Electric force depends on the charge and the strength of the electric field. The equation that relates the three:
F = Eq where q is the charge and E is the electric field strength.
Answer:
367.57 nm
Explanation:
Given that the speed of the light in certain material is 0.6310 times the speed of light in vacuum.
Speed of light in vacuum = 3×10⁸ m/s
Speed of the light in that material = 0.6310×3×10⁸ m/s = 1.893×10⁸ m/s
The frequency of the light does not change but the wavelength of the light changes with change in the speed when light travels from one medium to another.
Thus, frequency = 5.15×10¹⁴ Hz
Using,
c = frequency × Wavelength
Wavelength = c / frequency = (1.893×10⁸ m/s) / (5.15×10¹⁴ Hz) = 367.57×10⁻⁹ m
Also,
1 nm = 10⁻⁹ m
<u>So, wavelength = 367.57 nm</u>
A cyclist can increase the speed of their bike in various ways such as, changing gears, positioning themselves properly, increase the pedalling rate
<h3>
Ways in which a cyclist can increase the speed of a bicycle</h3>
Bicycle riders could accelerate/ increase their speed in various ways
- By Changing the gears and by doing so increasing the speed
- By Positioning themselves in a streamlined manner, this is so that they become aerodynamic hence they cut across airflow.
- By increase the rate at which they are pedalling the bicycle.
