Assertion : When a Rubber band is stretc...

Assertion : When a Rubber band is stretched to a particular length, there is a change in length as well as the elastic potential energy is increased i.e., `U=(1)/(2)Kx^(2)`
Reason : A bullet shot from the gun if embedded in a long of wood. Kinetic Energy is not conserved, but momentum is conserved, but momentum is conserved. The loss in kinetic is `Delta theta = K.E_(i)-K.E_(f)`

Assertion: As temperature of gas increases the KE of molecules increases, but P E. decreases. Reason: Due to law of conservation of energy.

Assertion : When Air is blow on a plastic cover, lying on the floor. If flies to a particular height in different directions. Also It's energy at different positions keep changing. Reason : Work done by the force on the body changes the kinetic energy of the body. This is called Work - Energy Theorem. i.e., W = Delta K.E.

A comet orbits the sun in a highly elliptical orbit. Does the comet have a constant (a) linear speed, (b) angular speed, (c) angular momentum, (d) kinetic energy, (e) potential energy, (f) total energy throughout its orbit? Neglect any mass loss of the comet when it comes very close to the Sun.

An object is thrown from Earth is such a way that it reaches a point at infinity with non-zero kinetic energy [K.E(r=infty)=(1)/(2)MV_(infty)^(0)] , with what velocity should the object be thrown from Earth?

Separation of Motion of a system of particles into motion of the centre of mass and motion about the centre of mass : (a) Show p=p_(i)'+m_(i)V where pi is the momentum of the ith particle (of mass m_(i) ) and p'_(i)=m_(i)v'_(i) . Note v'_(i) is the velocity of the ith particle relative to the centre of mass. Also, prove using the definition of the centre of mass sump'_(i)=O (b) Show K=K'+1//2MV^(2) where K is the total kinetic energy of the system of particles, K′ is the total kinetic energy of the system when the particle velocities are taken with respect to the centre of mass and MV^(2)//2 is the kinetic energy of the translation of the system as a whole (i.e. of the centre of mass motion of the system). The result has been used in Sec. 7.14. (c ) Show L=L'+RxxMV where L'=sumr'_(i)xxp'_(i) is the angular momentum of the system about the centre of mass with velocities taken relative to the centre of mass. Remember – r'_(i)=r_(i)-R , rest of the notation is the standard notation used in the chapter. Note ′ L and MR × V can be said to be angular momenta, respectively, about and of the centre of mass of the system of particles. (d) Show (dL')/(dt)=sumr'_(i)xx(dp')/(dt) Further, show that (dL')/(dt)=tau'_(ext) where tau'_(ext) is the sum of all external torques acting on the system about the centre of mass.

Assertion : The moment of Linear Momentum is called Angular momentum (L) i.e. L = r xx p = (mv) xx r = mvr if V = r omega then. L = mr^(2) omega (or) L = I omega Reason : For conservation of Angular momentum, Torque (Rotational force applied externally) must be zero.

The position vectors of the vertices A, B and C of a tetrahedron ABCD are hat i + hat j + hat k , hat k , hat i and hat 3i ,respectively. The altitude from vertex D to the opposite face ABC meets the median line through Aof triangle ABC at a point E. If the length of the side AD is 4 and the volume of the tetrahedron is2/2/3, find the position vectors of the point E for all its possible positfons
