Four different observers are standing in a straight line on a street and hear a siren from a police car. each person recorded their observations in the chart shown. if the people are all lined up on the street at different blocks, and the police siren starts at block 3, which statement describes what block each person is standing at?
a. wycleff is on block 1, lilly is on block 4, quincy is on block 12, and emilia is on block 17.
b. lilly is on block 1, wycleff is on block 4, quincy is on block 12, and emilia is on block 17.
c. lilly is on block 1, wycleff is on block 4, emilia is on block 12, and quincy is on block 17.
d. wycleff is on block 1, lilly is on block 4, emilia is on block 12, and quincy is on block 17.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)

Aspecified volume of space contains an electric field for which the magnitude is given by e=e0cos(ωt). suppose that e0 = 20 v/m and ω = 1.0 × 107 s−1. part a what is the maximum displacement current through a 0.80 m2 cross-sectional area of this volume? express your answer with the appropriate units. idisp,max i d i s p , m a x = nothing nothing request answer part b how would this area have to be oriented relative to the electric field to get this maximum displacement current?
