A 0.30-m-thick sheet of ice covers a lake. The air temperature at the ice surface is −15∘C In five minutes, the ice thickens by a small amount. Assume that no heat flows from the ground below into the water and that the added ice is very thin compared to 0.30 m. Find the number of millimeters by which the ice thicken please do not skip steps

A narrow beam of light from a laser travels through air (n = 1.00) and strikes the surface of the water (n = 1.33) in a lake at point A. The angle of incidence is 68 degrees. The depth of the lake is 3.0 m. On the flat lake-bottom is point B, directly below point A. (a) If refraction did not occur, how far away from point B would the laser beam strike the lakebottom? (b) Considering refraction, how far...

A submarine is 282 m horizontally from the shore of a freshwater lake and 110 m beneath the surface of the water. A laser beam is sent from the submarine so that the beam strikes the surface of the water 209 m from the shore. A building stands on the shore, and the laser beam hits a target at the top of the building. The goal is to find the height of the target above sea level. (a) Draw a...

An ice cube floats in a beaker of ice cold water. Since the water is ice cold, the ice cube is not melting and hence its volume is not changing. The density of water and ice are, respectively, ρw = 1,000 kg/m3 and ρi = 917 kg/m3. (Assume one of the ice cube's faces is parallel to the water's surface.) (a) If the ice cube is 17.0 mm on each side, how far below the surface (in mm) is the...

A 0.304-m-thick sheet of ice covers a lake. The air temperature at the ice surface is -19.0 °C. In 6.00 minutes, the ice thickens by a small amount. Assume that no heat flows from the ground below into the water and that the added ice is very thin compared to 0.304 m. Calculate the number of millimeters by which the ice thickens
