Answer:
1 × 10⁶ N/C
Explanation:
The magnitude of the electric field between the membrane = surface density / permittivity of free space = 10 ⁻⁵C/ m² / (8.85 × 10⁻¹²N⁻¹m⁻²C²) = 1.13 × 10⁶ N/C approx 1 × 10⁶ N/C
Explanation:
Balanced forces will cause no change in the speed of an object.
The frequency of sodium light in vacuum is 5 ×
Hz.
Answer:
Option e
Explanation:
It is known that frequency of a wave is inversely proportional to the wavelength of the wave. And the proportionality constant is the speed of light in vacuum. As the speed of light in vacuum is known as 3×
m/s and the wavelength of the light in vacuum is given as 6 × 
m, then the frequency of the light is determined as
Frequency = Speed of light in vacuum/Wavelength of light
Frequency = 
Frequency = 0.5×
= 5 × Hz.
So the frequency of sodium light in vacuum is 5 × Hz.
A. Density of water vapor.
Answer:
A)Temperature at which liquid starts to become gas.
Explanation:
Boiling point is the temperature at which a liquid boils and turns to vapour or gas.
From the law's of physics, we can know about the different boiling points for different liquids. As an example: at 100 °C temperature the water starts to change into the vapor. It's the boiling point of the water.
