Physics
A stationary bomb of 10kg mass explodes into 3 fragments. two of these parts having mass 4kg and 2kg,fly apart perpendicular to each other with a velocity of 2ms-1 and 3ms-1.find magnitude and direction of 3rd part.

Physics
A ball of 0.5kg mass hits a wall at an angle of 30° and is then reflected making an angle of 90° with its original direction. if the duration of contact between the ball and the wall is 0.1s,calculate the force exerted on the wall. the initial and final velocities of b...

If sec(x+y),sec(x),sec(x-y) are in A.P. then prove that cosx= +-√2 cos y/2 where cosx and cosy are not equals to 1,

physics
A cylindrical rod( length L, radius R and density d) is dipped vertically in to a liquid. the rod is connected by a wire to a balance that measures the force to lift the rod. the contact angle between rod and liquid is θ. If rod is partially immersed so 0.5L is above the ...

science
thermo dynamic variables which are not path depends are called independent variables. for example- pressure, temperature, volume, number of moles are independent variables. Only work and energy is dependent variables. they are path dependent.

Physics
flow rate in narrow tube is 16times less than in wide tube. speed in narrow tube will be 4time smaller than wide tube

Physics
I know that way. But what is the difference in mole fraction of drugs and solvent (water) at different temp?

Physics
Drug has heat of melting 25 K jule/mole. Solubility of drug in water is 0.00082 M at 25 C and 0.00144M at 35 C. Find mole fractions x1 and x2 at each temperature.
