Acetone is a flammable solvent used in the making of plastics. The density is 790kg/m3. to convert 790kg/m3 to g/cm3​
Artist 52 [7]

Answer: 0.790 g/cm3

Explanation:

The density of acetone is 790 Kg/m3.

To convert from Kg to g we multiply by 1000 (1 Kg = 1000 g)

To convert from m3 to cm3 we multiply by 10∧6

So, The density of acetone in (g/cm3) = (790 x 1000) / (10∧6) = 0.79 g/cm3

kozerog [31]

Answer:

well, the air in our atmosphere stays there and nothing can get past the last layer. Think of is as a car. if there gets to be too much gas in it, it can harm you. I would also say it is one of the causes of global warming. Also air pollution is a big problem.

A 5.00 kg dog runs towards a skateboard with a speed of 2.50 m/s. The skateboard is initially at rest. The dog jumps onto the sk
ladessa [460]

Answer:

The mass of the skateboard is 1.25 kg.

Explanation:

We have,

Mass of dog, m = 5 kg

Initial speed of dog, u = 2.5 m/s

Initial speed of skateboard, u' = 0 (at rest)

The dog jumps onto the skateboard and both the dog and skateboard move with a speed of 2.00 m/s. It is the common speed of the dog +skateboard, V = 2 m/s. We need to find the mass of the skateboard. Using conservation of momentum as :

mu+m'u'=(m+m')V

m' is mass of skateboard

5\times 2.5=(5+m')2\\\\m'=1.25\ kg

So, the mass of the skateboard is 1.25 kg.
