A sedentary lifestyle is when you don't make any exercise. For example, if I spent a whole week just sitting down answering questions, that would be an example of a sedentary lifestyle, because I'm not running or jogging. Having that type of lifestyle can make you fat and get health problems.
Have a nice day! :)
The answer is C 8.87*10^4 m/s (it shouldn't be m/s^2 though as velocity is in m/s)
Since you know the acceleration is 12 m/s^2, the initial velocity is 2.39*10^4 m/s and the time (you have to convert to seconds) is 5400 seconds, then you can use the equation
v = vo + at
When you plug in the values you get
v = 2.39*10^4 + 5400*12 . so v = 8.87*10^4 m/s. C is your answer.
Using Planck's equation,
E = nhc / λ
Also, Power = Energy / time
E = 20 x 10⁻³ x 60 x 60
E = 108 J
108 = (2.29 x 10²⁰ x 6.63 x 10⁻³⁴ x 3 x 10⁸) / λ
λ = 4.22 x 10⁻⁷ m
Yes. The main cause of polarization is by an external electric field. Polarization is characterized by an imbalance of charges where one end is more positive than the other end. When an electric field distorts the charges, there is a shift between the negative and positive poles. This causes the phenomenon called polarization.
