You should have 10 entries. There should be a minimum of 4 behavioral entries and 4 emotional entries, and the remaining 2 entries can be either type. As you learn more concepts and theories, begin to fill in the third column, justifying your explanation for the behavior or emotion with a psychological theory. You must use a theory to justify your explanation for 8 of the 10 entries, 4 behavioral entries and 4 emotional entries. Date Activity or Emotion Motivation...

1. The surface of a lake will always reflect light. It is less common for a lake to reflect a clear image of buildings and lights on the other side of the lake; this happens most often on still mornings or evenings. a) What is the name for the type of reflection that the lake usually exhibits? b) What is the name for the type of reflection that the lake exhibitswhen it forms clear images? c) What is the cause...

An entrepreneur has proposed sending a probe to Alpha Centai 4 light years away. His idea is to use a "solar sail", which is a large area reflective sheet, and propelling the spacecraft to 10% of the speed of light using a high powered laser. If the laser sends 1200 nm light at the sail and the power reaching the reflective sheet is 1500 W: (a) What is the force due to light pressure on the reflective sheet, assuming the...

Cameras have various mechanisms to control how the light falls onto the light-sensitive surface. Lenses focus the light entering the camera, the size of the aperture can be widened or narrowed to let more or less light into the camera, and a shutter mechanism determines the amount of time the photosensitive surface is exposed to the light. - Write a short report in 5 pages (Word File) about how a camera is used as an optical instrument used to record...
