Answers

Answer 1

Answer:

Correct answer choice is :

C) Brightness

Explanation:

A sheet of white paper seen in the bright sunlight reveals a very different quantity of light than the same sheet of paper seen later that night in a softly illuminated room. Yet we regard the paper as having the same paleness in each case. This is an instance of brightness constancy, our capability to see objects as proceeding to have the same brightness even though light may change their direct visual features.

Answer 2

Answers

1 watt = 1 joule/sec
1800 watts = 1800 joules/sec

   (1800 J/sec) x (20 min) x (60 sec/min)

   = (1800 x 20 x 60) joules = 2,160,000 joules .
