At t = 0 seconds, a cart is moving with a velocity of 10 cm/s and an acceleration of 4.0 (cm/s)/s. assuming its acceleration stays at this value, what will its velocity be 7.0 seconds later?

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?

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.)
