I believe that the answer is C. Hope this Helps:)))
Answer:
0.025 Meters a second, or 0.025 m/s
Explanation:
So, if we take the information that we know, 1) The wall is 2 meters thick, and 2) it took a total of 0.05 seconds to travel all the way. So, to get our answer, lets divide 0.05 by 2. That lands us with 0.025! This answer makes sense, because we know that sound travels quickest in solids, (Due to sound-waves being a mechanical longitudinal wave, and solids have the densest particle formations, allowing the sound wave to travel swiftly compared to liquids and gases, in which the particles are more spread out.)
Well it would not be c as it wouldn't be a transmitter. Since it's a power plant it wouldn't be Transmitter, and heated water makes steam it has to be B Steam, Turbine.
Answer:
Speed,
Explanation:
Given that,
Radius of the neutron stare, R = 20 km = 20,000 m
Time taken by the Neutron star to rotate, t = 1 s
We need to find the speed of a particle on the star's equator. The total distance covered divided by total time taken is called speed of an object. Here,


v = 125663.70 m/s
or

So, the speed of a particle on the star's equator is
. Hence, this is the required solution.
