Using the kinetic energy 1/2mv^2 formula
5*10^5 is the answer
Answer:
I think the answer must be A.
-- reduce the length of a wire to 1/2 . . . cut the resistance in half
-- reduce the diameter to 1/4 . . . reduce the cross-section area by (1/4²) . . . increase the resistance by 16x .
-- R2 = (R1) · (1/2) · (16) = 8 · R1
<em>-- R2 / R1 = 8</em>
Why is it always balloons?
anyways so the balloon volume goes somewhere else when it shrinks because the balloon is losing air i think
Volcanic Island arcs form when an <u>oceanic tectonic</u> plate is subducted below a <u>tectonic plate </u> taking seawater with it.
Volcanic island arcs occur offshore during volcanoes. They occur due to the subduction of an oceanic plate under another tectonic plate. Volcanic Island arcs occur mostly in ocean basins.
Due to the subduction of oceanic plates under tectonic plates, Island Arcs are found, mostly along the margins of continent.
Hence we can conclude that Volcanic Island arcs Form when an <u>oceanic tectonic</u> plate is subducted below a <u>tectonic plate </u> taking seawater with it.
