Answer:
60 ft
Explanation:
The tree man and their shadow system forms two similar right angle triangles.
the figure is in the attachment.
let ∠BAC= θ
Therefore, in triangle ABC
tanθ = BC/AC= 35/75= 7/15
now in ΔAEF also
tanθ = EF/AE = 7/75-x= 7/15
solving we get x=60 ft
Now AC and FA are the shadows of the tree and the man respectively.
now FA =75-x=75-60= 15 ft
Therefore, the man must stand at a distance of 60 ft from the tree can you stand and still be completely in the shadow of the tree
Answer:
mass = 0.44 Kg
Explanation:
given,
Calories contain in the strawberry yogurt = 255 calories
1 Calorie = 4186 J
latent heat of vaporization = 2.42 x 10⁶ J/Kg
mass of perspiration = ?
Energy = 255 calories
Energy = 255 x 4186
= 1067430 J
Energy = mass x latent heat of vaporization
mass = 0.44 Kg
