Explanation Let the frame of the meterstick moving relative to you be the unprimed frame ( S ) and the meterstick at rest be the primed frame ( S ′ ). The length of a meterstick is at rest is the proper length, l 0 = 1 m and the length of the moving meterstick is l = 0.3048 m . Write the formula of length contraction l = l 0 1 − u 2 c 2 (I) Where, l is the length measured in S , l 0 is the proper length in S ′ , u is the velocity of the S frame and c is the speed of light ( c = 3 × 10 8 m / s ). Conclusion: Rearrange equation (I) to find the value of u . Squaring on both sides 1 − u 2 c 2 = l 2 l 0 2 u 2 c 2 = 1 − l 2 l 0 2 Taking square root on both sides

According to classical physics, time flow is the same for every observer. But according to einstein's theory, time flow is different for different observers. The idea that time flow is not the same for all may sound strange because we may not experience …

Hi! I need help with these calculations for part i and part k for a physics Diffraction Lab. We used a slit width 0.4 mm to measure our pattern.

Examine the data and % error values in Data Table 3 where the angular displacement of the simple pendulum decreased but the mass of the pendulum bob and the length of the pendulum remained constant. Describe whether or not your data shows that the period of the pendulum depends on the angular displacement of the pendulum bob, to within a reasonable percent error.

In addition to the anyalysis of the graph, show mathematically that the slope of that line is 2π/√g . Using the slope of your line calculate the value of g and compare it to 9.8.
