Answer:
633 nm
Explanation:
E = Energy difference = 1.96 eV
c = Speed of light = 3×10⁸ m/s
h = Planck's constant = 6.626×10⁻³⁴ J/s
Converting eV to J
1 eV = 1.6×10⁻¹⁹ J
1.96 eV = 1.96×1.6×10⁻¹⁹ Joule = 3.136×10⁻¹⁹ Joule
Photon energy equation
∴ Wavelength of light emitted by this laser is 633 nm
the answer on edginuity is B- Fluids (i just took the test)
Using fossil fuels to generate electricity doesn't take spinning turbines. Using the force of the wind (wind energy) to generate does contain spinning, though not of generators.
Answer:
maximum speed of the bananas is 18.8183 m/s
Explanation:
Given data
amplitude A = 23.195 cm
spring constant K = 15.2676 N/m
mass of the bananas m = 56.9816 kg
to find out
maximum speed of the bananas
solution
we know that radial oscillation frequency formula that is = √(K/A)
radial oscillation frequency = √(15.2676/23.195)
radial oscillation frequency is 0.8113125 rad/s
so maximum speed of the bananas = radial oscillation frequency × amplitude
maximum speed of the bananas = 0.8113125 × 23.195
maximum speed of the bananas is 18.8183 m/s
