B. I think is the correct answer
Oxidation number is the charge.
<span>assuming the pitch is 100yards long, the player runs 100yards to the other goal then a further 50 yards back to the 50-yard line. So he/she runs 150yards in 18s
150/18 = 8.33yards per second average speed.
Initial velocity = 0, average velocity =8.33
Vav = (Vinitial+Vfinal)/2
Vav = 4.16m/s</span>
To solve this problem it is necessary to apply the concepts related to Kinetic Energy, specifically, since it is a body with angular movement, the kinetic rotational energy. Recall that kinetic energy is defined as the work necessary to accelerate a body of a given mass from rest to the indicated speed.
Mathematically it can be expressed as,

Where
I = Moment of Inertia
Angular velocity
Our values are given as

A revolution is made every 4.4 seconds.


If the angular velocity is equivalent to the displacement over the time it takes to perform it then


Replacing at our previous equation we have,



Therefore the kinetic energy is equal to 
Answer:
False.
Explanation:
Mechanical waves require a medium in order to transport their energy from one location to another.
