Use the following questions to check your understanding of some of the many types of visual information used in astronomy. For additional practice, try the Chapter 9 Visual Quiz at Mastering Astronomy.
The image from a MESSENGER flyby shows evidence of impact catering, volcanism, and tectonic activity on Mercury. Answer the following questions based on the image. Remember that craters are bowl-shaped and rough-floored when they form, and wipe out any preexisting features in the area. Lava on Mercury appears to be fairly runny and makes flat smooth plains as it spreads out.
2. The region around 2b has far fewer craters than the region around 2c. The crater floor at 2a is also flat and smooth, without many smaller craters on it. Why are regions 2a and 2b so smooth?
a. Few small craters ever formed in these regions.
b. Erosion erased craters that once existed in these regions.
c. Lava flows covered craters that once existed in these regions.

The wires carry currents of I₁ = 3.50 A, I2 = 5.50 A, and I3 = 8.50 A. Each side of the triangle has a length of 34.0 cm, and the point (A) is located half way between (11) and (12) along one of the sides. Find the magnitude of the magnetic field at point (A). Solve in Teslas (T). I₁arrow_forwardNumber There are four charges, each with a magnitude of 2.38 μC. Two are positive and two are negative. The charges are fixed to the corners of a 0.132-m square, one to a corner, in such a way that the net force on any charge is directed toward the center of the square. Find the magnitude of the net electrostatic force experienced by any charge. ips que Mi Units estic re harrow_forward

- Two very small spheres are initially neutral and separated by a distance of 0.612 m. Suppose that 4.12 × 1013 electrons are removed from one sphere and placed on the other. (a) What is the magnitude of the electrostatic force that acts on each sphere? (b) Is the force attractive or repulsive?arrow_forwardEstimate the diameter of the Moon. During a total solar eclipse, the Moon passes in front of the Sun so that during “totality” their apparent sizes match and the Moon blocks light from the Sun shining on the Earth. a) What do you predict the size of the Moon would be if you were to use a pinhole in an aluminum holder, meter stick, and white paper screen to project light from the full Moon through a pinhole onto a screen that is one meter away from the pinhole? b) Describe in detail how you would use this apparatus and your knowledge of pinhole phenomena to estimate the diameter of the Moon. Assume that the distance between the Earth and the Moon is 250,000 miles.arrow_forwardThe following data was collected for a friction experiment in which an object was observed moving at constant speed over a surface.
