Some of these particles are charged; therefore. when they enter Earth's magnetic eld. the}.r experience a magletic force. A stream of charged particles travelling with a speed of 3.00 x 1'1?!5 m-'s encomtets Earth's magnetic eld, as shown below. at an alum-11c where the. eld has a magnmde of 1.10 w. 10'." T. Path of total wind at - a pamculat instant in time """""" Assume that the velocity of the solar wind particles is perpendicular to the magnetic field. The radius ofthe circular path that the protons in a solar wind follow expressed in scientific notation, is a.bc x 10':1 m. The values of a, b, c, and d are | l . For example, ifyou find the answer to be 1.23 x 104 m, you would enter your answer as 1234. A copper wire is connected to a battery so that it has a current in it. A segment of the wire is perpendicuiar to a horizontal 3.5 T magnetic field. The length of the wire in the magnetic field is 3.0 cm, and the mass of the wire affected by the magnetic field is 20 g. In order to suspend the segment of wire, the minimum current in the wire must be Select one: D a. 0.044 A O b. 0.23 A O c. 4.4 A Dd. 44A ques'i'm 9 Use the following information to answer the next question. Not yet answered A student used the apparatus shown below to measure the radius of curvature of the path of electrons as they pass M _ d f through a magnetic field that is perpendicular to their path. This experimental design has the voltage as the t _ . . . . am DU 0 manipulated variable, the speed calculated from the voltage, and the radius as the responding variable. 1.00 '3."
