Assume each tick mark represents 1 cm. Calculate the total displacement from 0 if an object moves 3 cm to the left, then 7 cm to
the right, and then 6 cm to the left. The object moves cm to the left. What is the total distance the object travels? cm
2 answers:
Assuming the positive x-axis is to the right, the displacement (a vector) can be calculated by:
0-3+7-6 = -2 cm, so the object moves 2 cm to the left.
The total distance (a scalar quantity) can be calculated by:
0+3+7+6 = 16 cm, so the object travels a total of 16 cm.
The object moves 2cm to the left.
What is the total distance the object travels? 16cm

Answer:
0.037 A
Explanation:
Magnetic field = B = 1.00 e-4 T
Length = L = 0.380 m
Number of turns = 810
B = μ₀ N I / L
⇒ Current = I = B L / μ₀ N = ( 1 e-4) ( 0.380) / (4π × 10⁻⁷)(810)
= 0.037 A = 37.3 mA
Answer: 50 seconds
Explanation:
1km=1000m
Distance/speed=time
1000/20=50
50 seconds
