Question

Part II. True or False 1. Bernoulli’s 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. 10. Electric field is the strongest when it is close to the charged particle creating the field.

    Answer:

    True 1, 2,3, 6, 8 and 10

    False 4, 5, 7 and 9

    Explanation:

    In this exercise, several situations will be analyzed, to know if they are true/false

    1) True. Bernoulli’s equation is the conservation of energy

    2) True. The volumetric expansion is approximately 4 times the linear expansion

    3) True. Latent heat is the heat used in a phase transformation and does not change the temperature of the body and the conduction is proportional to the change in temperature.

    4) False. The particle can be at rest or at constant velocity

    5) False. Acceleration depends on the force of the kick

    6) True. The sum of force must be zero

    7) False. Reflection occurs at the interface between two different media

    8) True. Diverging lenses the focal length is negative

    9) False. Manganic energy is the sum of the energies, therefore it must be different from zero

    10) True. The electric field is inversely propositional to the square of the distance
