The speed of light is 3times 10^8m/s How far will an electromagnetic wave (light) trave in one year (answer in meters). This distance is known as a lightyear. Conversions: 1 year =365 days 1day=24hours 1 hour = 60 min 1min=60s18) Lighting strikes all around the world at a constant rate yet we see that buildings are not constantly being set on fire. Draw a diagram and explain how tall buildings can handle year-round lighting strikes (3)3: Why do modern vehicles have airbags, and how do they work with crumple zones? Section 6: Conservation of Momentum 1:Explain the law of conservation of momentum. 2: What happens when two cars of equal mass collide head-on while traveling at the same speed? 3: If a heavier car collides with a lighter car,which car experiences more force?
