The rate of decay is measured by its - correct answer- Half life
The pH number that indicates the greatest acidity is - correct answer- 1
Approximate mass of 49N weight is - correct answer- 5KG
The atomic number is the number of protons in an atom - correct
answer- Atomic nucleus
10 - correct answer- Flourine has an atomic weight of 19 and an atomic
number of 9. What is the number of neutrons in the atomic nucleus?
65 - correct answer- An atom has 30 protons and 35 neutrons in its
nucleus. It has 30 electrons in its shells. Its atomic weight would be?
Granular materials - correct answer- Backfill for use around culverts and
pipes consists of
Alignment of the pipe - correct answer- An inspector looks through one end
of a drainage pipe. He is most likely checking
,Larger trench widths mean more backfill material, which increases costs. -
correct answer- 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?
Obtain a small part of a lot to represent the whole. - correct answer-
The main purpose of sampling any material is?
Weight of water/weight of cement - correct answer- What is the water
cement ratio?
Used to separate fine grain from coarse grain. It carried out by washing
the soil specimen on a 60pm sieve mesh. - correct answer- Wet sieve
Density check - correct answer- 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?
Strength - correct answer- Slump test of concrete test all but which one of
the following? Water cement ratio, admixture content, strength,
durability/workability, water content.
3 equal layers according to volume - correct answer- For a concrete slump
test how is the cone to be filled with concrete?
, S 23° 30' E - correct answer- How is the bearing of a line notated?
Surveying tape and plumbing bob - correct answer- Horizontal distances
over sloping ground are usually determined by?
Less - correct answer- 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'?
45530-45020 = 510'
510 x 0.020 = 10.2'
1252.0 + 10.2 = 1262.2
Answer is 1262.2 - correct answer- 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?
Used to determine the subdivision of the smallest division of a scale. -
correct answer- What is the varnier on a leveling rod used for?
25 pounds - correct answer- What is the proper tension for a 100' steel tape?
Too large - correct answer- When measuring with a steel tape a sag is
detected. What will the reading be?
