The fraction of ice submerged when it floats in fresh water is 0.9.
Given that the density of water is 1000 kg/m³ and density of ice is 0.917 gm/cm³.
Converting gm/cm³ to kg/m³ we get, 0.917 gm/cm³ = 917 kg/m³
ρ₁ = 1000 kg/m³, ρ₂ = 917 kg/m³
V₁ = volume of water displaced = xV₂, V₂ = volume of ice submerged
Archimedes principle states that, the buoyant force on the ice will be equal to the weight of the water displaced. Using this principle in the above question.
ρ₁V₁= ρ₂V₂
V₁ = ρ₂V₂/ρ₁
xV₂ = 917 V₂/1000
x = 0.9
Thus, the fraction of ice submerged in water is 0.9.

Answer:
100 N force have to lift for the board to be carried
Explanation:
Given data
L = 3.00 m
F1 = 60.0 N
w = 160 N
to find out
magnitude F2 of force
solution
we know that F1 and F2 sum is equal to weight of board
so that we can say
F1 + F2 = W
so
F2 = W - F1
put the value W and F1
F2 = 160 - 60
F2 = 100 N
so 100 N force have to lift for the board to be carried
Answer:
all atoms will be more stable if they a full valance shell or a full outer most shell or my teacher also tell us that the lucky number is 8 and if an atom has 8 valance electron it will be stable, like the noble gas
Explanation:
Answer:
D is correct.
The upward force on the ball must be the same at both locations:
F = M a = 0 = F(upwards) - F(downwards)
If the ball is not being accelerated the upward force must equal the downward force on the ball.
