You see a coin at the bottom of a pool. The light reflects from the coin to the surface forming an angle of Θ1 = 10° with the normal. If water has an index of refraction of 1.33, determine Θ2. [Round to the nearest tenth.]

A) 13.3°
B) 14.9°
C) 22.5°
D) 28.7°

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Magma  is composed of molten rock and is  stored  in the earth's crust. lava is  magma  that reaches the surface of our planet through a volcano vent.

No because scientist are still changing there mines today so they are not correct to this day
