- An experiment is performed in an ideal condition to find out the velocity of a particle obeying the equation S=vtS=vt where the distance travelled (S)(S) inside a labeled glass tube by a particle with an uniform velocity (v)(v) is measured with respect to time taken (t)(t). The data collected by repeating the experiment five times is shown in the table below If we use the method to minimize the squared sum error, what is the most likely velocity of the particle among the given options? 2.5 1.5 2 1Consider a box of mass 8.5 kg begin accelerated along the floor at 3.1 m/s^2.

A certain vehicle passes through the two-mile markers with an average speed of 77 miles per hour, and the distance between the markers is 5280 ft ± (50 ft). If the officer uses a stopwatch to measure the transit time, and his reaction time uncertainty to any single event is 0.05 sec, what is the uncertainty in the aircraft-based speed measurement? calculation work shown either by hand or mathcad
- a Cepheid variable star is a star whose brightness alternately increases and decreases. For a certain star, the interval between times of maximum brightness is 6.5 days. The average brightness of this star is 3.0 and its brightness changes by ±0.35.
