A metal sign for a car dealership is a thin, uniform right triangle with base length b and height h. the sign has mass m.
Nesterboy [21]

(a) The moment of inertia of the sign for rotation about the side of length h is 1.24 kgm².

(b) The kinetic energy of the sign when it is rotating about an axis is 141.37 J.

<h3>Moment of inertia of the triangular sign</h3>

The moment of inertia of the sign for rotation about the side of length h is calculated as follows;

I = 2 x ¹/₃M(b/2)²

I = 2 x ¹/₃Mb² x ¹/₄

I = ¹/₆Mb²

I = ¹/₆ x 4.4 x 1.3²

I = 1.24 kgm²

<h3>Rotational kinetic energy of the ball</h3>

K.E(rot) = ¹/₂Iω²

where;

  • ω is angular speed = 2.4 rev/s = 2.4 x (2π rad)/s = 15.1 rad/s

K.E(rot) = ¹/₂(1.24)(15.1)²

K.E(rot) = 141.37 J

What is the difference between a mechanical wave and an electromagnetic wave? A mechanical wave travels through empty space, whi
sertanlavr [38]

Answer: The correct answer is "A mechanical wave travels through matter, while an electromagnetic wave travels through empty space".

Explanation:

The difference between a mechanical wave and an electromagnetic wave are as follows:

Electromagnetic waves are produced by the vibrations of the charged particles while the mechanical waves are caused by the wave amplitude.

Electromagnetic wave does not need medium while the mechanical wave need medium to travel. Mechanical wave can travel in solid, liquid and gas. Electromagnetic wave travels in vacuum.

Therefore, a mechanical wave travels through matter, while an electromagnetic wave travels through empty space.

Calcula la energia potencial de Tamara que tiene una mas de 50kg y se encuentra, 80 metros arriba en el borde de un edificio
Ilya [14]

Responder:

39200 J

Explicación:

Dado:

Masa de Tamara (m) = 50 kg

Altura a la que se encuentra Tamara (h) = 80 m

Aceleración debido a la gravedad (g) = 9.8 m / s²

La energía potencial de un objeto de masa 'm' ubicada a una altura 'h' sobre el suelo se da como:

U=mgh

Ahora, conecte los valores dados y resuelva la energía potencial. Esto da,

U=50\times 9.8\times 80\\\\U=39200\ J

Por lo tanto, la energía potencial de Tamara ubicada a una altura de 80 m es 39200 J.
