Acoil 4.00 cm in radius, containing 500 turns, is placed in a uniform magnetic field that varies with time according to b = 10.0120 t> s2t + 13.00 * 10-5 t> s 4 2t 4 . the coil is connected to a 600@ω resistor, and its plane is perpendicular to the magnetic field. you can ignore the resistance of the coil. (a) find the magnitude of the induced emf in the coil as a function of time. (b) what is the current in the resistor at time t = 5.00 s?

The energy released by a chemical reaction can be measured using a calorimeter. when barium hydroxide octahydrate crystals are reacted with dry ammonium chloride inside of a coffee cup calorimeter, the temperature of the 18.00 g of water in the calorimeter decreases from 30.0°c to 8.0°c. the equation for calculating energy absorbed or released by a reaction is: where q is the energy released or absorbed, m is the mass of water in the calorimeter, cp is the specific heat of water, and δt is the observed temperature change. if the specific heat of liquid water is 4.19 j/g·°c, how much energy was absorbed by the reaction?
