A ladder leaning against a wall makes an angle alpha with the horizontal ground such that tan alpha=3/4 . If the foot of the ladder is 5 m away from the wall, what is the length of the ladder? किसी दीवार पर झुकी हुई एक सीढ़ी क्षेतिज भूमि के साथ कोण alpha इस प्रकार बनाती है कि tan alpha=3/4 है| यदि सीढ़ी का तल दीवार से 5 मीटर दूर है तो सीढ़ी की लंबाई ज्ञात करें |

Is 180 a common multiple of 3, 4 and 5?

Bulbs are packed in cartons each containing 40 bulbs. Seven hundred cartons were examined for defective bulbs and the results are given in the following table : {:("Number of defective bulbs"," 0 1 2 3 4 5 6 More than 6"),("Frequency","400 180 48 41 18 8 3" " 2"):} One carton was selected at random. What is the probaility that it has (i) no defective bulbs ? (ii) defective buble from 2 to 6 ? (iii) defective bulbs less than 4 ?

The lengths of 40 leaves of a plant are measured correct to the nearest millimetre, and the data obtained is represented in the following table: Length (in mm): 118-126 127-135 136-144 145-153 154-162 163-171 172-180 No. of leaves: 3 5 9 12 5 4 2 Find the mean length of leaf.

A small coil is introduced between the poles of an electromagnet so that its axis coincides with the magnetic field direction. The cross-sectional area of the coil is equal to S = 3.0 mm^2 , the number of turns is N = 60 . When the coil turns through 180^@ about its diameter, a galvanometer connected to the coil indicates a charge q = 4.5muC flowing through it. Find the magnetic induction magnitude between the poles, provided the total resistance of the electric circuit equals R = 40 Omega .
