PLS HELP ASAP I REALLY NEED HELP AND WILL GIVE BRAINLIEST <2 5. A curious physics student asked her teacher "how quickly is Earth moving through
space?" Using the concept of relative velocity, explain why this question does not have an answer.

6. Two students are having a debate about the forces acting on a stationary object.
Lawrence says that, because the object is not moving, there are no forces acting on it.
Paula says that there can still be forces acting on an object, even if it is stationary. Which student is correct, and why?

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
