Hela proton having an initial velvocity of 20.0i Mm/s enters a the swiform magnetic field of magnitude 0.300 T with a direc-
si in perpendicular to the proton's velocity. It leaves the
This field-filled region with velocity -20.0j Mm/s. Determine
ed (a) the direction of the magnetic field, (b) the radius of
curvature of the proton's path while in the field, (c) the
distance the proton traveled in the field, and (d) the time
interval during which the proton is in the field.

coil wire, increase current, put iron inside the coil

the correct choice is a .

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

i do.

explanation:

i want to explore the wonders of the universe and find out if there really is life out there. i think the universe is beautiful.
