An asteroid in the asteroid belt
Answer:
.487 s⁻¹
Explanation:
Let damping constant be τ . The equation of decreasing amplitude can be written as
A = A₀ 
A / A₀ = 
At t = 9.43 s , A / A₀ = .01
.01 = 
ln.01 = - 9.43 τ
-4.6 = -9.43τ
τ = .487 s⁻¹
is the magnitude of the magnetic field made by the current
<u>Explanation:</u>
Given data:

Magnetic field of earth, 
We need to find the magnetic field of wire, 
The compass needle moves toward a direction of magnetic field. The current in wire makes a magnetic field in available space where the compass is on the ground. The vector sum of the Earth's magnetic field and the wire's magnetic field represents the net magnetic field, as shown in the attached drawing, expressing the angle:

By substituting the given values, we get
