Answer:

Resultant = 3.05N

Explanation:

$r = \sqrt{{5}^{2} + 5^{2} - 2(5)(5) \cos(120) }$

$r = \sqrt{25 + 25 - 50(0.8142)}$

$r = \sqrt{50 - 40.71} = \sqrt{9.29}$

$r = 3.05$

The latent heat of vaporization for ethyl alcohol is 854 J/g. The amount of energy, rounded to the nearest whole number, needed

Lorico [155]

Answer:

4441 J

Explanation:

The amount of energy needed to change the ethyl alcohol from liquid to gas state is given by

$Q=m \lambda_v$

where

m = 5.20 g is the mass of the alcohol

$\lambda_v = 854 J/g$ is the latent heat of vaporization of the substance

Substituting the numbers into the formula, we find:

$Q=(5.20 g)(854 J/g)=4,441 J$
