The correct answer is (b). A pyrheliometer is a device used to measure the direct, normal incidence of solar radiation. It is a type of pyranometer, which is a device that measures solar radiation. Pyrheliometers are used in a variety of applications, including meteorology, astronomy, and agriculture.<\/p>\n
(a) Sun spots are dark areas on the surface of the sun. They are caused by magnetic activity on the sun. Sun spots can be observed with a telescope or with a special camera called a solar filter.<\/p>\n
(c) Air temperature is the temperature of the air. It is measured with a thermometer. Air temperature can vary depending on the time of day, the season, and the location.<\/p>\n
(d) The temperature of plants is the temperature of the plant’s tissues. It is measured with a thermometer. The temperature of plants can vary depending on the type of plant, the time of day, and the environment.<\/p>\n","protected":false},"excerpt":{"rendered":"
