Question

The density of a substance is 8 g/cm². Now we have a new system in which unit of length is 5cm
and unit of mass 20g. Find the density in this new system​

Answer 1

Answer:

Your answer is :

Explanation:

Given density = 8g/cm3

In the new system, 1 mass unit (m unit) = 20g, 1 length unit (l unit) = 5 cm

thus, 1 v unit = 5^3 cm^3

Using unitary method, 1g = 1/20 m unit

Similarly, 1 cm^3 = 1/125 v unit

Thus by multiplying the corresponding values to those in the given density, we get

New density = (8*1/20)/(1/125) = 50 m unit/ v unit
