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
Question
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
