Answer and explanation;

In general, you can choose when, where, and how to exercise. Each of these choices can either positively or negatively affect your safety during physical activity.

To play it safe and reduce your risk of injury: Begin your exercise program slowly with low-intensity exercises. Wear appropriate shoes for your activity. Warm up before exercising, and cool down afterward. Pay attention to your surroundings when exercising outdoors.

If a quasar is moving away from us at v/c = 0.8, what is the measured redshift?
Delicious77 [7]

Answer:

The measured redshift is z =2

Explanation:

Since the object is traveling near light speed, since v/c = 0.8, then we have to use a redshift formula for relativistic speeds.

z= \sqrt{\cfrac{c+v}{c-v}}-1

Finding the redshift.

We can prepare the formula by dividing by lightspeed inside the square root to both numerator and denominator to get

z= \sqrt{\cfrac{1+\cfrac vc}{1-\cfrac vc}}-1

Replacing the given information

z= \sqrt{\cfrac{1+0.8}{1-0.8}}-1

z= \sqrt{\cfrac{1.8}{0.2}}-1\\z= \sqrt{9}}-1\\z=3-1\\z=2

Thus the measured redshift is z = 2.
