a) On the surface of the earth we receive about 1.37kW of energy per meter
square coming from the Sun. Calculate the electric field associated with sunlight (in
the surface of the earth), assuming that it is essentially monochromatic with λ = 6000Ǻ.
b) On the surface of the earth we receive approximately 1370 W / m2 of energy.
Show that the radiation pressure is close to 4.6 μPa (1Pa≈10-5 N m-2).
c) A sodium lamp (λ≈5890Ǻ) of 100 W of power emits waves evenly
in all directions. What is the radiation pressure at a distance of 10 m from the
bulb?

The power of sunlight reaching each square meter of the Earth's surface on a clear day in the tropics is close to 1 000 W. On a winter day in Manitoba, the power concentration of sunlight can be 100 W/m2. Many human activities are described by a power per unit area on the order of 102 W/m2 or less. (a) Consider, for example, a family of four paying $66 to the electric company every 30 days for 615 kWh of...

5. Surface energy (2 pts). Let’s use the concept of surface tension as surface energy per unit area to see if we can estimate, at least to the correct order of magnitude, the surface tension of water. a) Water has a molar mass of 18 g/mol and a density of 1000 kg/m3 (or 1 g/cm3). Based on this data, estimate the number of water molecules per unit surface area of water. b) The coordination number of water (i.e., the average...

Jerome read that in temperate climes, there are more than 133 spiders per square meter of open land with a standard deviation of 4. To test this, he fenced off 31 square meters and carefully counted all the spiders. He found an average of 134.22 spiders per square meter. Which of the following correctly describes the test and hypotheses he should use? A. A z-test with H0:μ≤133, Ha:μ>133 B. A t-test with H0:μ≥133, Ha:μ<133 C. A t-test with H0:μ≤133, Ha:μ>133...

Near the surface of the Earth there is an electric field of about 150 V/m which points downward. Two identical balls with mass 0.407kg are dropped from a height of 2.29m , but one of the balls is positively charged with q1 = 338?C , and the second is negatively charged with q2=-338?C . Use conservation of energy to determine the difference in the speeds of the two balls when they hit the ground. (Neglect air resistance.)
