Which describes the combination of two primary colors of light to produce a secondary color of light?
a. Yellow light and blue light combine to produce green light.
b. Magenta light and cyan light combine to produce blue light.
c. Red light and green light combine to produce yellow light.
d. Green light and yellow light combine to produce white light.
Answer:
b. Magenta light and cyan light combine to produce blue light.
Explanation:
Primary colour is any of three colours which, when added to or subtracted from others in different amounts, can generate all other colours.
• Red, blue and green are additive primary colours..
• Magenta, yellow and cyan are subtractive primary colours.
<span>Cobalt-60 is undergoing a radioactivity decay.
The formula of the decay is n=N(1/2)</span>∧(T/t).
<span>Where N </span>⇒ original mass of cobalt
<span> n </span>⇒ remaining mass of cobalt after 3 years
T ⇒ decaying period
t ⇒ half-life of cobalt.
So,
0.675 = 1 × 0.5∧(3/t)
log 0.675 = log 0.5∧(3/t)
3/t = log 0.675 ÷log 0.5
3/t= 0.567
t = 3÷0.567
= 5.290626524
the half-life of Cobalt-60 is 5.29 years.
