The ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.
<h3>What is the
rotational kinetic energy of a sphere?</h3>
The rotational kinetic energy of the sphere is directly proportional to the square of angular acceleration.
Where,
= rotational inertia of sphere = 2/5MR²
Where is the mass of the sphere and is the radius of the sphere,
ω = angular acceleration of sphere = V/R
Where is the speed of the sphere.
So,
K = 1/2 × 2/5MR² × V²/R²
K = MV²/5
The translational kinetic energy of the sphere,
The total kinetic energy of the sphere,
So,
Thus the Ratio of rotational kinetic energy to total kinetic energy,
Therefore, the ratio of the rotational kinetic energy about the center of the sphere and the total kinetic energy of the sphere is 2/7.

Answer:
Option B seems to be the appropriate choice,
Explanation:
The given question is incomplete. Please find the attachment of the complete question.
- From either the principle or law of the Coulombs, there would have been either pressure (force) through attachment or repulsion amongst charges.
- It is evident from the analysis presented that perhaps the bee becomes positively (+) charged and would have been drawn either by negatively (-) charged roots of the plants or stem.
As a consequence, the vegetation is electric current polarized because as activated bee pursued.
When the velocity increases, then the acceleration will be positive and when the velocity decrease then the acceleration will be negative.
During the first hour, the velocity was 70 mph and during the seconds hour the velocity was 60 mph. Hence, the velocity decrease in the seconds hour. So, the acceleration will be negative during the second hour.
Now, during the third hour the velocity increases as it is 80 mph. Hence, the acceleration will be positive during the third hour.
'Newton-second' is dimensionally equivalent to 'kilogram-meter/second'.
