An electric heater is used to boil small amounts of water and consists of a 11-Ω coil that is immersed directly in the water. It operates from a 120-V socket. How much time is required for the heater to raise the temperature of 0.40 kg of water from 22∘C to the normal boiling point? Take the specific heat capacity of water to be 4186 J/(kg⋅C∘). Number Units

Ornithologists have determined that some species of birds tend to avoid flights over large bodies of water during daylight hours. It is believed that more energy is required to fly over water than land because air generally rises over land and falls over water during the day. (i) A bird with these tendencies is released from an island that is 3 km from the nearest point B on a straight shoreline, flies to a point C on the shoreline, and then flies along the shoreline to its nesting area D. Points B and D are 10 km apart. Assume that the bird instinctively chooses a path that will minimize its energy expenditure. (Round your answers to two decimal places.) (a) In general, if it takes 1.2 times as much energy to fly over water as land, to what point C should the bird fly in order to minimize the total energy expended in returning to its nesting area? km from B (b) Let W and L denote the energy (in joules) per kilometer flown over water and land, respectively. Assuming the bird's energy expenditure is minimized, determine a function for the ratio WL in terms of x, the distance from B to C. W/L = (c) What should the value of W/L be in order for the bird to fly directly to its nesting area D? (d) If the ornithologists observe that birds of a certain species reach the shore at a point 2 km from B, how many times more energy does it take a bird to fly over water than land?

When 8.11 g of a hydrocarbon is burned in a bomb calorimeter, the temperature increases by 3.75∘C. If the heat capacity of the calorimeter is 58.9 J ∘C and it is submerged in 742 mL of water, how much heat (in kJ ) was produced by the hydrocarbon combustion? Use 4.184 J g∘C for the specific heat capacity of water. Your answer should have three significant figures. Provide your answer below: kJ

An electric coffee maker has a heating element that operates at 120 V and with a current of 2.00 A. Assuming the water absorbs all the energy delivered to the heating element, calculate the time interval (in s) during which the temperature of 0.419 kg of water rises from room temperature (23.0∘C) to the boiling point. (The specific heat of water is 4, 186 J/(kg⋅∘C).)
