Let's say you have a plot for pendulum experiment. let's assume g for this experiment was measured (from the slope of the plot) to be 9.78 [ms-2. the vertical intercept, however, is 0.021 [s2]. what might this translate to for a measurement of the length offset systematic in all the length measurements?

What is the measure of a change in an objects velocity?

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
