Question

heey help plz???????A block measuring 20cm by 10cm by 4 cm rests on a flat surface. The block has a weight of 600g. Determine: (a)The minimum pressure it exerts on the surface. (3 Marks (b) The density of the block in kg/Take (g = 10N/kg . (3 Marks

Answer 1

Answer:

a) 300 Pa

b) 750 kgm-³

Explanation:

P = F/A

Minimum pressure exerts when the largest area on the surface,

a) P = (0.6 × 10 ) / ( 20×10 × 10^-4)

= 300 Pa

b) D = m/v

= 0.6/ (20 × 10 × 4 × 10^-6)

= 750kgm^-3
