O bara din cupru poate colisa pe doua mine orizontale ad si ce ale caror capete C si D sunt legate la bornele unui generator cu t. e.m. (E = 10 v) si rezistenta interioara (r=0,5) se neglijeaza rezisteanta sinelor si a barei din cupru. a)Ce intensitate are curentul electric ce se stabileste prin circuitb? b)Se aseaza un magnet in forma de u ca in figura alaturata. laturile sale au o latime de 10 cm. Inductia magnetifca a campului magnetic dintre poli este B =0,05 ce se observa daca bara se lasa libera?

W0lf93. energy flows from the producer level to the consumer level.

Scissors and a seesaw both cut things that’s the only comparison

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
