How fast must an object move before its length appears to be contracted to one-half its proper length?
notsponge [240]

The object must move with the speed of \frac{\sqrt{3} }2} times to approximately seeing that it is contracted to exactly half of its actual length.

<h3>How is this calculated?</h3>

The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:

\frac{L}{L'} = \sqrt{(1) - (\frac{v}{c})^{2}

Here, v is the current speed m/s

c is the speed of light in m/s

L' is the length of the object at rest in m

L is the length of the object at the current speed in m

Now we know that

\frac{L}{L'}= \frac{1}{2} and \frac{v}{c} = r then,

\frac{1}{2} = \sqrt{1 - r^{2} }\\\frac{1}{4} = 1 - r^{2}\\r^{2} = \frac{3}{4}

Hence, r = \frac{\sqrt{3} }{2}

Therefore, the answer is the object must travel at a speed of \frac{\sqrt{3} }{2} times the lightspeed to be contracted to one-half its proper length.

Cuáles fueron los factores que influyeron negativamente en los resultados de las políticas de salud _XIX y cuáles permanecen act
Solnce55 [7]

La respuesta correcta para esta pregunta abierta es la siguiente.

Desafortunadamente, no especificas a qué país te refieres.

Cada país tienen sus propias políticas y leyes en materia de salud.

A falta de esta importante información, lo que podemos hacer con tal de ayudarte es responder en términos generales.

Los factores que influyeron negativamente en los resultados de las políticas de salud del siglo XIX es que realmente no existió un programa de salud pública bien establecido, en donde el gobierno tuviera la visión de invertir en la apropiada infraestructura médica y hospitalaria para enfrentar crisis en materia de salud. Los políticos, ni tuvieron la visión ni la iniciativa para crearlo.

De ahí que, y en base a la cultura del país y su forma de ser, actualmente permanece esa errónea idea de no contar con un verdadero programa de inversión, investigación y desarrollo en materia de salud pública.

Tan no existe, que desde el año pasado y debido al problema de la pandemia, la mayoría de países Latinoamericanos ha vivido en una permanente crisis sanitaria en donde los pocos hospitales que pudieran estar equipos para atender a los enfermos se han visto desbordados por la cantidad de pacientes y la poca infraestructura médica para poderlos atender.
