A deuteron consists of one proton and one neutron. A deuteron moving horizontally enters a uniform, verticle magnetic field of 0.500 T. It then travels in a circular arc radius 55.6 cm. How fast was the deuteron moving just before it entered the field? Let the mass of the deuteron m=3.34*10^-27 kg and the charge on a proton q=1.60*10^-19 C.
7.52*10^6 m/s
3.34*10^7 m/s
9.94*10^7 m/s
1.33*10^7 m/s

answer and explanation;

composition refers to both the types of minerals within a rock and the overall chemical makeup of the rock while texture refers to the size and arrangement of the minerals or grains that make up a rock. both composition and texture can be used to classify rocks, such as igneous rocks. texture describes how the rock became solid or crystallized from liquid, melted rock. composition of a rock describes the minerals that make up a particular rock.
