37. a wire carrying a 30.0-a current passes between the poles of a strong magnet that is perpendicular to its field and experiences a 2.16-n force on the 4.00 cm of wire in the field. what is the average field strength

connect the batteries in series and hope

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
