Don‘t know the answer to these questions, any help would be appreciated :)When a positive charge enters a motor, it passes through a coil of wire. What type of field does the flow of charge create?A) electric field B) force field C) gravitational field D) magnetic fieldParallel wires X and Y carry electric currents. What will be the result if the direction of the current in wire X is reversed? A) The current in wire Y will reverse. B) The magnetic forces on both wires will reverse. C) The magnetic force on wire X will only reverse D) The magnetic force on wire Y will only reverseAccording to the domain theory, what will happen to the domains in a ferromagnetic material placed in a magnetic field whose strength is increased? A) The alignment of the domains will be reversed.B) Less alignment of the domains will take place C) More alignment of the domains will take placeD) No change will occurUmm I think the first one is A, second is B, and third is C.but I‘m not sure D:
1) The positive charge when it is moving generate a magnetic field. 2) I think is B. Because if one current is reversed, the force now well become in repulsion. Before was attraction. 3) In a ferromagnetic material, the domain will take place aligned to the magnetic field. That will happen while the ferromagnetic material do not enter in saturation. I take the B, because in the question say that the field is incrementing. Se you!!
I additionally field backyard, or maybe with the actual undeniable fact that I had a diverse set up as you (I purely used Miracle improve backyard Soil), I did use Bone and Blood meal in my backyard. In all honesty, there rather isn't a trick I used to function those issues to my boxes. I examine and observed the guidelines for use according to foot (or despite section they used), and did (in many situations an equality equation) math to the dimensions of my boxes, after which basically rounded up for practicality applications. i does not upload yet another bag or perlite. Your soil is probable already very easy, and till you intend on watering it your self, won't get as lots water from rainfall as a backyard out interior the open, subsequently leaving the perlite out will improve water retention. including lime to your soil probable won't advance your soil. Lime is used for elevating your pH tiers of the soil. i don't consider getting an entire-blown soil try, specifically because of the fact it is going to fee money and you rather already understand what's on your soil (it is in contrast to your transforming into in organic soil on your outdoor). If something, it is right to have a pH on the low component, decrease than 7.0, and that i'm keen to guess your soil is already there.
If the charged particle is electron, on the same time as flow contained in direction of the magnet, it resembles the electron that flow in a updated wearing cord. Use your left hand flemming rule(you need to opt to appreciate by way of now). you will understand the way they(electron) strikes. undergo in thoughts, electron strikes oppositely with present day. For the fairly charged ion, the concept keeps to be an same, only opposite the direction of the electrons that being deflected on the same time as bypass contained in direction of the magnetic fields. So, my answer must be B.(i'm no longer fairly beneficial thinking i'm no longer conscious of the interest parabolic, besides the fact that it does advise curve, stable?)
you should use new compost (growbags) or you risk any disease or pests that may have overwintered in the old stuff attacking your plants. most of the nutrients would have been used last year anyway. it is good to throw onto your garden though.
Always start with new dirt, the old dirt will be depleted of nutrients. Fill in low spots in your yard with the old dirt.
