Chapter 29, Problem 67P
The Voyager I spacecraft is now beyond the outer reaches of our solar system, but earthbound scientists still receive data from the spacecraft's 20-W radio transmitter. Voyager is expected to continue transmitting until about 2025, when it will be some 25 billion km from Earth. What's the diameter of a dish antenna that will receive 10−20 W of power from Voyager at this time?

On December 27, 2004, astronomers observed the brightest flash of light ever recorded from
outside of our solar system. It came from a highly magnetic neutron star SGR 1806-20 (also know
as a magnetar). During the 0.20 s burst, this star released as much energy as our sun would over
a period of 250,000 years. If our sun outputs approximately Psun = 3.846x 1026 W, what was the
average power output of this magnetar in terms of Psun?
The intensity of electromagnetic energy from the Sun reaching the
Earth is 1,390 W/m?. Earth is about 1.5 x 1011 m from the Sun and
Saturn is about 10 times further, how much power would a 1.00 m2
solar panel receive at the distance of Saturn?
Provide the solution:
A large container which has 258 g of water initially at 23 °C is placed in a microwave oven. The magnetron in the microwave oven can produce 950 W of EM radiation. The microwave is turned on for 2.5 minutes.
Assuming that all the microwave energy is absorbed by the water, how much water is left in the container?
2. The OXO 8716900 electric kettle (1500 W) manufacturer’s claim that it can boil up to 1.75 L of water faster than the microwave, safer than the stovetop, and runs off a mains voltage of 120 V. Compare the efficiency of the two approaches.
3.Name the different ways of heat loss in these systems (Microwave & Kettle) during the heating process.
