A rectangular strip is measured as 32. 30 m by 210 m. find the area of the strip to the correct number of significant figures. The ride is an ancient greek unit of length, as are the stadium and the plethron. 1 mi : 7. 9 x 10 4 km/s, 1. 2 x 10 3 km/s, 4. 7 x 10 3 km/s, 4. 7 x 10 2 km/s, 1. 7 x 10 1 km/s. 1. 61 km: 1. 1 m/s, 2. 9 m/s, 29 m/s, 1. 0x102 m/s, 1. 4x102 m/s, a soccer field is 115 m long and 85 m wide. Assume the sand is 4. 2 m deep and the diameter of one grain of sand is 1. 20 mm: 1012, 1014, 1016, 1018, 1020, the sun with a mass of 1. 99x1030 kg is composed mostly of hydrogen. The hydrogen atom has a mass of 1. 67 x 10 24 g. estimate the number of hydrogen atoms in the sun: 106, 109, 1030, 1054, 1057, in the equation tvcx.
