Water & salts are regulated by kidneys .

Direct control of water excretion in the kidneys is exercised by vasopressin, or anti-diuretic hormone (ADH), a peptide hormone secreted by the hypothalamus.

If the radius of a circle is increased by 100%, then its area is increased by

- a)100%
- b)300%
- c)200%
- d)400%

Correct answer is option 'B'. Can you explain this answer?

Saxena Aastha answered • 17 hours ago

Let, radius of circle =r and area =A

We know that,

A1=πR^2

ACC. to question radius increased by 100 percent.Then area ,

A 2 =π(r+r) ^2

=π(2r) ^2

A2 =4π.r ^2

Now area increased by

A2-A1=4π.r ^2-π.r ^2

= 3π.r ^2

so percentage increase = 3π.r ^2*100/π.r ^2

= 300

therefor answer is B

If a, b, c are in A.P. then the straight line ax + by + c = 0 will always pass through a fixed point whose

co-ordinates are :

- a)(1, – 2)
- b)(– 1, 2)
- c)(1, 2)
- d)(– 1, – 2)

Correct answer is option 'A'. Can you explain this answer?

Izumi answered • 18 hours ago

Option A is correct

Because a, b, c are in AP, therefore 2b = a + c. Putting the value of b in ax + by + c= 0, we get

ax+a+c/2(y) +c=0

or, a(2x+y)+c(y+2)=0

or, (2x+y)+[c/a](y+2)=0

This equation represents a family of straight lines passing through the intersection of 2x + y = 0 and and y + 2 =0, i.e. (1, -2).

Because a, b, c are in AP, therefore 2b = a + c. Putting the value of b in ax + by + c= 0, we get

2.Also known as Omnibus group.

3.Porous, friable structure.

4.Absence of lime, kankar (impure calcium carbonate).

5.Deficient in: lime, phosphate, manganese, nitrogen, humus, and potash.
