Pendulum L = 100.0cm, find the time for 20 oscillations. Repeat the experiment for L = 80.0, 60.0, 50.0,40.0 and 30.0. Question
1) Plot a graph of L against T^2 and determine the slope.
2)plot a graph of log L against log T and measure the slope.
3) make L the subject of the
formula in T = 2π√L/g when g/4π^2 is the shape of graph in (L),find (g).
4)state 3 precautions taken in the experiment.

Observations show that interstellar clouds can have almost any shape and

Atypical jetliner lands at a speed of 146 mi/h and decelerates at the rate of (10.4 mi/h)/s. if the jetliner travels at a constant speed of 146 mi/h for 1.5 s after landing before applying the brakes, what is the total displacement of the jetliner between touchdown on the runway and coming to rest?

Two horses begin at rest. after a few seconds, horse a is traveling with a velocity of 10 m/s west, while horse b is traveling with a velocity of 13 m/s west. which horse had a greater acceleration? a. horse a because its change in velocity was greater than horse b's in the same time. b. horse b because its change in velocity was greater than horse a's in the same time. c. horse b because its change in velocity was the same as horse a's, but it took less time. d. both horses had the same acceleration.
