Q1Mass, Weight and DensityFree sample

A student wishes to find the density of a stone. He uses a measuring cylinder and a spring balance with a scale marked in newtons. The measuring cylinder, spring balance and stone are shown in Fig. 1.1.

Fig. 1.1

The student knows that the gravitational field strength is $10\ \text{N/kg}$ .

(a)

Describe how the student uses the spring balance to find the mass of the stone.

(b)

Describe how the student uses the measuring cylinder to find the volume of the stone.

(c)

The mass of the stone is $150\ \text{g}$ and its volume is $70\ \text{cm}^3$ .
Calculate the density of the stone.

density of stone = ______

(d)

The stone is taken to another place, where the gravitational field strength is less than $10\ \text{N / kg}$ . State how this affects the mass and the weight of the stone.
