Answer:
In a vacuum all light travels the same speed no matter what the wavelength or frequency. Gamma radiation has a smaller wavelength and larger frequency, radio waves a smaller frequency and larger wavelength.
Explanation:
Answer:
C
Explanation:
The law of conservation of energy determines that energy cannot be created or destroyed.
S= 1/2 x 182 x t = 1688.3
t = 1688.3 / 91
time = 18.55 seconds
"1 watt" means 1 joule of energy per second.
75 W means 75 joules/sec .
Energy = (75 Joule/sec) x (12 min) x (60 sec/min)
Energy = (75 x 12 x 60) (Joule-<em>min-sec</em> / <em>sec-min</em>)
<em>Energy = 54,000 Joules</em>
