Ring is made up off copper.

Explanation:

Given data:

Mass of ring = 89.2 g

Volume of water = 10 mL

Volume of water + ring = 20 mL

Ring is made up of = ?

Solution:

Volume of ring = (Volume of water + ring) - Volume of water

Volume of ring = 20 mL - 10 mL

Volume of ring = 10 mL

Density:

Density = mass/volume     ( 1 mL = 1 cm³)

d = 89.2 g/  10cm³

d = 8.92 g/cm³

Thus, ring is made up off copper.

a pan containing water is placed in a positio n where it is exposed to a 10 mile per hour wind. the pan contains a uniform depth of 1.27 cm of water, is quite wide, and has a length of 2.44 m in the wind direction. the water in the pan is at a constant temperature of 15.5 °c.
