There Are Eight And Two In The Attachmentsq1 Because Earths Rotatio Because Earth's rotation is gradually slowing, the length of each day increases: The day at the end of 1.0 century is 1.0 ms longer than the day at the start of the century. In 91 centuries, what is the total of the daily increases in time (that is, the sum of the gain on the first day, the gain on the second day, etc.)? Gold, which has a density of 19.32 g/cm³, is the most ductile metal and can be pressed into a thin leaf or drawn out into a long fiber. (a) If a sample of gold with a mass of 3.261 g is pressed into a leaf of 4.019 µm thickness, what is the area of the leaf? (b) If, instead, the gold is drawn out into a cylindrical fiber of radius 2.400 µm, what is the length of the fiber? Grains of fine California beach sand are approximately spheres with an average radius of 50 µm and are made of silicon dioxide, which has a density of 2.8 × 10³ kg/m³. What mass of sand grains would have a total surface area equal to that of a cube with an edge length of 1.1 m? One cubic centimeter of a cumulus contains 330 water drops, each with a radius of 10 µm. (a) How many cubic meters of water are in a cylindrical cumulus cloud of height 3.2 km and radius 0.9 km? (b) How many 1-liter pop bottles would that water fill? (c) Water has a density of 1000 kg/m³. What is the mass of the water in the cloud? You are preparing dinners for 400 people at a convention of Mexican food fans. The recipe calls for 3 peppers per serving, with one serving per person. Habanero peppers have a spiciness of 300,000 SHU, while the average pepper has 4,000 SHU. How many habanero peppers should you substitute for the original peppers to achieve the desired spiciness? A man stands still from t=0 to t=4.07 min, then walks briskly at a constant speed of 2.47 m/s from t=4.07 min to t=8.14 min. What are (a) his average velocity from 1.00 min to 5.07 min and (b) his average acceleration over this period? Similarly, what are (c) his average velocity from 2.00 min to 6.07 min and (d) his average acceleration over this period? A moist clay ball falls 19.2 m to the ground and contacts the ground for 22.0 ms before stopping. (a) What is the average acceleration during contact? (b) Is this acceleration directed upward or downward? The NASA Glenn Research Center’s Zero Gravity Research Facility includes a 138 m drop tower. A sphere of 1 m diameter is dropped inside this evacuated tower. (a) How long is the sphere in free fall? (b) What is its speed upon reaching the bottom? (c) When it is caught, it experiences an average deceleration
