Why are temperature swings smaller over coastal lands than inland?
Answer to Problem 1RCQ
Temperature swings smaller over coastal lands than inland because specific heat capacity of water is greater than the specific heat capacity of rocks and soil.
Explanation of Solution
Land is mostly rock and soil. The specific heat capacity of water is greater than the specific heat capacity of rocks and soil. Consequently, ocean near the coastal lands requires more time to get heated and cooled than the inland.
Rocks and soil present in the inland are poor conductors of heat. Therefore, the solar radiation heats the surface above them. Whereas, in the coastal areas, solar radiation causes evaporation of ocean water and hence, gives the effect of cooling.

Express your answer in meters to three significant figures. Learning Goal: To practice Problem-Solving Strategy 4.1 for projectile motion problems. A rock thrown with speed 12.0 m/s and launch angle 30.0 ∘ (above the horizontal) travels a horizontal distance of d = 19.0 m before hitting the ground. From what height was the rock thrown? Use the value g = 9.800 m/s2 for the free-fall acceleration. PROBLEM-SOLVING STRATEGY 4.1 Projectile motion problems MODEL: Is it reasonable to ignore air resistance? If so, use the projectile motion model. VISUALIZE: Establish a coordinate system with the x-axis horizontal and the y-axis vertical. Define symbols and identify what the problem is trying to find. For a launch at angle θ, the initial velocity components are vix=v0cosθ and viy=v0sinθ. SOLVE: The acceleration is known: ax=0 and ay=−g.
