Radio waves are electromagnetic waves and as such travel at the speed of light. Waves emitted a century ago would be 100 hundred light years away. A light year is the distance light travels in one year. In one year light travels about 5.9 trillion miles. therefore the waves traveled about 590 trillion miles in a century.
An object moving in a circle is accelerating, even if it moves with a constant speed because the velocity changes.
<u>Explanation:</u>
The direction of an object changes constantly during its movement in circle at a constant speed. As the direction changes it results in changing the velocity of that object. This happens since velocity has direction and magnitude.as it is vector quantity.
An object will have acceleration only if a resultant force is acting on that body. When an object is moving in a circle, this resultant force is the centripetal force that is acting towards the center of the circle.
