nucleus
10 - (answers)Flourine has an atomic weight of 19 and an atomic number of 9.
What is the number of neutrons in the atomic nucleus?
65 - (answers)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 - (answers)Backfill for use around culverts and pipes consists
of
Alignment of the pipe - (answers)An inspector looks through one end of a
drainage pipe. He is most likely checking
, 2
Larger trench widths mean more backfill material, which increases costs. -
(answers)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. - (answers)The main purpose
of sampling any material is?
Weight of water/weight of cement - (answers)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. - (answers)Wet sieve
Density check - (answers)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 - (answers)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 - (answers)For a concrete slump test how is
the cone to be filled with concrete?

, 3
Surveying tape and plumbing bob - (answers)Horizontal distances over sloping
ground are usually determined by?
Less - (answers)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 - (answers)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?

Too large - (answers)When measuring with a steel tape a sag is detected. What
will the reading be?
Multiply the size by 1/8"
6 x 1/8 = 0.75"
