The correct answer is
<span>
force per unit charge.
In fact, the electric field strength is defined as the electric force per unit charge experienced by a positive test charge located in the electric field. In formula:
</span>

where
E is the electric field strength
F is the electric force experienced by the charge
q is the positive test charge.
Answer:
Visible light
Explanation:
Electromagnetic spectrum is the classification of the electromagnetic waves based on their frequency and wavelength. In order from the shortest to the longest wavelength, we have
Gamma rays
X-rays
Ultraviolet
Visible light
Infrared radiation
Microwaves
Radio waves
All these waves are invisible to human eye, except for the visible light part. Visible light is perceived as a different color by the human eye, depending on the wavelength of the light. In particular, we have:
Violet: 380 - 450 nm
Blue: 450 - 495 nm
Green: 495 - 570 nm
Yellow: 570 nm - 590 nm
Orange: 590 nm - 620 nm
Red: 620 nm - 750 nm
The volume of a substance can directly be calculated by
the ratio of mass and density. That is:
volume = mass / density
Since the mass is 4.5 kg or 4500 grams, therefore:
volume = 4500 g / (8.89 g / cm^3)
<span>volume = 506.19 cm^3</span>
