Answer:
its most definitely c. trust me
Explanation:
To find speed you have to divide distance by time. In this case:
5 meters➗3 seconds = about 1.66666666 and so on m/s.
You could round to 1.67 or 1.7 if you'd like.
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
