If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that Protons have moved to the rod

Friction destroyed the electrons in the rod

The silk has become negatively charged

Glass attracts more protons​

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

The process of predicting values that extend beyond the range of data points is called absolute value extrapolation interpolation prediction for any given: )
