Answer and Explanation:
The steam of bubbles moves away from the stainless steel screw in the salt solution because in salt solution the molecules of the salts break down in ion form and produce electricity.
The electricity produced by the salt ion is responsible for the movement of bubbles
On the other hand in the solution of sugar no ions are produced and hence no electricity is generated and hence no movement of bubbles.
Answer:
Option d is correct option = Frequency of light is 6.56×10⁻² Hz
Explanation:
Given data:
Frequency of light = ?
wavelength of light = 4.57×10⁹m
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
f = c/λ
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
f = 3×10⁸ m/s / 4.57×10⁹m
f = 0.656×10⁻¹s⁻¹
s⁻¹ = Hz
f = 0.656×10⁻¹ Hz or 6.56×10⁻² Hz
Winds becuase tides are effected by the moon and the moon phases are affected but the earth rotating and gravity has nothing to do with anything
Petrol is a conductor of electricity, because it conducts rather than insulates.
Thats hard as hell just drop out of the class lol
