Q
If not then the loss in kinetic energy is transferred into which form of energy??
No, the kinetic energy is not conserved in case of inelastic collision. The loss in kinetic energy is transferred in various other form of energy like sound energy, heat energy, light energy etc.
Which of the species is more stable O or N? Nitrogen is more stable than Oxygen due to half-filled electrons in Nitrogen.

A massless rope is fixed at one end as shown in fig. Two boys of masses 40kg and 60kg are moving along the rope. The former climbing up with an accelaration of 2m/s^2 while  later coming down with constant velocity of 5m/s. The tension at fixed support will be (g=10m/s^2)

Nucleophilicity is highest in polar aprotic solvents, and lower in polar protic solvents because polar protic solvents (like water) can make H-bond and it will ultimately make the nucleophile more bulky. E.g. of polar protic solvents - H2O, CH3OH, CH3CH2OH, CH3COOH, H2SO4 E.g. of polar protic solvents - DMSO, Acetone, DMF, HMPA, Acetonitrile  If the solvent is polar aprotic, it’s safe to assume...

Time (T), velocity (C) and angular momentum (h) are chosen as fundamental quantities instead of mass, length and time. In terms of these, the dimensions of mass would be :

Dimension of length

Q. What is the difference between molarity and normality?

iska answer kya hai 

A man of mass (m_A) is sitting in a train movingwith velocity v_1 = 3 m/s . He observe that a block of mass m_B is moving towards him with velocity v_2 = 5 m/s. Then the kinetic energy of block w.r.t  man is (Assume m _B= 5 Kg)

 K.E of the block from the reference frame of the train is 

A block of mass m is kept on a platform which starts from rest with constant acceleration g/2 upward, as shown in the figure. Work done by normal reaction on block in time t is:

By balancing the forces in vertical direction, we get: and displacement is given by equation: where u=0 and a=g/2 and we know,

When the rms voltages VL, VC and VR are  measured respectively across the inductor L, the capacitor C and the resistor R in a series  LCR  circuit  connected  to  an AC source, it is found that the ratio VL : VC : VR = 1 : 2 : 3. If the rms voltage of the AC source is 100 V, then VR is close to ?
