2) A 100-m curve is to connect a downgrade of 0.75% to an
upgrade of 0.25%. If the level of the intersection point of the two
grades is 150 m, calculate the necessary data for planning the
curve ??
A series of vertical curves connect a 3% upgrade, a 2%
downgrade, and another 3% upgrade moving west to east. These curves
are designed such that they connect directly to one another (i.e.,
the PVT of the first curve is the PVC of the second curve). If the
design speed of the alignment is 60 mi/h, what is the elevation
difference between the two road segments (i.e., the vertical
difference between the PVC of the first curve and the PVT...
A crest vertical curve begins with a 1.2% upgrade and ends with
a 1.08% downgrade. The PVC is at station 125+00 with an elevation
of 711.10ft and the PVT is at station 131+30. The distance to the
highest point is.............ft from the PVC.
A downgrade of 5.0% meets an upgrade of 4.0%. This curve passes
through the lowest point at 20 metres to the right of the
intersection point
1. Find the length of the curve.
2. The reduced level at chainage 2450m, which is located on the
downgrade, is 214.5m on the gradeline. The reduced level of the
curve at the lowest point is 210m. Find the chainage at the lowest
point.
3. Find the chainages and reduced levels of the two...
In general the it is better to mine a tunnel upgrade (uphill)
rather than downgrade because the upgrade has (a) more favorable
discontinuity orientation (b) water in tunnel will drain away from
tunnel face (c) gravity better assists in mining tunnel face (d)
downgrade from tunnel face speed up muck removal (e) all answers
apply
2) Suppose that the production function is given as: q=L^0.75
K^0.25
a) What is the formula for the average product of labor, AP? in
terms of L and K?
b) What is the formula for the marginal product of labor, MP? in
terms of L and K ?
c) If at the current production, cost minimizing level of
capital, ?=16, and the market price of labor (?) is three times the
rental price of capital (?), what is the cost...
Given that a potential of 0.25 mV is applied to an aluminum
conductor that is 100?m long and has a square cross–sectional area
with width 1?m, answer the following questions. The resistivity of
aluminum is 25 nW×m.
(a)Calculate the electric field.
(b)Calculate the magnitude of the current flowing in the
conductor.
(c)Calculate the resistance of the conductor.
We are learning about the properties of materials right now.
Thanks in advance.
If the allele frequencies of b and B are 0.25 and 0.75
(respectively) what will be the frequency of heterozygotes after
one round of random mating (i.e., allele frequencies in the next
generation)?
Also, what is the frequency of the homozygote bb in the next
generation?

You should use NO MORE THAN 100 mL 0.25 M NH4OH, 4 g Ca(NO3)2·
4H2O, and/or 3 g (NH4)2HPO4. NOTE: This is not a stoichiometric
recipe. Part of the grading for this lab will be based on your
ability to determine appropriate quantities of each reactant.
Clearly show the actual amount of each reactant you intend to use.
Determine the mass or volume of each reactant in the proper
stoichiometric ratio, to synthesize and analyze a sample of calcium
hydroxyapatite....
