the answer for 0.429m to mm is 429
They make up a Complex Machine.
Answer:
Either B or D. The answer itself is 2.
Explanation:
The equation for the kinetic energy would be 1/2*mv^2.
When m is doubled, we can plug in 1 and 2 to compare our answers.
Plugging in 1 for mass would give us the answer 1/2*v^2.
Plugging in 2 for mass would give us v^2. This means that the velocity was multiplied by 2, meaning that the answer is it is multiplied by 2.
I am not sure which answer is correct since there seems to be two answer choices with 2 in it, but the answer is either B or D (I will call it ABCD because I do not want to cause confusion by saying 2 multiple times).
Red shift of star is defined as its wavelength. Star with smaller red shift have smaller wavelength, while star with greater red shift have greater wavelength. We can say that, Star X have smaller wavelength, while star Y have greater wavelength.
