2.

a car travels 360 km with uniform speed.If the speed was 6 km/h less the time taken to cover the same distance would be 2 hours more.Find speed and time​

Answer»

Explanation:

let the speed of car previously be xkm/hr

the TIME TAKEN be y HRS

distance=s×t

360=X×y

360/y=x

Now,

new speed of car=x-6 km/hr

new time taken=y+2 hrs

distance=(x+6)(y+2)

=xy+2x+6y+12

A/Q

x×y=xy+2x+6y+12

0=2x+2y+12

0=2×360/y+6y+12

0=720/y+6y+12

0=720+6y^2+12y/y

After that factorize it and then put the value of y in any equation then the value of x will be found

Differentiate between sprinkler method and drip irrigation method

Answer»

Answer:

Explanation:

HEY MATE

What is the difference between drip irrigation and sprinkler irrigation?

Dripping valves are present in drip system while SPRAY guns and nozzles are used in sprinkler system. Only the root area is wetted by drip irrigation, whereas one sprinkler wets an area of a circle, which covers a number of plants.

ADVANTAGES OF DRIP IRRIGATION

This system is good for a small yard or for watering individual plants. ... The advantage of drip irrigation over sprinklers is that there is little water loss due to evaporation or runoff. It's particularly good for mulched areas because it can directly soak the soil without washing away the mulch.

DISADVANTAGES OF DRIP IRRIGATION

Plastic tubes affect soils fertility. Sun degrades plastic sometimes and that affect soil and fertilizers too. Tubes get clogged sometimes. Water cannot PASS through and roots get dehydrated.

ADVANTAGES OF DRIP IRRIGATION

There is no requirement of using many areas of your field for setting up the sprinkler irrigation.

The interference with cultivation for setting up the sprinkler irrigation is very less. So, you will not face a HUGE loss.

Frequent application of water can be supplied to the plants you will not need to do it yourself.

The water distribution will always be equal.

The amount of water being supplied can be controlled so you will be also able to save water depending on the necessity and requirements of plants.

The sprinkler irrigation is suitable for setting up in all types of soil.

This system can be used for other PURPOSES as well such as cooling during high temperature

Disadvantages of Sprinkler Irrigation System

   High initial COST.

   High operating cost.

   Wind drift.

   A stable water supply is needed.

   Saline water may cause problem.

   Water must be free from sand, debris and large amount of salt.
