Answer:

Explanation:

400nm = 400 x $10^{-9}$ m

1m = 100 cm

400 x $10^{-9}$ m = 400 x $10^{-9}$ x 100 cm

ans : wavelength of light = <u>4x </u> $10^{-5}$ <u> cm</u>

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

If I exert a 203 N force on a 58 kg box, what will the acceleration of the box be?

Anit [1.1K]

Answer:

Explanation:

The acceleration of an object given it's mass and the force acting on it can be found by using the formula

$a = \frac{f}{m} \\$

m is the mass

f is the force

From the question we have

$a = \frac{203}{58} = \frac{7}{2} \\$

We have the final answer as

Hope this helps you
