First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
Answer:
Explanation:
wavelength of light = 4 x 10⁻⁷ m
frequency = velocity in air / 4 x 10⁻⁷
= 3 x 10⁸ / 4 x 10⁻⁷
= .75 x 10¹⁵ Hz
= 75 x 10¹³ Hz.
Wave length = 4 x 10⁻⁷ m
= 400 x 10⁻⁹m
400 nm
colour of light having this wavelength in air is violet .

I’m honestly bored & tiredddd
A). 1,000 watts = 1 kilowatt
5,000 watts = 5 kilowatts
b). (5 kilowatts) x (2 hours) = 10 kilowatt-hours (kWh)
c). (10 kWh) x (15 cents/kWh) = $1.50
