Answer: drying towels at the beach.
Explanation:
Radiation simply has to do with the energy that is gotten from a particular source and then goes through some materials. It simply means the way energy is being transmitted as waves or heat through a certain medium.
From the options given, the scenario whereby a radiation takes place is when drying towels on the beach.
Speed v = initial speed u + acceleration a x time t
v=u+at = 2 + 4*3 = 14 m/s
<em>Answer: </em>
1. The <em>"contour interval'</em> identifies the standard difference in elevation on a topography graph. It shows the difference in elevation of highest and lowest points on a topography map. In topographic map every fifth contour line is drawn, wider than the contour lines, called as contour index.
2. Geologist usually study all the materials that make up the earth. He can focus on different rock samples from earth's surface. the geologist works to understand history of the planet where we live on, to predict the future by explaining current occurrences.
3. The difference between the top of the plateau and the lowest point in the area of 250 m measurement is called <em>elevation. </em><em>Elevation is the highest point in the area.</em>
<em>4. </em>Damage from earthquakes is determined by <em>"Ritcher scale"</em>. Seismic waves are the vibrations occurs from earthquakes that can travel through the earth. These vibrations can be detected by the Ritcher scale.
