7. False

8. False

9. True

(i) What is Rabat and where is it attached? 

(ii) What is used to run it? 

(iii) In what work is the Rahat used

The electric motors.

(i) A Rahat is a wheel-like structure installed over the shallow wells or stepwells. 

(ii) Many vessels of w ater are attached over it Wlien they enter the water inside the well, the vessels get filled with water. 

(iii) Oxen are used to operate the Rahat. 

(iv) When the vessels come out from the well, they move from upwards to downwards directions, the wheel rotates and the water continuously falls on the parapet of the w ell. 

(v) From here, the w’ater flows through the drains and reaches the farms and helps in irrigation.

Irrigation is necessary for crop production True.

(d) All of the above

The different methods of irrigation are—tubewells. motor set. pump set. rahat, fountains, wells, canals, bawadis etc.

Peas, gram, onion, cucumber require ess amount of water.

(i) Peas 

(ii) Gram 

(iii) Onion 

(iv) Cucumber

In our nearby fields the irrigation facilities of fountain, motor, rahat, pipelines etc. are used

Sugarcane and paddy.

No, the requirement of water for every crop is different.

For sugarcane and paddy, farms are required to remain completely filled with water.

Motors and hand pumps have been used to extract water from the grounds.

We have seen the flowing water in canals, springs, drains, rivers etc.

If the water level in the well goes down, the level of water should be made equal to the rahat level. After that the water can be taken out by rahat. Else it is not possible.

The water for agriculture is available from canals, rivers, ponds, water of rainfall etc.

Ground water level is the main source of water of the well is True.

Motor is regulated by electricity True.

With the help of ropes and buckets, the water is taken out from the wells. Nowadays,rahat and motor pumps are also used for taking out the water from the

Onion crops requires less amount of water.

Excessive rainfall destroys crops and the scarcity of rainfall creates drought.

(c) In parapet

The water flows from upward to downward direction. This water is used for drinking purpose, generating hydro-electricity and increasing the facility of irrigation.

For this we can supply water by fountain process

Water always flows from downwards to upwards is False.

The water flows from upward to downward direction.

Flowing water is being used in generating hydro-electricitv and provide facilities of irrigation.

In RAHAT irrigation, the animal labour has been used.

The water which comes through the tube wells, flows to the crops in the field.

Oxen are used to oprate the rahat.

Rahat is installed over the shallow wells or step wells.

1. (oxen). 

2. (drains). 

3. (rahat). 

4. (drains).

In motor and pumpset irrigation, electricity is being used.

A rahat is a wheel like structure installed over shallow wells or stepwells. Many vessels of water are attached over here. When the vessels come out from the well, they move from upward to downward direction and the water continuously falls on the parapet of the well. The water of rahat flows to the drains and reaches the farms.Oxen are used to operate the rahat. Nowadays, the electric motors are more frequently used due to which the use of oxen is reduced.

The requirement of water for every crop is different. Some crops need more water and some need a lesser amount. In this way, wastage of w’ater can be prevented. The crops of rice, sugarcane and paddy require more water, whereas the crops of peas, gram, onion, cucumber require less amount of w ater. If a farmer has a good knowledge about it. then water can be used properly.

(i) How is the water from the tubewell removed? 

(ii) How to use tubewells for irrigation? 

(iii) From where the water is removed from the tubewell?

The equation of state for an adiabatic process is given by

PV^y = Constant

Here γ is called adibatic exponent

(γ = C_p /C_γ ) which depends on the nature of the gas

(a) PV = (5/32) RT

Number of moles, n = \(\frac{5}{32}\)

(b) it will bend towards the left

In cold bath, the metal X will contract more than the metal Y. Therefore, the strip will bend towards the left.
