In general, all views of the cosmic microwave background are identical. Isotropy is demonstrated by this.

<h3>What exactly is isotropy, for instance?</h3>

The Greek words isos (equal) and tropos, from which the term "isotropy" is derived, mean "uniform in all directions" (way). The material properties of anisotropic materials, such as graphite, differ depending on the direction, in contrast to isotropic materials like glass, which show the same properties in all directions.

There is no "centre" to an isotropic universe, which is another characteristic. The North and South Poles are produced by the rotation of the Earth, giving them a distinctive orientation, but the Universe is visible from every angle. When we think about the Big Bang, which is the origin of the Universe, this is a crucial point.

Austin invested $11,000 in an account paying an interest rate of 5.7% compounded quarterly. Assuming no deposits or withdrawals

daser333 [38]

Answer:

15448

Explanation:

Compounded Quarterly:

A=P\left(1+\frac{r}{n}\right)^{nt}

A=P(1+

)

Compound interest formula

P=11000\hspace{35px}r=0.057\hspace{35px}t=6\hspace{35px}n=4

P=11000r=0.057t=6n=4

Given values

A=11000\left(1+\frac{0.057}{4}\right)^{4(6)}

A=11000(1+

0.057

)

4(6)

Plug in values

A=11000(1.01425)^{24}

A=11000(1.01425)

Simplify

A=15448.0290759

You are standing on a sheet of ice that covers the football stadium parking lot in Buffalo; there is

Arlecino [84]

Answer:

a) $v=0.5405\ m.s^{-1}$

b) $v_p'=0.1143\ m.s^{-1}$

Explanation:

Given:

mass of ball, $m_b=4\ kg$

initial speed of the ball, $v_b=10\ m.s^{-1}$

mass of the person, $m_p=70\ kg$

Using the conservation of linear momentum:

When the person catches the ball, assuming that the person catches it with an impact without absorbing the shock.

$m_b.v_b=(m_b+m_p)v$

$4\times 10=(4+70)\times v$

$v=0.5405\ m.s^{-1}$

When the ball hits the person and bounces off with the velocity of $v_b'=8\ m.s^{-1}$ .

Using the conservation of linear momentum:

$m_b.v_b+m_p.v_p=m_b.v_b'+m_p.v_p'$

where:

$v_b'=$ final speed of the ball after collision

$v_p'=$ final speed of the person after collision

$v_p=$ initial velocity of the person = 0

putting the respective values in the above eq.

$4\times 10+0=4\times 8+70\times v_p'$

$v_p'=0.1143\ m.s^{-1}$

Explanation:

The rest of the question is written below:

a. What is the final speed of the falcon and pigeon?

b. What is the average force on the pigeon during the impact?

<h3>a) Final speed</h3>

This part can be solved by the Conservation of linear momentum principle, which establishes the initial momentum $p_{i}$ before the collision must be equal to the final momentum $p_{f}$ after the collision:
