The total lifetime of the sun is about 10 billion years, from when it was born to when it dies, and the half-life of 238u is 4.5 billion years. suppose a particular meteoroid contained 24 micrograms of uranium-238 (238u) when the sun was born. if the meteoroid is still in orbit when the sun dies, it will contain

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.
