A rocket ship in space is at rest relative to a rock floating in deep space. The rocket ship accelerates away from the rock at 3 m/s2, while it accelerates it
goes through a displacement of 108 m directly away from the rock. For what
amount of time did it accelerate? Hint: If a variable has the numerical value
zero, then you can substitute the value zero in for that variable before doing
the algebra to make the algebra much simpler.

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.

Scientists follow specific processes in order to determine valid explanations and conclusions from observations. david observed strange lights in the sky above his home outside of roswell, new mexico. the only explanation that makes sense to him is that there are ufos in the area. what should david do next to verify his explanation?
