A photovoltaic array of (solar cells) is 10.0% efficient in gathering solar energy and converting it to electricity. If the average intensity of sunlight on one day is 70.00 W/m2, what area should your array have to gather energy at the rate of 100 W? (b) What is the maximum cost of the array if it must pay for itself in two years of operation averaging 10.0 hours per day? Assume that it earns money at the rate of 9.00 cents per kilowatt-hour.
(a) Seismographs measure the arrival times of earthquakes with a precision of 0.100 s. To get the distance to the epicenter of the quake, geologists compare the arrival times of S- and P-waves, which travel at different speeds. If S- and P-waves travel at 4.00 and 7.20 km/s, respectively, in the region considered, how precisely can the distance to the source of the earthquake be determined? (b) Seismic waves from underground detonations of nuclear bombs can be used to locate the test site and detect violations of test bans. Discuss whether your answer to (a) implies a serious limit to such detection. (Note also that the uncertainty is greater if there is an uncertainty in the propagation speeds of the S- and P-waves.)
A possible means of space flight is to place a perfectly reflecting aluminized sheet into orbit around the Earth and then use the light from the Sun to push this solar sail. Suppose a sail of area A = 6.00 105 m2 and mass m =6.00 103 kg is placed in orbit facing the Sun. Ignore all gravitational effects and assume a solar intensity of 1 370 W/m2. (a) What force is exerted on the sail? (b) What is the sails acceleration? (c) Assuming the acceleration calculated in part (b) remains constant, find the time interval required for the sail to reach the moon, 3.84 108 m away, starting from rest at the Earth.
A device called an insolation meter is used to measure the intensity of sunlight. It has an area of 100 cm2 and registers 6.50 W. What is the intensity in W/m2?
The Earth has a radius of 6.38 x 106 m and is 1.50 x 1011 m from the Sun. The intensity of sunlight at the Earth is 1370 W/m2. a) At what rate does the Sun radiate energy? (This is the total power radiated by the Sun.) b) A solar sail is a large perfect reflector that gets pushed by the Sun's radiation. If there is a 2.5 km x 25. km solar sail that is perpendicular to the sun's radiation at the Earth's distance from the Sun, then what is the total radiation force of sunlight on the sail? c) What is the intensity of sunlight at Jupiter at a distance of 7.78 x 1011 m from the Sun?
The average intensity of sunlight on Earth’s surface is about 1000 ? ?2 ⁄ a. Calculate the solar panel area if the amount of energy that falls on it in 10 hours is 3 × 1012J.b. What intensity would such sunlight have if concentrated by a magnifying glass onto an area 100 times smaller than its own?
The intensity of the Sun's radiation that reaches a particular point on Earth's atmosphere is 1.06 kW/m2. Convert this to W/cm2. Give your answer with two digits of precision.
= Sunlight reaches earth with an intensity of I = 1 kW.m-2. Knowing that the Earth-Sun distance is R₁ R₂ = 228 106 km, work out the intensity of sunlight on Mars in W/m^2. Number Units 148 106 km and that the Mars-Sun distance is
The evaporation of perspiration is the primary mechanism for cooling the human body. Estimate the amount of water you will lose when you bake in the sun on the beach for an hour. Use a value of 1000 W/m2 for the intensity of sunlight and note that the energy required to evaporate a liquid at a particular temperature is approximately equal to the sum of the energy required to raise its temperature to the boiling point and the latent heat of vaporization (determined at the boiling point).
At a certain geographic location, light intensity from the Sun is 900 J/(m² .s). This means that sunlight delivers 900 joules of energy to each square meter of ground in each second. Suppose solar panels are installed on the roof of a house to generate electricity from sunlight. The total area of the solar panels is 25 m². Calculate the maximum electric energy that can be generated per second: Unfortunately, solar panels are not 100% efficient at converting electromagnetic energy to electricity. Suppose the solar panels have an efficiency of 15%. This means that only 15% of the electromagnetic energy incident on the solar panels is converted to electricity, while the rest is reflected or converted to thermal energy. Given this efficiency, calculate the electric energy that can be generated per second:
A cell phone operates at a frequency of 700MHz. What is the wave length of the waves produced as this cell phone send a signal through the air at 20 degrees C to a local cell phone tower? I got .42 m/wave but not sure I set up the equation correctly. Thanks.
The intensity of electromagnetic waves from the sun is 1.4 kW/m2 just above the earth's atmosphere. Eighty percent of this reaches the surface at noon on a clear summer day.
