The friends now consider a charged particle with charge q that moves in a region containing a uniform electric field, E, similar to what they've observed in the simulation. They let the length of the plates creating the uniform electric field be L, and the distance between the plates be d. Alston challenges Thana to calculate the maximum speed, v, the charged particle could be moving if it enters the space halfway between and parallel to the two plates and just barely manages to strike one of the plates. Which response is correct?

Answer body lying face up ;

In atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. the two types of charge are equal and opposite. in an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus.

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.
