For a vehicle to make safe turning on the curved road, the outer edge of the road is raised little above the inner edge making some inclination with the horizontal. This is known as Banking of Road. Purpose of Banking :

Answer 4 people found it helpful rishavtoppo We need to derive the formula for kinetic energy of a particle using dimensional analysis. Solution : Let m is the mass and v is the velocity of the object. Let kinetic energy of the particle is km^xv^y The dimensional formula of mass, [m]= [M] The dimensional formula of velocity, [v]= [LT⁻¹]

Advertisement Expert-Verified Answer 445 people found it helpful prmkulk1978 Kinetic energy is the energy possessed by an object by virtue of its motion. K.E=1/2 mV² Derivation: Let us consider an object of m which is at rest lying on a table. Let A force F acts on the object which moves the object through a distance S. The workdone=FxS

Decrease in freezing point of a solution prepared by dissolving one gram molar mass of non - volatile solute into one kilogram of solvent is called molal depresion constant. Let T(f)^(0) be the freezing point of pure solvent and T(f) be its freezing point when non - volatile solute is dissolved in it. The decrease in freezing point. Delta T(f)=T(f)^(0)-T(f) is known as depression in freezing.

To get the pH and pOH correlation, we take a negative log of both sides of the equation: -log [H +] + (- log [OH – ]) = – log 10 -14 Notice that the terms on the left represent the pH and pOH of the solution (-log [H +] = pH, – log [OH –] = pOH). Therefore, we can write that: pH + pOH = 14

where r is the perpendicular distance from the axis of the rotation and f is the applied force. For rotational motion torque is given by: τ = Iα ----- 1. 1. where I is the moment of inertia of the body about an axis of rotation. α. α is the angular acceleration. We know for the rotational body angular momentum is conseverd.
