How fast should your spacecraft travel so that clocks on board will advance 10.7 times slower than clocks on Earth?

The value is  

Explanation:

From the question we are that

  The number by which the clock on the spacecraft should be slower than that on the earth is  

 Generally from the time dilation relation given by Albert Einstein we have that

Here is the time on earth

        is the time on the spacecraft

        v is the speed of the spacecraft

        c is the speed of light with value  

So

Given that

So

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

the gas collects in coils that then becomes a liquid that then flows through the coils inside the refrigerator
