The acceleration of the dragster is modeled as a D c1 c2v2, where the v2-term accounts for aerodynamic drag and where c1 and c2 are positive constants. If, from wind tunnel tests, c2 is known, determine the value of c1 so that the final speed is vf , assuming it starts from rest and travels a distance d to the finish. A

What is the energy of a photon of ultraviolet radiation with a frequency of 4.4 × 1015 hz? planck’s constant is 6.63 × 10–34

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

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.)
