Aseaplane of total mass m lands on a lake with initial speed viî. the only horizontal force on it is a resistive force on its pontoons from the water. the resistive force is proportional to the velocity of the seaplane: r = −bv. newton's second law applied to the plane is −bvî = m(dv/dt)î. from the fundamental theorem of calculus, this differential equation implies that the speed changes according to

What is the type of the reaction below? bacl2 + h2so4 → 2 hci + baso4 double replacement synthesis single replacement decomposition

Aquarterback pedals 3.3meters southward and then run 5.7meters northward. whats the distance ? and whats the displacement?

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.)
