O 10-3 O 10-6 O 103 O 106The radius of the earth is 6,380 kilometers. What is the radius of the earth in centimeters? 638x102cm 638x1ocm 638x1050m e38x1o4cm a38x1086m In the calculation of the area of a rectangle with dimensions of 4.282 m by 0.050 m, which of the following answers has the correct number of significant figures? In the study of physics, what distinguishes a scalar from a vector? Scalars have both a magnitude and a direction, but vectors have only a magnitude. Ascalar must always be positive, but vectors can be positive, negative, or zero. A scalar is a dimensionless number, while vectors are numbers that have dimensions. Ascalar is specified with a single number. but a vector is specified using both a magnitude and a direction. Nothingthe terms \"vector" and \"scalar\" are different names for the same thing. Which of the following is a vector? Displacement MESS Speed Distance Temperature Starting from your campsite you walk 3.0 km east, 6.0 km north, 1.0 km east, and then 4.0 km west. How far are you from your campsite? The SI base unit for mass is the kilogram pound gram newton slug
