Explanation:
Given:
- specific heat of ice,
- latent heat of fusion of ice,
- specific heat of water,
(a)
- mass of snow,
- initial temperature of snow,
- Final temperature of the consumed mass,
<u>Now the energy absorbed from the body after eating this snow:</u>
(b)
<u>Energy absorbed from the body in melting the ice is the total latent heat:</u>
(c)
- initial temperature of water,
- final temperature of water,
<u>Now, the amount of energy invested by body for the water at this condition:</u>
We're going to remedy it with the parallelogram law.
= one hundred eighty - 30 - 70 = eighty degrees
R = sqrt(2^2 + 3^2 - 2(2)(three) cos(80)
R = three.30 kN, we can conclude now that the value of the ensuing of R is 3.30 kN
sin
/3 = sin(eighty)/three.304 = 63.4 stages
3.3 kN
180 + 33.4 = 213.4 degrees
63.4 - 30 = 33.4
R = sqrt(2^2 + 3^2 - 2(2)(three) cos(80)
R = three.30 kN, we can conclude now that the value of the ensuing of R is 3.30 kN
sin
3.3 kN
180 + 33.4 = 213.4 degrees
63.4 - 30 = 33.4
