Two charged parallel plates are 0.25 meters away from each other. the field between the plates is 600 . what is the electric potential difference?

There are weak or strong attractive forces between atoms of liquids with a high viscosity

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

The mass of the sun is 1.99×1030kg and its distance to the earth is 1.50×1011m. what is the gravitational force of the sun on the earth?
