Hydroelectricity and tidal energy are similar because
vovikov84 [41]

C.  both sources of energy rely on water.

Explanation:

Hydroelectricity and tidal energy are similar energy sources because they both rely on water.

They harness the power of moving water to produce their energy.

  • Tidal energy is the energy derived from moving water as crashing waves in an ocean.
  • Hydroelectricity is produce when water from a dam channel is used to drive heavy turbines.
  • They are both renewable energy sources.

What is the molarity of a solution that contains 9.63 grams of hcl in 1.5 liters of solution
Aleonysh [2.5K]
Molar mass HCl = 36.5 g/mol

number of moles:

mass of solute / molar mass:

9.63 / 36.5 => 0.263 moles

Volume = 1.5 L

M = n / V

M = 0.263 / 1.5

M = 0.1753 mol/L

The equation for photon energy, E, is E=hcλ where h = 6.626×10−34 J⋅s (Planck's constant) and c = 2.99×108 m/s (the speed of lig
masya89 [10]

Answer:

9.133×10^-6 m

Explanation:

A photon is the smallest discrete amount or quantum of electromagnetic radiation. It is the basic unit of all light. Photons are always in motion and, in a vacuum, travel at a constant speed to all observers of 3 x 10^8 m/s.

From the question, the following details were supplied;

Energy of the photon (E) = 4.61×10^−19 J

Speed of light (c) = 2.99×10^8 m/s

Plank's constant (h) = 6.626×10^−34 J⋅s

Wavelength of the photon (λ)= ??? The unknown

From

E=hc/λ

λ= hc/E

Substituting values

λ= 6.626×10^−34 × 2.99×10^8/ 4.61×10^−19

λ= 91.33×10^-7 m

λ= 9.133×10^-6 m
