA]. A bare resistor can convert current into voltage. How do you convert low current to […]
