At noon, the rays of sunlight have to travel comparitively lesser distance while passing through the earth's atmosphere and fall normal to the earth's surface. This causes the blue and violet lights to get scattered in a less intense manner along with the red lights. Thus, sun appears white at noon. But, at other instances, the distance increases increasing amount of scattering of blue and violet lights causing lights of longer wavelengths to reach our eyes. So, sun appears white ONLY at noon.

Preeti Dabral 4 years, 3 months ago

Given, height of object = 5cm

Position of object, u = - 25cm

Focal length of the lens, f = 10 cm

Hence, position of image, v =?

We know that,

1/v - 1/u = 1/f

1/v + 1/25 = 1/10

So, 1/v = 1/10 - 1/25

S0, 1/v = (5 - 2)/50

That is, 1/v = 3/50

So, v= 50/3 = 16.66 cm

Thus, distance of image is 16.66 cm on the opposite side of lens.

Now, magnification = v/u

That is, m = 16.66/-25 = -0.66

Also, m= height of image/height of object

Or, -0.66 = height of image / 5 cm

Therefore, height of image = -3.3 cm

The negative sign of height of image shows that an inverted image is formed.

Thus, position of image = At 16.66 cm on opposite side of lens

Size of image = - 3.3 cm at the opposite side of lens

Nature of image – Real and inverted....

11x + 15y = -23 ---- (1) ////// 7x - 2y = 20 ---- (2). Take equation (2). Thus, x = 20 + 2y / 7// ---- (A). Equating (A) to (1), we get :- 11 (20 + 2y / 7) + 15y = -23 => 220 + 22y / 7 + 15y = -23 => 220 + 22y + 105y = -161 => 127y = -161 - 220 => 127y = -381 => y = -3// Therefore, x = 20 + 2y / 7 = 20 - 6 / 7 = 14 / 7 = 2//

Use euclid s algorithm to find the HCF of 4052 and 12576

Posted by Snowie Bakshi 4 years, 3 months ago

CBSE > Class 10 > Mathematics

1 answers

Preeti Dabral 4 years, 3 months ago

According to Euclid’s Division Lemma if we have two positive integers a and b, then there exist unique integers q and r which satisfies the condition a = bq + r where 0 ≤ r ≤ b.

HCF is the largest number which exactly divides two or more positive integers.

Since 12576 > 4052

12576 = (4052 × 3) + 420

420 is a reminder which is not equal to zero (420 ≠ 0).

4052 = (420 × 9) + 272

271 is a reminder which is not equal to zero (272 ≠ 0).

Now consider the new divisor 272 and the new remainder 148.

272 = (148 × 1) + 124

Now consider the new divisor 148 and the new remainder 124.

148 = (124 × 1) + 24

Now consider the new divisor 124 and the new remainder 24.

124 = (24 × 5) + 4

Now consider the new divisor 24 and the new remainder 4.

24 = (4 × 6) + 0

Reminder = 0

Divisor = 4

HCF of 12576 and 4052 = 4.

Adithya Dev A 4 years, 5 months ago

Through the poem "Fire & Ice", the poet Robert Frost wishes to convey the message that there are very few violent passions in the world which can cause the harshest destruction the whole of earth would have ever faced. These violent passions which include human desire and hatred are capable of washing the whole of mankind itself off the earth and if we don't keep an eye or a control over these forces, then the extent of destruction we face in future would be unimaginable. Therefore, we must restrain our desires and learn to love our fellow beings.
