(b) Carbonates
(c) Nitrates
(d) Sulphates

Q6. If the rocks are formed due to alteration of original structure under heat and excessive pressure, then they are known as _________.
(a) Igneous
(b) Sedimentary
(c) Volcanic
(d) Metamorphic

Solutions

S1. Ans.(c)
Sol. Furrow irrigation method of growing crop on running on the sides of water ditches used in certain agricultural field. furrow is very long narrow channel which carries water along the field.

S2. Ans.(b)
Sol. Table of bond stress in IS code given for plain bars in tension.
→ for HYSD bar in tension increase the value by 60%
→ for bars in compression the value is increased by 25%

S3. Ans.(d)
Sol. Minimum pitch = 2.5d
Maximum pitch =
1.Tension = (16t,200)_(min.)
2.Compression = (12t,200)_(min.)
3.For tacking rivets are provided in line = (32t,300)_(min.)
4.Plates are exposed to weather = (16t,200)_(min.)

S4. Ans.(d)
Sol. Generally, the brick work is measured in terms of m³. but in case of honey comb brick work, brick flat soling, half brick wall or partition wall then, it is measured in m².

S5. Ans.(b)
Sol. Hardness of water is due to the presence of multivalent cation.
Major ion → Ca^(+2),Mg^(+2)
Minor ion → Al^(+3),Sr^(+2),Mn^(+2),Fe^(+2)

S6. Ans.(d)
Sol. Metamorphic rocks are formed by the change in character of the original rocks when subjected to great heat and pressure.
