Time A Gizmo Warm-up
The reasons for seasons have a lot to do with the angle at
which the Sun's rays hit Earth. To see why, select the
PLATE tab on the Seasons: Why do we have them?
Gizmo. The image shows a solar panel (Plate M) facing
the Sun. Check that the Axis angle is set to 0.
Plate M
1. Click Fire to release 100 "rays" of sunlight. Look next
to "Number of hits" below the plate.
How many of these rays hit Plate M?
2. Click Reset. Change the Axis angle to 40, and click
Fire Reset
Fire. How many rays hit Plate M now?
Als angle
degrees
3. Which do you think will warm up the plate more quickly? (Circle one.)
A. Direct sunlight (sunlight that hits the plate at a 90° angle)
I
B. Indirect sunlight (sunlight that hits the plate at an angle of less than 90°)
Pun or pronohibited

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
