Any two types of chemicals used in agriculture which causes water pollution

Excess nutrients, such as nitrogen and phosphorus, can harm soils, rivers, lochs and estuaries by causing algal blooms and by changing the natural balance of plants, insects and other life. In the wrong place, pesticides can kill river insects and fish and can remain in river sediments for many years. These chemicals include fertilizers rich in nitrogen and phosphorus, herbicides, insecticides, and fungicides. Water pollution results from runoff of these chemicals into surface waters or from infiltration of these chemicals into groundwater.

Let a be the first term and d be the comman ratio. S1 = n/2[ 2a+(n-1)d ] S2 = 2n/2[ 2a+(3n-1)d ] S3 = 3n/2[ 2a+(3n-1)d ] Now, Right Hand Side (RHS) = 3( S2- S1) = 3 { 2n/2[2a+(2n-1)d] - n/2[2a+(n-1)d]} On solving this , we get = 3{ an + 3n²d/2 -nd/2 } = 3 { n [ a + ( 3n-1)d/2 ] } = 3n/2 [ 2a + ( 3n-1) ] = S3 .

How sound waves travel in medium .

Posted by Abhishek Saini 7 years, 2 months ago

CBSE > Class 08 > Science

1 answers

Yogita Ingle 7 years, 2 months ago

Sound travels through a medium in the form of waves. When vibrations take place, they are transmitted through a medium and form alternate compression and rarefactions.
Compressions are regions in the medium where the particles are closer whereas rarefactions are regions in the medium where the particles are spread out.

Which is the best fibre?

Posted by Md Nek Tousif 7 years, 2 months ago

CBSE > Class 08 > Science

1 answers

Meghna Thapar 5 years, 6 months ago

Fibers that are soluble, viscous and fermentable seem to be the healthiest, by far. Resistant starches are also incredibly healthy. Good sources of healthy fibers include vegetables, fruits, oats, legumes, nuts, dark chocolate, avocados, chia seeds and various other foods. A lack of fiber in your diet could be making you gain fat. This is because fiber helps control your appetite to keep you fuller for longer. One study showed that eating an extra 14 grams of fiber per day may decrease your calorie intake up to 10%.

CP of 15 pens is equal to that of SP of 12 pens . Find profit percent

Posted by Aayush Mishra 7 years, 2 months ago

CBSE > Class 08 > Mathematics

1 answers

Yogita Ingle 7 years, 2 months ago

Let the CP of each pen be Rs.x.

Then,

CP of 12 pens = Rs.12

SP of 12 pens=CP of 15 pens = Rs.15

now ,gain = SP- CP=Rs.(15 - 12) = Rs.3

gain%=gain/cp × 100

=(3/12 × 100)% = 25%

Hence, the gain = 25%.
