Answer:
Price=$7×10⁷
Explanation:
Step 1: Estimate the volume of the pile,
Step 2: Multiply it by the density to get its mass
Step 2: Then multiply the mass by the price per gram to get the total price
So
The average pile dimensions are=45.7×45×172.7
Price=m×$10
Price=(7×10⁶)×$10
Price=$7×10⁷
Answer:
Explanation:
m = Mass of object =
m' = Mass of water =
= Density of object
= Density of water
Weight of the water displaced is the force in the case of floating objects
According to the question
In the case of floating objects
The ratio of the density of the object to that of water is
Answer:
Explanation:
Begin by remembering that at the stone's max height, the final velocity there is 0. Being in possession of that information along with the fact that the pull of gravity due to acceleration is -9.8 m/s/s, we can use the equation
Δx where v is the final velocity, v₀ is the initial velocity, a is the pull of gravity, and Δx is the displacement. Filling in:
0 = v₀² - 98 so
98 = v₀² and
v = 9.9 m/s Now we can put that into the KE equation.
and
so
m = .20 kg
