A student measures the mass 8cm block of brown sugar to be 12.9g. what is the density of the brown sugar.

What is the final velocity of the initial velocity of 25 and -50?

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.)

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
