20) Which District Of Odisha Is The Largest Producer Of Rice - Bargarh 

PHYSICS - 

21) The Presence Of Magnetic Field At a Point Can Be Detected By - a Compass Needle 

22) Which Of The Following Is Not a Example Of a Bio Mass Energy Source - Nuclear Energy 

23) A Train Starting From Rest Attains a Velocity Of 72 kmph In 5 Minutes. Assuming That The Acceleration Is Uniform, Find Out The Distance Travelled By The Train For Attaining This Velocity - 

The Initial Velocity Of Train U - 0 

Final Velocity V - 72KMPH 

72 X 5/18 = 20 m/s 

Time Taken t = 5 Minutes = 300 Seconds 

Let A Is Acceleration And S Is Distance Covered 

V = U + at 

S = ut + 1/2 at^2 

V = U + AT 

20 = 0 +  a X 300 

300a = 20

a = 20/300 

a = 1/15 ms^-2 

S = ut + 1/2 at ^2 

S = 0 X T + 1/1 X 1/15 (300)^2 

S = 3000 m 

S = 3KM 

24) An Object Of Mass 100 kg Is Accelerated Uniformly From a Velocity 4 ms^-1 To 8 ms^-1 in 8 Seconds. Find The Magnitude Of The Force Exerted On The Object - 

Initial velocity of the object, u = 5 m/s
Final velocity of the object, v = 8 m/s
Mass of the object, m = 100 kg
Time take by the object to accelerate, t = 6 s
Initial momentum $=\mu =100\times 5=500kgm{s}^{-1}$
Final momentum $=mv=100\times 8=800kgm{s}^{-1}$
Force exerted on the object,$F=(mv-\text{mu})/\left(t\right)$
$=m(v-u)/\left(t\right)$
$=(800-500)$
$=\left(300\right)/\left(6\right)$
=50 N
Initial momentum of the object is 500 kg $m{s}^{-1}$
Final momentum of the object is 800 kg $m{s}^{-1}$. Force exerted on the object is 50 N.

6) The Only Products Of Neutralization Reaction Are - Salt And Water 

7) On Adding Water To Sodium The Solution Formed Is - Alkaline 

8) Which Is Not a Green House Gas - 

9) What Is The Mass Of 2 Moles Of Water Molecules - 32gm 

10) What Is The Change Of Gaseous State Directly To Solid State Without Going Through The Liquid State And Vice Versa - Freezing 

11) The Force Of Attraction Between Same Molecules Is Called As - Cohesive Force 

12) Metal Which Exists In Liquid State At Room Temperature Is - Mercury 

13) Which Of The Following Materials Falls Into The Category Of a Pure Substance - Iron 

14) The Formula Of Ferric Sulphate Is - Fe2 SO4)3 

15) Isotopes Of An Elements Have -
