An ostrich lays the largest bird egg. A typical diameter for an ostrich egg at its widest part (diameter) is 12 cm (0.12 m). Sup

pose an egg of this size rolls
down a slope so that the centripetal acceleration of the shell at its widest part is 0.28 m/s2. What is the tangential speed of that part of the shell?

The centripetal acceleration is the ratio of the tangential speed and the

radius of the shell.

The tangential speed of the part of the shell is approximately <u>0.12961 m/s</u>

Reasons;

The widest diameter of the egg, d = 12 cm = 0.12 m

The given centripetal acceleration, a_c = 0.28 m/s²

Required:

The tangential speed of the bird.

Solution;

\displaystyle Centripetal \ acceleration, \ a_c = \mathbf{\frac{v^2}{r}}

Where;

\displaystyle r = The \ radius \ of \ the \ egg \ shell = \frac{d}{2}

v = The tangential speed

Which gives;

\displaystyle r = \frac{0.12}{2} = 0.06

\displaystyle 0.28 \, m/s^2 = \frac{v^2}{0.06 \, m}

v² = 0.28 m/s² × 0.06 m = 0.0168 m²/s²

v = √(0.0168 m²/s²) ≈ 0.12961 m/s

The tangential speed, v = <u>0.12961 m/s</u>

False. What actually determines the properties of elements are the electrons, or aka valence electrons. They are used to bond, which determines its properties.

Vector A has a magnitude of 50 units and points in the positive x direction. A second vector, B , has a magnitude of 120 units a
Alex Ar [27]

A) Vector A

The x-component of a vector can be found by using the formula

v_x = v cos \theta

where

v is the magnitude of the vector

\theta is the angle between the x-axis and the direction of the vector

- Vector A has a magnitude of 50 units along the positive x-direction, so \theta_A = 0^{\circ}. So its x-component is

A_x = A cos \theta_A = (50) cos 0^{\circ}=50

- Vector B has a magnitude of 120 units and the direction is \theta_B = -70^{\circ} (negative since it is below the x-axis), so the x-component is

B_x = B cos \theta_B = (120) cos (-70^{\circ})=41

So, vector A has the greater x component.

B) Vector B

Instead, the y-component of a vector can be found by using the formula

v_y = v sin \theta

Here we have

- Vector B has a magnitude of 50 units along the positive x-direction, so \theta_A = 0^{\circ}. So its y-component is

A_y = A sin \theta_A = (50) sin 0^{\circ}=0

- Vector B has a magnitude of 120 units and the direction is \theta_B = -70^{\circ}, so the y-component is

B_y = B sin \theta_B = (120) sin (-70^{\circ})=-112.7

where the negative sign means the direction is along negative y:

So, vector B has the greater y component.

There are two possibilities for final stage of extremely massive stars. The first is a
makkiz [27]

Answer: Black hole.

Explanation:

As the massive star "compacts" under its own gravity, it triggers a massive supernova, after this point the remains of the star can become a neutron star, which is a very compact star made primarily, as the name says, of neutrons. The other possibility is a black hole, which is a finite region of space wherein it's interior there is a big concentration of mass, which creates a gravitational field strong enough that there is no particle that can escape it.
