The student's average speed for the dash was 8.2 m/s. It's not possible to completely describe the student's velocity, because there's no information to tell us what direction she ran.
Answer: 1.044 E -17 A
Explanation:
L =1.50m
A = 0.380mm = 3.8E- 7
Resistivity p =1.70 E-8
R =pl/A
R = 1.70 E-8 × 1.5/ 3.8 E-7
R = 6.71 E-16 ohms
V = IR
0.700 = I × 6.71 E-16
I =1.044E-17 A
