Explanation Given info: The total depth of ice and water is 3.25 m and depth of the layer of ice is 0.38 m . The formula to calculate the velocity of light in ice is, v ice = c n ice Here, v is the velocity of light in medium. c is the velocity of light in vacuum. n is the refractive index of ice. The formula to calculate the time taken by the ray to travel along the ice layer of thickness 0.38 m is, t ice = d ice v ice Here, d ice is the thickness of layer of ice. v ice is the velocity of light in ice. Substitute c n for v ice in the above formula. t ice = d ice v ice = d ice c × n ice Substitute 0.38 m for d ice , 3 × 10 8 m / s for c , 1.31 for n ice in the above formula. v ice = t ice c × n ice = 0.38 m × 1.31 ( 3 × 10 8 m / s ) = 1.65 ns The depth of water is, d water + ice = 3.25 m d i c e = 0.38 m d water = d water+ice + d ice = 3.25 m − 0.38 m d water = 2.87 m The formula to calculate the velocity of light in water is, v water = c n water Here, v is the velocity of light in medium

In the Donkey Kong Country video games you often get around by shooting yourself out of barrel cannons. Donkey Kong wants to launch out of one barrel and land in a different one that is a distance in x of 9.28 m away. To do so he launches himself at a velocity of 22.6 m/s at an angle of 30.0°. At what height does the 2nd barrel need to be for Donkey Kong to land in it? (measure from the height of barrel 1, aka y0=0)

For which value of θ is the range of a projectile fired from ground level a maximum? 90° above the horizontal 45° above the horizontal 55° above the horizontal 30° above the horizontal 60° above the horizontal

A map from The Legend of Zelda: The Breath of the Wild shows that Zora's Domain is 7.55 km in a direction 25.0° north of east from Gerudo Town. The same map shows that the Korok Forest is 3.13 km in a direction 55.0° west of north from Zora's Domain. The figure below shows the location of these three places. Modeling Hyrule as flat, use this information to find the displacement from Gerudo Town to Korok Forest. What is the magnitude of the displacement? Find the angle of the displacement. Measure the angle in degrees north of east of Gerudo Town.
