This problem here is an example of inelastic collision where kinetic energy is not conserved but momentum is. We calculate as follows:
m1v1 + m2v2 = (m1 + m2)v3
v3 = m1v1 + m2v2 / m1 + m2
v3 = (30.2)(1000) + (5000)(0) / (30.2 + 5000)
v3 = 6.00 m/s
My teacher said 36m when I asked her
A. A fast moving stream. Water has erode Earth for thousands of years. This was what caused the Grand Canyon. A faster ,owing stream would cause a faster erosion due to the speed and strength of the water itself.
Answer is: <span>when the solute is molecular, not ionic.
When the solute is ionic, formula contains t</span><span>he </span>van 't Hoff factor: ΔTf = Kf · m · i.
Van 't Hoff (i) is <span>the number of dissolved particles the solute produces and it is usually i = 2,3...
</span>For molecular compounds (most non-<span>electrolytes)</span> van't Hoff factor is equal one.
