Question

1. Choose one of the following resource of energy, that has not relation to the heat of the sun: (a) hydro-electric power (b) solar energy (c) wind energy (d) Ocean thermal energy 2. The visible portion of the spectrum forms (a) a quarter (b) one of third - of the solar energy that received on earth surface. (c) two of thirds (d) none of these 3. What divides the earth into the east and west hemisphere: (a) Equator (b) Atlantic ocean (c) north and south poles (d) prime meridian 4.0 at equator is equal: (a) 23.45° (b) 0° (c) 66.55° (d) none of these 5. If the zenith angle is 45° that means the (m) equal: (a) 0.707 (b) 1 (c) 1.414 (d) 2

Answer 1

as hycho electric powder - water in dems depends on the codlés Х cycle which depends on the sun b) solar energy directly depends on sun c.) wind energy- Wind direction and speed depends on the temperature which dependson Х sun docean thermal power. It only depends on the reaction taking place inside the deep earth, (2) Visible postion of the spectrum form (A3) Ə one of third. 3 prime Meridian dende east and west hemisphere. the at the equate = 0 ° Zenith angle 45 the ma smus m= 1.414
