1. Bernoulliās principle is a statement of energy conservation in static fluids.
2. For most solids, the coefficient of volume expansion is proportional to the coefficient
of linear expansion.
3. Latent heat of a material does not affect the amount of heat transfer across a slab
by conduction.
4. If the net force acting upon a body is zero, the particle is always at rest.
5. A football kicked at an angle 0 with respect to the horizontal means that the
acceleration is 9.8m/s2 at all times.
6. Equilibrant force is the combination of all the forces acting on an object.
7. Reflection occurs when there is the presence of medium where light can travel.
8. Diverging Lenses always have negative focal length.
9. The total mechanical energy in the system must always be equal to zero.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
