Brass is an alloy made from copper and zinc. A 590 g brass candlestick has an initial temperature of 98.0°C. If 21,100 J of energy is removed from the candlestick to . °.
lower its temperature to 6.8°C, what is the specific heat of brass?

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
