Answer:
69.69 g
Explanation:
Evaporation of water will take out latent heat of vaporization. Let the mass of water be m and latent heat of vaporization of water be 2260000 J per kg
Heat taken up by evaporating water
= 2260000 x m J
Heat lost by body
= mass x specific heat of body x drop in temperature
60 x 3500 x .750 ( specific heat of human body is 3.5 kJ/kg.k)
= 157500 J
Heat loss = heat gain
2260000 m= 157500
m = .06969 kg
= 69.69 g
Answer:
Distance(h1) = 12 m
Explanation:
Given
:
Height of cliff (h) = 4m
Time (t) = 1s
Intial velocity (u) = 0m/s
Computation:
Distance(h) = 1/2(g)(t)²
4 = 1/2(g)
g = 8m/s
²
Distance(h1) = 1/2(g)[(t1)²-(t)²]
Distance(h1) = 1/2(8)(3)
Distance(h1) = 12 m
