The formula for length contraction gives the length of an interval on a ruler moving with velocity v relative to an observer as where L is the length of the same interval on a ruler at rest with respect to the observer. By what fraction is the length of a meter stick reduced if its velocity relative to you is measured to be 87 percent of the speed of light?

Solutions

Expert Solution

The formula for the length contraction is given by

Where c is speed of light, v is speed of object with respect to the observer. L is contracted length of object and L0 is proper length of object.

For the given problem,

v = 0.87c

Therefore,

or,

If the velocity of the object is 87 percent of speed of light then the length of the meter stick will be 49 percent of its proper length.

A steel ruler (100 mm) is used for measuring the length of a block. The ambient temperature is found likely to vary in between 24 °C and 25 °C. The temperature is likely to be anywhere within these limits. The temperature variation follows square distribution, with expected value to be 24.5 °C. Determine the degree of uncertainty that will be registered when measurement is done using steel scale? CTE = 11.5 x 10-6 / °C

A muscle is undergoing a contraction at a length corresponding to 1.3 L0. If you assume that the contraction is isometric, what is the relative force the muscle is likely to be producing? If the muscle is actually producing 0.65 F0, predict whether the muscle is actually isometric or whether it is shortening or lengthening. In order to gain full credit, you need to show your work, including a listing of (1) the governing equations, (2) all parameters and variables,...

Explain the molecular regulation and mechanism of muscle contraction. Start with an action potential moving down a T-tubule and end with relaxation following a contraction. Your answer should include details of specific cellular features, molecules, ions, and their interactions to the extent that we covered it in class. Assume that we understand the basic structure of a sarcomere so that you don’t have to describe the overall structure in your response.
