试题来源: 解析 B。本题考查密度公式的英语表达。ρ表示密度(density),m 表示质量(mass),V 表示体积(volume),密度的计算公式是 ρ = m/V。A 选项是质量等于密度乘以体积;C 选项是体积等于质量除以密度;D 选项是力等于质量乘以加速度。反馈 收藏
The formula for density is: density = mass / volume. This means that if the mass of an object increases while its volume stays the same, its density will also increase. What is the density of a floating sphere? The density of a floating sphere will depend on the density of the ...
The dimensional formula is a technique in Physics, where we represent derived quantities in terms of seven fundamental quantities i.e. Length, Mass, Time, temperature, etc.Answer and Explanation: Data Given We know that density is mass per unit volume i.e. {eq}\rho = \frac{m}{V} {/...
