11l consider the atmospheric phenomena listed below. (i) sun pillars (ii) haloes (iii) sun dogs (iv) primary rainbows (v) secondary rainbows (vi) crepuscular rays (vii) clouds if the freezing point of water were to drop so that water no longer froze in our atmosphere, which of the phenomena above would be affected? 121 all of the questions below concern haloes and primary rainbows. (a) do these two phenomena both involve refraction in their production? (b) do these two phenomena both involve reflection in their production? (c) do these two phenomena display the same color order? (d) describe how your answers to parts (a) and (b) above naturally explain your answer to part (c).

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
