Speed of light
Explanation:
The value 3.0 x 10⁸m/s is taken as the speed of light.
It is a constant.
- It implies that light travels a distance of 3 x 10⁸ in just one second.
- This value is for the speed of light in a vacuum when there are not particles obstructing its movement.
- The speed of electromagnetic radiations in free space is also taken as the speed of light.
Answer:
in the case of an electric bulb the electrical energy is converted to light and heat . the amount of electrical energy put into a bulb = the amount of light energy (desirable form) plus the heat energy that comes out of the bulb (undesirable form.) I hope it helps bro please follow me
MM of HCl = (1.008 + 35.45) g/mol = 36.458 g/mol
Moles = 35.0 g HCl x (1 mol HCl/36.458 g HCl) = 0.960 mol HCl
