ACCURATE ANSWERS
Half life
The rate of decay is measured by its
1
The pH number that indicates the greatest acidity is
5KG
Approximate mass of 49N weight is
Atomic nucleus
The atomic number is the number of protons in an atom
Flourine has an atomic weight of 19 and an atomic number of 9. What is the number of
neutrons in the atomic nucleus?
10
An atom has 30 protons and 35 neutrons in its nucleus. It has 30 electrons in its shells. Its
atomic weight would be?
65
,Backfill for use around culverts and pipes consists of
Granular materials
An inspector looks through one end of a drainage pipe. He is most likely checking
Alignment of the pipe
An important consideration in excavation for drainage is the trench width. Why is it
important to keep the trench width to that which is called for by the specifications, and not
larger?
Larger trench widths mean more backfill material, which increases costs.
The main purpose of sampling any material is?
Obtain a small part of a lot to represent the whole.
What is the water cement ratio?
Weight of water/weight of cement
Wet sieve
Used to separate fine grain from coarse grain. It carried out by washing the soil specimen
on a 60pm sieve mesh.
,In soil testing the test used to determine the ratio of the weight of a given volume of
material to the weight of an equal volume of water is known as?
Density check
Slump test of concrete test all but which one of the following? Water cement ratio,
admixture content, strength, durability/workability, water content.
Strength
For a concrete slump test how is the cone to be filled with concrete?
3 equal layers according to volume
How is the bearing of a line notated?
S 23° 30' E
Horizontal distances over sloping ground are usually determined by?
Surveying tape and plumbing bob
A distance between two points 300' apart is measured on a hot day. The tape will show a
length greater than or less than 300'?
Less
, A road has a grade of 2.0% with an elevation of 1252.00 at station 450+20. What is the
elevation at station 455+30?
45530-45020 = 510'
510 x 0.020 = 10.2'
1252.0 + 10.2 = 1262.2
Answer is 1262.2
In topographical maps, the lines drawn to show relief by means of hill shading are called?
Hachures
A freeway rises 25 feet in 2 miles. What is the % grade?
Slope = rise/run
=25/(2 x 5280)
=0.00236
=0.00236 x 100 = 0.24%
What is the volume of a cone in cubic feet? Dimensions are 6" diameter, and 10" height?
Come volume = πr^2h/3
=π(.5/2)^2(0.83)/3
=0.054 cf.
