Achair has a mass of 18g and a density of 150 g/m^3

Answer;

= 0.12 m³ or 12 × 10^4 cm³

Explanation;

Volume = mass /density

Mass = 18 g

Density = 150 g/m³

Volume will therefore be;  18 /150 =  0.12 m³

Volume = 0.12 m³ or 12 × 10^4 cm³

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
