Answer:
Hence wavelength of the photons produced by the laser is
Explanation:
Given
Efficiency of laser - 30%
As we know
h = plank's constant
c = speed of light
eV0 = band gap
Hence wavelength of the photons produced by the laser is
66W. Explanation: Formula of Power: Worktimetaken. Given: Work = 3960J and time taken = 60.0s. Using the formula: Worktimetaken. = 3960J60.0s. = 66W.
Answer:
Fuel efficiency for highway = 114.08 miles/gallon
Fuel efficiency for city = 98.79 miles/gallon
Explanation:
1 gallon = 3.7854 litres
1 mile = 1.6093 km
Let's first convert the efficiency to km/gallon:
48.5 km/litre = (48.5 * 3.7854) km/gallon
48.5 km/litre = 183.5919 km/gallon (highway)
42.0 km/litre = (42.0 * 3.7854) km/gallon
42.0 km/litre = 158.9868 km/gallon (city)
Next, we convert these to miles/gallon:
183.5919 km/gallon = (183.5919 / 1.6093) miles/gallon
183.5919 km/gallon = 114.08 miles/gallon (highway)
158.9868 km/gallon = (158.9868 /1.6093) miles/gallon
158.9868 km/gallon = 98.79 miles/gallon (city)

It’s not because the steering is better or the brakes are on the right sensitivity. It’s because for some reason, you don’t hear anything else but the engine running. Nothing but the purr of the engine in idle or the roar when you accelerate. No clickety clanks or hard, metal-on-metal noise that makes you feel like your car will get disassembled anytime soon.
