Transverse waves - In these types of waves, the particles of the medium vibrate in a direction perpendicular to the direction of propagation of the wave. e.g.wave produced in a long string when one end is fixed.
6+( 5 - 4 + 2 ) =6+(1+2)=6+3=9
To find the ratio first we have to convert to the same units 2l = 2 x 1000 ml = 2000 ml So the ratio is 100/2000 = 1/20
sin 20 = cos 70 since sin x = cos (90-x) Also sec 70=1/cos70 using above results
length=20cm breadth = 40cm area of rectangle= length x breadth=20 x 40 = 800 cm2
five lakh eighty-two thousand and thirty
we have multiplied with 1.6 x 10-19 because it is the value of e and 106 is the value of megavolt to volt.
Total charge on sphere:
Three 5 ohm resistance are in series, which is parallel to 10 ohm The equivalent resistance is  R= (15 x 10) / 25 = 6 Ohm
No. of tents = 1500  radius = 2.8 m  height of cylindrical part = H = 3.5 m height of conical part = h = 2.1 m  now , slant height of conical part = l =  surface area of tent = CSA of conical part + CSA of cylindrical part  The surface area of tent = 92.4m2 The surface area of 1500 tents = 1500 * 92.4m2  = 138600 m2 Cost of 1m2  canvas = Rs 120  costs of 138600 m2 canvas = 120 * 138600  costa...

7+3C =14C 11C =7
Bucket in the shape of frustum  Height = h = 20 cm  Radius = R = 36 cm   radius = r = 21 cm  Area covered with aluminum  sheet for 10 buckets = CSA of a frustum of cone + area of the bottom  therefore the TSA of 10 buckets are =  cost of aluminum  sheet for   is  The total cost of the aluminium sheet is rupees 24621
Given :                                                                                     If the milkman sells half the milk at less rate to the economically weaker section of the society, he shows the values of helpful, compassion, kindness and good human being.
The rate of flow of charge is current. Its SI unit is Ampere.  Current I =dq/dt
X coordinate of both the points is zero. So the distance in Y-axis is 10 cm
Given height of frustrum, h= 16 cm upper end radius, R = 20 cm Lower end radius, r = 8 cm slant height frustrum = l Volume of milk = volume of the frustum Vol of milk Cost of 1 litre milk = 50 Rs Cost of 10.4 litre milk = Rs                                    Rupees Surface are of frustum                                                                          ...
