Which of these explanations is describing the law of inertia?" The seat belt must apply more force to stop a child with more mass than a child with
less mass.
If the car stops suddenly, the seat belt and car seat help overcome the inertia of the
child so the child doesn't keep moving and get injured.
When the seat belt pushes on the child, the child pushes back on the seat belt
None of these are examples of the law of inertia

Current 1 of 8.4 a runs for 240 seconds and then stops. current 2 is 10.5 a. how long does current 2 have to un to deliver the same amount of charge as current 1? 88.28 192 s 2016 s 21,000 s

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false

Large electric fields in cell membranes cause ions to move through the cell wall. the field strength in a typical membrane is 1.0 x 10 7 n/c. what is the magnitude of the force on a calcium ion with charge +e? what is its acceleration? is it possible for a particle with the same charge as as calcium to have a different acceleration if placed at this location? what would change the acceleration: mass of the particle? diameter of the particle?
