1. The graphite is used in making lead of the pencils 2. Due to its slippery nature, graphite is used as a dry lubricant in machine parts.
3. Being resistant to chemicals and having .....
Here, Final SP with VAT = Rs.16720 So, SP + VAT% of SP = Rs.16720 or, SP + 10% of SP = 16720 or, 11SP/10 = 16720 or, SP = 15200 Again SP = MP - Discount % of MP or, 15200 = MP - 5% of MP or, 15200 = 95MP/100 Solve .....

Here, P = Rs.50000. For the first year, CI = P[ (1 + R/100)T - 1] = 50000[ ( 1 + 8/100 - 1)] = Rs.4000. 5 % of 4000 = Rs.200 is deducted as government tax. At the end of 1st year he will have 50000 + 4000 - 200 = Rs.53,800 in has .....
Genetics is the study of heredity. Heredity is a biological process where a parent passes certain genes onto their children or offspring. Every child inherits genes from both of their biological parents and these genes, in turn, express .....
Let the two numbers be x and y. By question, x+y = 39 ------------------ [ I ] And, x=y+5 ------------------------ [ II ] Placing the value of x from equation [ II ] to equation [ I ] , we get, x+y = 39 y+5+y = 39 2y + 5 = 39 2y .....
ii) Middle coat ( choroids) It is the middle layers of the eyes made up thin layer of connective tissues. It again consists of three parts i.e choroids, ciliary body and iris. The choroids lies in the posterior region of the sclera and .....
If you pluck those hairs, germs and particles near the follicles can get inside and cause an infection. The hair helps to block the dust and particles getting inside the lung. And cause an .....
So, equation of st.line is y - y1 = m2(x - x1) or, y - 2 = (-2-√3)(x - 1) Simplify and get answer. Similarly take -ve and get another answer. Note: This question is too long. It will not ask in .....

Let the first term be 'a' and the common ratio be 'r'. From first condition, Sum of first three terms = 7 We know, the first three terms are a , ar, ar2 So, a + ar + ar2 = 7 So, a(1 + r + r2) = .....
To find the fifth term we need frist term(a) and common ratio ( r ) So to find it we have to use given condition. From the 1st case, t3 / t6 = 1 / 8 or, a r2 / ar5 =1/8 or, r3 = 8 Find r. Again from the second .....
Since ( x2 + 3x + 2 ) is a factor, Then, x2 + 3x + 2 = 0 x2 + 2x + x + 2 = 0 x(x+2)+1(x+2)=0 (x+2)(x+1) = 0 Either, Or, x+2 = 0 .....
Here, cotB = kcot A or, 1/tanB = k/tanA or, tanA / k = tanB or, tanA / tanB = k/1 or, sinAcosB / cosAsinB = k/1 [ Changing tan into sin & cos.] or, ( sinAcosB + cosAsinB)/( sinAcosB - cosAsinB)= .....
