Answer:
the skater is falling bc of gravity and kinetic energy
Explanation:
Explanation:
For air, n1 = 1.00003; for water, n2 = 1.3330
Given: θ2 = 30 degrees, then
θ1 = arcsin [(n2/n1) sin θ2]
= arcsin [(1.3330/1.0003) sin (40)]
= 58.93 degrees
Note that since, in this example, light is traveling from a medium of higher density (water; n2 = 1.3330) to a medium of lower density (air; n1 = 1.0003), then n2 > n1, and the angle of refraction (θ1) is larger than the angle of incidence (θ2), thus the light bends away from the normal (in this example, the vertical) as it leaves the water and enters the air.

The energy of the red light emitted by a neon atom is 2.827*10^-19J
Light produces photons which might be small packets of power. as the atoms of an object are heated, it results within the manufacturing of photons. The electrons locate pleasure from the warmth and produce extra energy. This power emits inside the shape of a photon, and extra photons are released because the cloth becomes hotter.
The SI unit of wavelength is metre typically denoted as m. at the same time as measuring wavelength the multiples or fractions of a metre is also used. extensively, exponential powers of 10 are used while wavelengths are of a huge property. while there are shorter wavelengths they're expressed as negative exponential.
c=3*10^8 h=6.626*10^-34
wavelength= 703.2*10^-9m
E=2.827*10^-19J
Hence energy of the red light is 2.827*10^-19J.

Answer:
Elastic potential energy is the stored energy of a compressible or stretchable object like a spring or rubber band or molecule. Elastic potential energy is equal to the force times the distance of movement. Elastic potential energy = force x distance of displacement. W = Fs. W = elastic potential energy, in Joules.
