Physics
1 answer:
kramer3 years ago
3 0

Answer:

This is likely possible for a region whose matter density is higher than the normal average.

Explanation:

A galaxy is a collection of lumps in space which are clumped together and interact with each other. There are a lot of speculations on how galaxies were birthed. some believe its formed by a collection of massive gas, dust which eventually collapsed under their own gravitational pull. others says its formed by the combination of large lumps of matter which accumulated forming thee galaxies. The possibility of a galaxy forming is dependent on how massive the matter in the region of the universe is.

You are riding in a hot air balloon that, relative to the ground, has a velocity of 6.0 m/s due east. You see a hawk moving dire
charle [14.2K]

Answer:Velocity = 6.325m/s

Directional angle= 18.43°

Explanation:

Using Right angle triangle

Let Velocity of ballon&hawk be VHB represent the height of the triangle.

Let Velocity of balloon angle ground be VBG represent adjacent of the triangle.

Let Velocity of hawk and ground BE VHG represent the hypothesis.

Theta = opp/Adj= VHB/VBG

using pythagorean

VHG= SQRT(VHB^2+VBG^2)

VHG= sqrt(2^2+6^2)

VHG= sqrt(4+36)

VHG= 6.325m/s

Tan theta= 2/6

Tan theta =0.3333

Tan^-1 0.3333=18.43°

Two concentric circular loops of wire lie on a tabletop, one inside the other. The inner wire has a diameter of 20.0 cm and carr
Harrizon [31]

Answer:

Explanation:

Magnetic field due to circular wire at the center = μ₀ I / 2 r

I is current and r is radius . μ₀ = 4π x 10⁻⁷.

field B₁ due to inner loop

B₁ = 4π x 10⁻⁷ x 12 / 2 x .20

= 376.8 x 10⁻⁷

Field due to outer loop

B₂ = 4π x 10⁻⁷ x I / 2 x .30

For equilibrium

B₁ = B₂

376.8 x 10⁻⁷ =  4π x 10⁻⁷ x I / 2 x .30

I = 18 A.

The direction should be opposite to that in the inner wire . It should be anti-clockwise.

A rectangular reflecting pool is 56.5 ft wide and 141 ft long. What is the area of the pool in square meters
konstantin123 [22]

By definition, the area of the pool is 740.112 m².

<h3>Definition of area</h3>

The area is the measure of a space delimited by a contour which is called perimeter.

That is, the area gives an idea of ​​how much surface a figure covers and is defined as the measure of the region or surface enclosed by a geometric figure.

<h3>Area of a rectangle</h3>

A rectangle is a flat geometric figure with four sides, of which two sides that are opposite parallel to each other have the same length and the remaining two have another length.

The area of ​​a rectangle is calculated by multiplying the lengths of two contiguous sides of the figure which are different from each other, that is, the length is multiplied by the width:

Area= length× width

<h3>This case</h3>

A rectangular reflecting pool is 56.5 ft wide and 141 ft long. So, the area of the rectangular pool is calculated as:

Area= length× width

Area= 141 ft× 56.5 ft

Solving:

<u><em>Area= 7966.5 ft²= 740.112 m²</em></u> (being 1 ft²= 0.092903 m²)

So, the area of the pool is 740.112 m².
