Answer:
The energy of one photon of this light is 4.568 × 10∧ -19 J
Explanation:
Given data:
wavelength = 433.9 nm or 433.9 × 10∧-9 m
The value of speed of light is 3× 10∧8 m/s and plancks constant is 6.626 × 10∧-34 m²Kg/s
Formula:
E= hc/λ
E= energy of photon
h= plancks constant
c= speed of light
λ= wavelength of given light
Solution:
E= hc / λ
E = 6.626 × 10∧-34 m²Kg/s × 3× 10∧8 m/s / 433.9 × 10∧-9 m
E = 19.878 × 10∧-26 m²Kg/s² / 433.9 × 10∧-9 m
E = 0.04568 × 10∧ -17 J (Kg m²/s² =J)
E = 4.568 × 10∧ -19 J
Your answer would be 1. Hope this Helps!
Answer:
The heating element is near the bottom of the kettle because of the way it heats up the water. The water is heated through the flow of electricity meeting resistance in the form of the element.
