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 ...

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 ...

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.

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