A pendulum with a length of precisely 0.98 m can be used to measure the acceleration due to gravity, g. Such a device is called a gravimeter.How long do 80 oscillations take at sea level, where g= 9.81 m/s2? Suppose you take a gravimeter to a spot on Venus where the value of g is 0.89% less than the value of g at sea level on Earth. How long do 80 oscillations take at this place on Venus? Would you be able...
This is a projectile motion question. Assume the acceleration due to gravity is g = 9.81 m/s2. What is the magnitude of the vertical displacement in metres if the initial velocity has a magnitude of 23.6 metres/second at an angle of 41.3 degrees below the horizon and the time of flight is 1.8 seconds. I want the size here, not the size and the direction. I have already given you the direction in the question.
This is a projectile motion question. Assume the acceleration due to gravity is g = 9.81 m/s2. What is the time of flight in seconds if the initial velocity has a magnitude of 21.5 metres/second at an angle of 58.4 degrees above the horizon and the range of the projectile is 52.7 metres. Give me your final answer as a number with decimal places, not scientific notation.
28. In a simple pendulum experiment for determination of acceleration due to gravity (g), time taken for 20 oscillations is measured by using a watch of 1 second least count. The mean value of time taken comes out to be 30 s. The length of pendulum is measured by using a meter scale of least count 1 mm and the value obtained is 55.0 cm. The percentage error in the determination of g is close to (a) 0.7% (b) 6.8%...
A measurement of the acceleration of gravity g is made and the data set is used to calculate a mean and a standard deviation. The mean is 10.00 m/s2, and the standard deviation is 0.67 m/s2. 1. What range of values for g would include about 70% of the data set? What range would include about 95% of the data set? 70% Range: to m/s2. 95% Range: to m/s2. If you have two sets of measurements, and know the mean and standard deviation of...

a=g(ΔmmT)m/s2 For a frictionless pulley, g is the free fall acceleration due to gravity but in practice, pulleys have friction so g is smaller. Assume your pulley has friction such that g=9 m/s2. You hang two masses on either side of your pulley. M1 has a mass of 169 g. M2 has a mass of 277 g. What is the acceleration of the masses as they fall?
For flow in a pipe of uniform diameter D the loss in hydraulic head, h, is given by: L u2 D 2 where L is the length of the pipe, u is the average flow velocity, g is the acceleration due to gravity and f is a constant. During reconfiguration of a plant it is estimated that the length of the pipe could be reduced by 15% and its diameter increased by 6%. Calculate the maximum percentage by which The...
