The figure below shows a bar of mass m = 0.280 kg that can slide without friction on a pair of rails separated by a distance ℓ = 1.20 m and located on an inclined plane that makes an angle θ = 29.5° with respect to the ground. The resistance of the resistor is R = 1.50 Ω, and a uniform magnetic field of magnitude B = 0.500 T is directed downward, perpendicular to the ground, over the entire region through which the bar moves. With what constant speed v does the bar slide along the rails?

Two capacitors C₁ = 5.9 ?F, C₂ = 16.2 ?F are charged individually to V₁ = 15.7 V, V₂ = 4.9 V. The two capacitors are then connected together in parallel with the positive plates together and the negative plates together.
Calculate the final potential difference across the plates of the capacitors once they are connected.

Calculate the amount of charge (absolute value) that flows from one capacitor to the other when the capacitors are connected together.

By how much (absolute value) is the total stored energy reduced when the two capacitors are connected?

Answer the following:

Describe angular velocity and angular acceleration. In your own words, explain the relationship between linear and angular quantities. In your own words, explain rotational kinetic energy and moment of Inertia.

True or false for each statement :

1)Without friction or work by an external force, the sum of the potential and kinetic energies of a body is constant.

2)Work is done when the form of energy changes.

3)Work can be done in the absence of motion.

4)Less power is required while slowly lifting a box than while lifting it up quickly.

5)Energy conservation law for a projectile (no friction): Potential energy decrease equals the kinetic energy increase.

6)A source of energy is required to do work.
