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.

Christian Ethics considers which of the following to be an important virtue or character trait that is relevant to the position

andreev551 [17]

Answer:

Christian Ehics considers<u> integrity</u> as a an important virtue or character trait that is relevant to the position one takes on drilling for oil in the Arctic.

Explanation:

Christian ethics is the study of ethics in the field of theology. It stablishes good and wrong actions, this means it considers the impact of people´s decisions. Values for instance are guideliness to determine if and actions is considered right or wrong. Ethics considers the effect a possible action may have, the impact in other or in this case in the environment.

Integrity is definied by a person who does not take decisions if it is going to harm others. In this case drilling for oil in the Artic will definetely have impact on the enviroment, animals and plants. Even if oil generates money and has many uses, it would have harmful effects on the environment.
