Two planets a and B of same mass and same radius are shown in the figure even and P2 are densities of the material in the planets and P1 is greater than PT if the acceleration due to gravity on the surfaces of the planets are G1 G2 respectively then

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error

Which pair of quantities includes one quantity that increases as the other decreases during simple harmonic motion?
