A pan containing 0.750 kg of water which is initially 13 °Cis heated by electric hob. 35 kj of thermal energy is put into the water and its temperature rises. You can assume that all the energy supplied by the hob goes into raising the temperature of the water. Thee specific heat capacity of water is 4200 J/kg °C To the nearest °C, what is the final temperature of the water?

Which of the following represents a virtual image?

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.)

Give an example of a collision in real life. use the law of conservation of energy to describe the transfer of momentum. be sure and discuss the momentum before and after the collision occurs. you will need at least 3 sentences to thoroughly answer this question.
