Consider each of the electric- and magnetic-field orientations given next. in each case, what is the direction of propagation of the wave? (a) e in the +x-direction, b in the +y-direction; (b) e in the -y-direction, b in the +x-direction; (c) e in the +z-direction, b in the -x-direction; (d) e in the +y-direction, b in the -z-direction.

the first american roller coaster was the mauch chunk switchback railway, built in the mountains of pennsylvania in the mid-1800s. the track, originally built to send coal to a railway, was reconfigured as a "scenic tour."

false br

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer
