Question

any one know the answer (with explaination) please tell me send it by writing in a paper​

Answer 1

Answer:

1. Mass (m) = 300 g

= 300/1000 kg

= 0.3 kg

Volume (v) = 400 cm³

= 400/1000000 m³

= 0.0004 m³

a. Density in C.G.S Unit = Mass/Volume

= 300/400 g/cm³

= 0.75 g/cm³

b. Density in S.I Unit = Mass/Volume

= 0.3/0.0004 kg/m³

= 750 kg/m³

2. Given,

Mass (m) = 5000 g

Density of wood = 0.8 g/cm³

∴ Density = Mass/Volume

= 0.8 = 5000/Volume

= 0.8Volume = 5000

= 6250 cm³ = Volume

I hope this helps.
