Frequency and wavelength are inversely related. That is, when frequency increases, the value of the wavelength decreases and vice versa. The constant of proportionality of the relation is the speed of light that has a value of 3.0x10^8 m/s. We calculate as follows:
wavelength = speed of light /frequency
488x10^-9 = 3.8x10^8 / frequency
frequency = 6.15x10^14 /s = 6.15x10^14 Hz ------> OPTION 3
<span>The answer is C. temperature, light level, species of bacteria. All three variables are considerations regarding the reproduction rate of the bacteria. The other three answer choices can be eliminated easily because they each contain at least one irrelevant variable. In particular, all three contain a variable that makes reference to Jack's personal characteristics. These do not have any impact on the experiment and readily stand out to disqualify the entire answer choice.</span>
C) volume and temperature.
the speed of light is the right answer
Answer:
The final kinetic energy is four times of initial kinetic energy when speed of the car doubles.
= 4 
Explanation:
Mass of the car = 770 kg
initial speed 
= 23.1 
Final speed 
= 46.2
Initial kinetic energy = 
⇒ = 0.5 × 770 × 
⇒ = 205440 J
Final kinetic energy = 
⇒ = 0.5× 770 × 
⇒ = 821760 J
Thus = 4
Therefore the final kinetic energy is four times of initial kinetic energy when speed of the car doubles.
