A student performs an experiment to determine the acceleration due to gravity g. The student throws a steel ball up with initial velocity u and measures the height h travelled by it at different times t. The graph the student should plot on a graph paper to readily obtain the value of g is

In an experiment on simple pendulum to determine the acceleration due to gravity, a student measures the elngth of the thread as 632 cm and diameter of the pendulum bob as 2.256 cm. The student should take the lenght of the pendulum to be

In an experiment of determine acceleration due to gravity by simple pendulum, a student commits 1% positive error in the measurement of length and 3% negative error in the time then % error in g will be

Three students S_1, S_2 and S_3 perform an experiment for determining the acceleration due to gravity (g) using a simple pendulum. They use different lengths of pendulum and record time for different number of oscillations. The observations are as shown in the table. (Least count of length = 0.1 m least count for time = 0.1 s) If E_1, E_2 and E_3 are the percentage errors in 'g' for students 1, 2 and 3 respectively, then the minimum percentage error is obtained by student no._____.

A student performs an experiment an for determination of g(=(4pi^(2)l)/(T^(2))) . The error in length l is Deltal and in time T is DeltaT and n is number of times the reading is taken. The measurment of g is most accurate for

Draw a velocity-time graph for a body moving with an initial velocity u and uniform acceleration a. Use this graph to find the distance travelled by the body in time t.

Student I, II and III perform an experiment for measuring the acceleratioon due to gravity (g) using a simple pendulum . Theu use different lengths of the pedulum and /or record time for different number of oscillations . The observation are shoen in the table . Least count for length =0.1cm Least count for time =0.1s If E_(I) , E_(II) and E_(III) are the percentage errors in g,i.e (Deltag)/(g)xx100 for students I, II, and III respectively ,

A student performed an experiment to measure - pressure and volume of a gas at constant temperature and noted the following: Calculate the value of x and y. Which law was used in the calculations ? Draw graphs to show: volume plotted against pressure.
