Can a body have constant velocity but still a varying acceleration explain? No, a body can not have its velocity constant, while its speed varies. Rather, it can have its speed constant and its velocity varying. For example in a uniform circular motion. What is acceleration always in the direction of? Keep in mind that […]
How do we use dimensional analysis in everyday life?
How do we use dimensional analysis in everyday life? We use conversions in everyday life (such as when following a recipe) and in math class or in a biology course. When we think about dimensional analysis, we’re looking at units of measurement, and this could be anything from miles per gallon or pieces of pie […]
Why do solid not flow?
Why do solid not flow? They are held tightly together by strong forces of attraction. They are held in fixed positions but they do vibrate. Because the particles don’t move, solids have a definite shape and volume, and can’t flow. Because the particles are already packed closely together, solids can’t easily be compressed. Why does […]
What does art nouveau look like?
What does art nouveau look like? The distinguishing ornamental characteristic of Art Nouveau is its undulating asymmetrical line, often taking the form of flower stalks and buds, vine tendrils, insect wings, and other delicate and sinuous natural objects; the line may be elegant and graceful or infused with a powerfully rhythmic and whiplike force. Which […]
What is an example of a scientific method?
What is an example of a scientific method? Here is another example where the scientific method can be used to study the natural world. Define Purpose: I want to know if a bean plant will grow more quickly outside or inside. Construct Hypothesis: The null hypothesis is that there is no difference between growing a […]
What will happen if ozone layer disappears MCQS?
What will happen if ozone layer disappears MCQS? This natural sunscreen, known as Earth’s ozone layer, absorbs and blocks the majority of the sun’s UV radiation. Without this barrier in place, all of the radiation would reach Earth, damaging the DNA of plants and animals, like us humans. Without plants, the food chain would collapse. […]

How do you find the scale of an image?
How do you find the scale of an image? Calculating Distance and Area You simply measure the distance on the photo (photo distance) and multiply the distance by the scale factor. Remember that scale is always equal to the ratio of the photo distance to the ground distance. Example: The scale of an aerial photograph […]
What is an acceptable level of precision?
What is an acceptable level of precision? Some laboratories believe that a good precision study should include 20 to 50 replicates. The larger the number of replicates, the more confident you can be in the precision results. For example, if the true SD of a method is 1.00, a precision estimate based on 20 replicates […]
