I don't have research to back it up, but exercise is working out. Fitness is taking care of your body, that includes working out and things like eating right.
Answer:
λ = 8.88 x 10⁻⁷ m = 888 nm
Explanation:
The energy band gap is given as:
Energy Gap = E = 1.4 eV
Converting this to Joules (J)
E = (1.4 eV)(1.6 x 10⁻¹⁹ J/1 eV)
E = 2.24 x 10⁻¹⁹ J
The energy required for photovoltaic generation is given as:
E = hc/λ
where,
h = Plank's Constant = 6.63 x 10⁻³⁴ J.s
c = speed of light = 3 x 10⁸ m/s
λ = wavelength of light = ?
Therefore,
2.24 x 10⁻¹⁹ J = (6.63 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/λ
λ = (6.63 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(2.24 x 10⁻¹⁹ J)
<u>λ = 8.88 x 10⁻⁷ m = 888 nm</u>
Answer:B 20 newtons opposite to the direction of the applied force
Explanation:
E) Biotechnology use can lead to an increase in soil erosion and pollution runoff through decreased pesticide use.
Explanation:
Biotechnology use cannot lead to an increase in soil erosion and pollution runoff through decreased pesticide use.
There is no relationship between biotechnology use and increase soil erosion and pollution run off.
Biotechnology involves the application of technology based on living things.
