Two soccer players start from rest, 38 m apart. They run directly toward each other, both players accelerating. The first player’s acceleration has a magnitude of 0.42 m/s2. The second player’s acceleration has a magnitude of 0.42 m/s2. (a) How much time passes before the players collide? (b) At the instant they collide, how far has the first player run?

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

the higher the current the higher the mag field around it the higher the influence on the compass
