The parallel axis theorem relates Icm, the moment of inertia of an object about an axis passing through its center of mass, to I
erma4kov [3.2K]

Answer:

Part a)

I_{end} = \frac{mL^2}{3}

Part b)

I_{edge} = \frac{2ma^2}{3}

Explanation:

As we know that by parallel axis theorem we will have

I_p = I_{cm} + Md^2

Part a)

here we know that for a stick the moment of inertia for an axis passing through its COM is given as

I = \frac{mL^2}{12}

now if we need to find the inertia from its end then we will have

I_{end} = I_{cm} + Md^2

I_{end} = \frac{mL^2}{12} + m(\frac{L}{2})^2

I_{end} = \frac{mL^2}{3}

Part b)

here we know that for a cube the moment of inertia for an axis passing through its COM is given as

I = \frac{ma^2}{6}

now if we need to find the inertia about an axis passing through its edge

I_{edge} = I_{cm} + Md^2

I_{edge} = \frac{ma^2}{6} + m(\frac{a}{\sqrt2})^2

I_{edge} = \frac{2ma^2}{3}

What is transmitted by all waves
Nesterboy [21]
<h3><u>Answer;</u></h3>

Energy

<h3><u>Explanation;</u></h3>
  • A wave is a transmission of disturbance from one point to another. All waves involve transmission of energy from one point called the source to another point.
  • <em><u>Waves describes various ways in which energy can be transferred from a point source.</u></em>
  • <em><u>In electromagnetic waves</u></em><em>, for instance, </em><em><u>energy transmission occurs as a result of vibrations of electric and magnetic fields</u></em><u>.</u>
  • <u><em>In mechanical waves energy transmission is as a result of vibration of particles in the medium used</em></u>. For example in sound waves, energy is transferred through vibration of particles of air or particles of a solid or medium through which sound travels through.

goblinko [34]

Answer:

Explanation:

initial velocity u = 32.7 m /s

final velocity v = 50.3 m /s

displacement s = 44500 m

acceleration a = ?

v² = u² + 2 a s

50.3² = 32.7² + 2 x a x 44500

2530.09 = 1069.29 + 89000a

a .016 m /s²

time taken t = ?

v = u + at

50.3 = 32.7 + .016 t

t = 1100 s
