In which point the electric intensity of a sphere is maximum

1 answer:

7 0

Here, as the charge is uniformly distributed in the sphere, we will consider s as an area of the sphere which is, s=4πr2 and r is radius of the gaussian surface shown in the figure above. From this, it can be seen that

An unknown fluid has a specific gravity of 0.750. What is the volume of 22.5 kg of this fluid?

Andru [333]

<h2>Option C is the correct answer.</h2>

Explanation:

Specific gravity of fluid = 0.750

Density of fluid = Specific gravity of fluid x Density of water

Density of fluid = 0.750 x 1000

Density of fluid = 750 kg/m³

Mass of fluid = 22.5 kg

We have

Mass = Volume x Density

22.5 = Volume x 750

Volume = 0.03 m³ = 30 L

Option C is the correct answer.
