Answer:
A. Radio waves.
Explanation:
Electromagnetic radiation is defined as the waves (or photons - packets of energy) of the electromagnetic field, propagating through space, carrying electromagnetic radiant energy.
Examples of electromagnetic radiation are : infra red, visible light, ultraviolet light, gamma rays, radio waves etc.
It depends for what purpose the audience have gathered and where they are.
I am going to have to say:
B. Physical Appearance as it fits in all or most audience categories.
Answer:
The length of the sling is increased and the linear velocity of the stone stays the same.
Explanation:
Centripetal acceleration is given by
where <em>v</em> is the linear velocity and <em>r</em> is the radius of motion.
In terms of the angular velocity, <em>ω</em>
<em />, since
From the relation, is directly proportional to the square of the velocity and inversely proportional to the radius.
Hence, an increase in linear velocity results in an increase in the centripetal acceleration if the radius is kept constant. A decrease in the radius also causes an increase of the centripetal acceleration.
