Answer:

Option 2 is correct.

Step-by-step explanation:

We have been given diameter of the tank 9 ft and height of the cylindrical water tank 12 ft

Radius is half of diameter that is 9/2=4.5

Since, water surface is 2 ft from the top

New height will become 12-2=10 ft

We have to find how much water tank contains means the capacity of tank to contain water

We will find volume of the cylindrical water tank by using formula:

volume=\pi\cdot r^2\cdot h

On substituting the values r=4.5,h=10 and\pi=3.14we get

volume=3.14\cdot (4.5)^2\cdot 10

\Rightarrow volume=3.14\20.25\cdot 10

\Rightarrow volume=635.85=636 ft^3

Therefore,Option 2 is correct.

Explain why the speed of light is lower than<br> 3.0 x 108 m/s as it goes through different media.
jekas [21]

Answer:

Sample Response: In a vacuum, there are no atoms or particles that interfere with the path of light. However, in other media, the speed of light is lower than 3.0 × 108 m/s because the wave is continuously absorbed and re-emitted by each atom in its path. The differences in speed are due to the composition of the medium and the density of the particles in the medium.

What is the name for the layer of cells at the back of the eye that contains photoreceptors?
Alona [7]
B.) The retina is the layer containing t<span>he light sensing nerve cells (rods and cones)

The lens helps the eye focus light on the retina, the cornea is the outer transparent structure that covers the iris and helps the eye focus, and the pupil is the opening through which light enters the eye.</span>

Two flat conductors are placed with their inner faces separated by 8 mm. If the surface charge density on one of the inner faces
miskamm [114]

Answer:

= 0.0298V

Explanation:

Electric field between two conductor = σ / ε₀

σ = 33pC/m²

= 33 × 10⁻¹²C/m²

ε₀ = 8.85 × 10 ⁻¹²C²/Nm²

E = 33 × 10⁻¹² /  8.85 × 10 ⁻¹²

  = 3.7288N/C

potential difference between two conductors = Ed

where d = 8mm = 8 × 10 ⁻³m

V = 3.7288 ×  8 × 10 ⁻³

   = 29.83 × 10 ⁻³

    = 0.0298V

A uniform magnetic field of magnitude 0.72 T is directed perpendicular to the plane of a rectangular loop having dimensions 8.2
Liono4ka [1.6K]

Answer:

Explanation:

Magnetic flux is expressed as the product of magnetic field and cross sectional area.

Φ = BAsintheta

Given

B = 0.72T

A = 8.2cm×14cm

A = 0.082m × 0.14m

Area = 0.01148m²

Theta = 90°

Substitute into the formula

Φ = BAsintheta

Φ = 0.72(0.01148)sin90°

Φ = 0.72(0.01148)(1)

Φ = 0.0082656

Hence the magnetic flux through the loop is 8.2656 × 10^-3 Weber
