0.120 m and released. How much
Potential Energy does it have when
it is 0.0600 m from equilibrium?
(Unit = J)

What is the earliest point in the universe that we can observe? why can’t we see back further than this?

How are calculation for velocity and speed different

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
