Questions and Answers
  • 1. 

    An unstretched elastic cord of length 15.0 cm stretches by 4.0 cm when a weight of 6.0 N is suspended from it. The cord does not exceed the limit of proportionality. What is the total length of the cord when the weight is 3.0 N?

    • A.

      2.0 cm 

    • B.

      7.5 cm

    • C.

       9.5 cm 

    • D.

      17.0 cm

    Correct Answer
    D. 17.0 cm
    Explanation
    When a weight of 6.0 N is suspended from the unstretched elastic cord, it stretches by 4.0 cm. This means that for every 1.0 cm of stretch, there is a force of 1.5 N acting on the cord (6.0 N / 4.0 cm = 1.5 N/cm).

    If the weight is reduced to 3.0 N, the force acting on the cord will also be reduced by half to 1.5 N. Therefore, the cord will stretch by 1.0 cm (1.5 N / 1.5 N/cm = 1.0 cm).

    Since the original length of the cord is 15.0 cm and it stretches by 1.0 cm, the total length of the cord when the weight is 3.0 N will be 15.0 cm + 1.0 cm = 16.0 cm.

    However, the options provided do not include 16.0 cm, so the closest option is 17.0 cm. Therefore, the correct answer is 17.0 cm.

    Which object behaves as an elastic solid as it deforms?  A). A bullet as it hits a solid metal wall B). A car damaged in a collision C). A piece of metal cut by a saw D). A football as it is kicked

      C

    • D.

      D

    Correct Answer
    D. D
    Explanation
    A football behaves as an elastic solid as it deforms. When a football is kicked, it undergoes deformation due to the force applied to it. However, once the force is removed, the football returns to its original shape. This behavior is characteristic of elastic solids, which can deform under stress but regain their original shape when the stress is released.
