Density is a measure of both how massive those molecules are, and how closely packed together they are. If the object’s total density is greater than that of water, it […]
What affects period of a spring?
What affects period of a spring? The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant. What is the formula for oscillation? The period formula, T = 2π√m/k, gives the exact relation between the oscillation time T and the […]

Why animals can reproduce in large number?
Why animals can reproduce in large number? Animals have limited amounts of energy they can use for reproduction. Animals with high fecundity spend their energy in the production of many offspring that do not require much care. Alternatively, animals with low fecundity produce fewer offspring, and have more energy to care for those offspring. What […]
What is an outlier on a scatter diagram?
What is an outlier on a scatter diagram? An outlier is defined as a data point that emanates from a different model than do the rest of the data. If the outlier is omitted from the fitting process, then the resulting fit will be excellent almost everywhere (for all points except the outlying point). What […]
