Please answer question 22
Q22. While determining the density of a solid sphere a student noted down the following readings :
Mass of the sphere = 63g
Reading of water level in the beaker without sphere in it = 82 ml
Reading of water level with the beaker completely immersed in it = 89 ml
On the basis of these observations, what should be the density of the solid sphere?
Mass = 63 grams = 0.0063 kg
Initial reading = 82 ml
Final reading = 89 ml
Volume of sphere = Amount of water displaced by it
Amount of water displaced by it =
Final reading - Initial reading
= 89 - 82
= 7 ml
Volume = 7 ml = 7 cm³ [ 1 ml = 1 cm³]
Density = Mass / Volume
= 63/7
=9 g/cm³
= 9000 kg/m³ [1g/cm³ = 1000 kg/m³]
Initial reading = 82 ml
Final reading = 89 ml
Volume of sphere = Amount of water displaced by it
Amount of water displaced by it =
Final reading - Initial reading
= 89 - 82
= 7 ml
Volume = 7 ml = 7 cm³ [ 1 ml = 1 cm³]
Density = Mass / Volume
= 63/7
=9 g/cm³
= 9000 kg/m³ [1g/cm³ = 1000 kg/m³]
