The energy due to configuration or shape of an object is called its potential energy. An example where potential energy is in large amount is, "Suppose a very large spring is compressed and hooked. Then at that time it has large amount of energy which is potential energy."
Mitosis, development, regeneration and cell differentiation Mitosis is a type of cell division
Frictional force always acts opposite to the motion this is right so option A
Angle of Banking - a vehicle can go round the curved road at a reasonable speed without skidding, the sufficient centripetal force is generated by raising the outer edge of the road a little above the inner edge. so option c is correct
V = root( g * r * f ). = Root ( 10 * 400 * 0.1 ) = 20 m/s option A
centripetal force maximum at equator
centrifugal force is called fictitious force
statement - Railway tracks are banked at the curves so that the necessary centripetal force may be obtained from the horizontal component of the reaction on the train. is true so option A is correct
Centripetal force always acts at 90 degrees to the velocity, and away from the centre of the circle. this statement is false bcz it acts towards center.

Given - n=24, PMT = 4000 and FV = 106000 Now for Annuity FV = C*/i * ((1+i)^n - 1)​, putting all values we found 10% so answer (C)
Given , Total no of cards= 52 No of Aces = 4 P(ace) = 4/52 = 1/13. 2) P(not red) = 1 - P (red) Total no of cards =52 No of red cards = 26 P(not red)= 1 - (26/52) = 1 - (1/2) = 1/2
M = R [ (1+i)n – 1] ——————– 1- (1+i) -1/3 Where, M = Maturity value R = Monthly Installment r = Rate of Interest (i) / 400 (Annual interest rate converted into quarterly rate) n = Number of Quarters (Assuming the compounding is done quarterly) we get M= Rs21,244.00 Hence Option C is the closest to the correct answer
Total value of share = 200 x 15 = Rs 3000 Total dividend received = Rs 300 So rate of dividend = (300/3000) x 100 = 10%
2*pi*(r^2 + 8*r) = 528 . By solving, R = 6 cm [pi = 22/7] Again let, the no. spheres be n . ATP, n.(4/3).*pi*2^3 = pi*6^2*8 . By solving, n = 27
Given- PT * TQ = ST*TR Also by Pythagorean theorem , TS = root of 6^2 -5^2 = rt 11 hence 4(5) = rt 11 (TR) TR = 6.03 cm
Distance between vertices= Distance between (8,3) and (14,3) = 6 units
in triangle MRQ, Tan 60 = MR/QR, QR = MR Tan 60 , similarly PR = MR , IN TRiangle PQR , PR Cos 50 + QR Cos60 = 500 So option B is right
In Δ POQ, tanx = h/b and in Δ POR tany = h/(b+a) Therefore h= btanx...(i) and h= (a+b)tany ...(ii) Equating (i) and (ii) we get btanx = (a+b)tany ⇒ btanx = atany + btany ⇒ btanx - btany = atany ⇒ atany = b(tanx - tany) ⇒ b= atany/(tanx-tany) putting the value of b in (i) we get height of the building, h= tanxtany(tanx-tany)
given the values , put in equation , H = (a-b)/|cot60 - cot30| H = (a-b)/ |√3 - 1/√3| H= (a-b)*√3/2
by trignometric equn we found and put in equation , Tan 60° = x/6 (perpendicular/base =tan x) √3 =x/6 (tan60° =√3) Or, x = 6√3 cm And, cos 60° = 6/y 1/2 = 6/y Or, y =6×2 =12 cm So, the total height of tree is x+y =( 6√3+12)cm
One half is bent in the shape of square i.e. perimeter of square = L/2 units. Let each side of square be A units. Then as per question, 4A=L/2 =>A=L/8 Area of square=A²=L²/64 sq.units; Now,the other half of wire is bent into sector, Length of sector,S =L/2 Let R be radius of the sector Converting 120 degrees into radians=(π/360)*120=π/3 radians Therefore ,Length of sector,S=R*π/3 units =>R=3S/π, =>R=3L/2π Area of sector=1/2 R²Φ=1/2* length of arc *radius; where Φ is in radians =>Area of sector=1/2 R²Φ=1/2*(9L²/4π²)*π/3 sq.unit Area of sector=3L²/8π sq.unit Area of square:Area of sector=L²/64:3L²/8π=11/84 sq.units
the cylinder is completely hollow and open on both sides, the curved(lateral) surface area CSA = 2πrh( r=radius of the cylinder and h=15 cm,height of the cylinder) 2πrh = 2500(given) => r = 2500/2πh Volume of the cylinder = πr^2h = π*15 *(2500/2πh)^2 = 25*25*10^4/(4*15π) = 3.315727 X 10^4 = 33157.2 cm3 Hence option A
given , area of cylinder / 2 = pi * r * l = 3.14*5*40 = 628 area of one wall * 2 = 7*40*2 = 560 total area = 1188 cost of painting = 5*1188 = Rs 5940/-
A=amount, P= principal, r= rate of interest in decimal, n= number of times interest compounded per year, t= time in years, A = P(1+r/n)^nt , A = 36000(1+0.16/2)^2*3/2 = 36000 (1.08)^3 = 36000*1.25972 = 45,349.63 Therefore, interest = Rs. A - P = 45,349.63 - 36000= Rs. 9,349.63
20/(20+10+30+10) = 20/70 =2/7; (ii) (20+30+10)/(20+10+30+10) = 60/70 = 6/7
price = 5000 After getting discount of 20% = price he pays to buy = 5000*80 % =4000 Sales tax charged = 5% so total price he pays to buy good = 4000*5/100 =200 Collected tax = 7% so total chaged from customer = 5000*7/100 = 350 So VAT = 350-200 = 150
height of the tower be x m and the separation distance between the cliff and the ower be y m So tan 45 = 1 = 80/y. This gives y = 80 m Also tan 30 = 0.577 = (80-x)/y = (80-x)/80 . This gives x = 33.84 m
original hollow cylinder = 22/7 x 5 x (10 x 10 - 8 x 8)= 22/7 x 5 x 36 cubic cm.....(1) Volume of one cone = 1/3 x 22/7 x 3 x 3 x 5 = 22/7 x 5 x 3 cubic cm.......(2) Dividing (1) by (2) we get the number of cones = 36/3 = 12
Let the number of children be x So [(6800/x) - (6800(/(x +9)] = 153 This gives x(x+9) = 400 Or soving the quadratic equatuib x = 16
the speed of cars A and B is 7x and 5x respectively, if peed of both the cars is reduced by 2 km/hr, then ratio becomes 3 : 2, So, (7x-2) / (5x -2 ) = 3/2; 15x - 6 = 14 x - 4 => 15x - 14x = 6 - 4 =2; therefore, the speed of cars A and B is 14 and 10 km/hr respectively
numerator=x So,denominator=x+5 A/c to question x+5/x+3=5/13 =>13x+65=5x+15 =>8x=50 X=50/8 =25/4 So put fraction=x/x+5

The Hindi–Urdu controversy is an ongoing dispute—dating back to the 19th century—regarding the status of Hindi and Urdu as a single language. Hindi is a literary register of the Hindustani language, derived from the Khariboli dialect of the Hindi languages. A Persianized variant of Hindustani began to take shape during the Delhi Sultanate (1206–1526 AD) and Mughal Empire (1526–1858 AD) in South Asia

(Da/Db) = (Sa/Sb) i.e. (Da/Db) = 16/21. Let Da = 16k and Db = 21k. Given that one train travelled 60 km more than the other. Hence, 21k - 16k = 60 i.e. 5k = 60. Therefore, k = 12. Total distance between the two stations is nothing but the distances travelled by the respective trains till the meeting point i.e. (16k + 21k) = 37k = 37 * 12 = 444 km. Hence, option (B) [ - ]
stoppage the bus travels (45-36) = 9 kms less. Time taken for traveling 9 kms = 9/45*60= 12 mins hence the stoppage is 12 mins Option B
The marked price of a laptop is $1050. If it is sold at a discount of 10% yielding a profit of 25% Marked Price of the laptop(M.P) = $1050 Discount(D) = 10% Profit(P) = 25% Now, Price after 10% discount = 1050 – 10*1050/100 = 1050 – 105 = 945 (dollar) So selling price (S.P) = $945 After giving discount profit is 25% Now, P = (S.P – C.P)*100/C.P (C.P = cost price) Cross multiplying, Or, 25 * C.P = 100*S.P –100* C.P Or, 125*C.P = 100*945 Or, C.P = 94500/125 = 756 Therefore the cost price of the laptop was $756
x=8y Eight years from now, (x+8)/(y+8)= 10/3 => 3x+24 =10y+80 => 24y+24= 10y+80 => y=4 . Therefore, x = 8*4=32 Reena's present age is 32 years

perfect squares between 200 and 330 like 225 and 256. By definition, rational numbers are p/q, where q= not equal to zero. Now the rational numbers r1= √225/100= 15/10 = 1.5 and r5 = √256/100 = 16/10 =1.6 so we have found two rational numbers . Let the other rational numbers be r2, r3.......r8 . So r2= (1.5 +1.6)/2 = 1.55 = 155/100 r3 = (1.5 + 1.55)/2 = 1.525 =1525/1000 Therefore, r1= 15/10, r2= 155/100. r3= 1525/1000, r5= 16/10 If we continue like this, we can easily find 10 ratioanl numbers between √2 and √3 [ - ]
6^n always end with 6 for any natural number n, so it is never ends with 0.
HCF of (33 - 3) = 30, (55 - 5) = 50 and (64 - 4) = 60 . HCF of 30, 50, 60 = 10 .
a = bq + r (1) 38220= 196* 195 + 0 (2) 867= 255*3 +102 255=102*2 + 51 102= 51*2 + 0 51 is our HCF (3) 225= 135*1 + 90 135= 90*1 + 45 90= 45*2 +0 45 is our HCF So, 196 is our HCF
the LCM of 18 and 12. LCM(18, 12) = 36 So after 36 minutes
LCM * HCF = product of the given two numbers LCM = ( 306*657) / 9 = 22338
