a. Diagrammatic question: 1. From the graph of velocity and time, answer the following questions: In which portion of the curve; (i) А is the velocity uniform? (ii) is velocity increasing? (iii) is velocity decreasing? O (iv) is acceleration zero? B velocity IC D time b. At which point does the body start to move and stop ? Modern Graded Science Class 9​

explanation:

earth's surface is mainly heated by the absorption of infrared radiation from the sun.

evaporation occurs because molecules in liquid water are warmed ( usually by the sun) and vibrate quicker, becoming less dense and rise.

condensation occurs because molecules in water vapor are cooled and therefore vibrate more slowly thus becoming more dense and eventually fall to earth.

lines of equal barometric pressure on a weather map are called: isobars : lines of equal temp on a weather map are called: isotherms.​

ice to water 1 water to vapour 2 latent heat

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
