Answer:
Explanation:
A )
When empty , H₀ length of barge is inside water .
volume of barge inside water = A x H₀
Weight of displaced water = AH₀ x ρ x g
Buoyant force = weight of displaced water = AH₀ ρg
B)
It should balance the weight of barge
Weight = buoyant force
Weight = AH₀ ρg
mass of barge = weight / g
weight / g = AH₀ ρ
= 550 x .55 x 1000
= 302500 kg
Ω = 2000 rpm, initial angular speed.
t = 30 s, the time for the wheel to come to rest.
Calculate the angular deceleration, α.
w - αt = 0
(209.4395 rad/s) - (α rad/s²)*(30 s) = 0
α = 6.9813 rad/s²
The angular distance traveled, θ, is given by
ω² - 2αθ = 0
θ = ω²/(2α)
= 209.4395²/(2*6.9813)
= 3141.6 rad
The number of revolutions is
3141.6/(2π) = 500
Answer: 500 revolutions

(GABS) Overnight, all of the particles settled down to the bottom , and the larger particles were on the bottom and the smaller particles were on the top. Therefore, clay was on top, hummus was in the middle, and soil was on the bottom.
Particles dissolve is an unique way
A) seems more likely and work in unity.
