Cosmic rays are highly energetic particles which can travel at great speeds through outer space. a typical speed for a cosmic ray is 1.29 x 10^8 m/s. what is this speed converted to km/hr (kilometers per hour)? a. 1.29 x 10^5 km/hr b. 35.8 km/hr c. 7.74 x 10^6 km/hr d. 4.64 x 10^8 km/hr

Speed of the cosmic rays,

Explanation:

It is given that, Cosmic rays are highly energetic particles which can travel at great speeds through outer space.

The speed of the cosmic rays,

We need to convert the speed of cosmic rays to kilometers per hour. We know that :

1 kilometers = 1000 meters

1 hour = 3600 seconds

On solving the above expression,

or

So, the speed of the cosmic rays is . Hence, this is the required solution.
