The clay-turntable system's rotational inertia after strike will be (2/3)mR². Then the correct option is C.
<h3>What is rotational inertia?</h3>
The summation of the product of the mass of each particle with its square of the distance from the rotational axis is the moment of inertia, which is the amount denoted by the body resistant angular acceleration.
A turntable with mass m, radius R, and rotational inertia (mR²)/2 initially rotates freely about an axis through its center at constant angular speed with negligible friction.
A piece of clay, also of mass m, falls vertically onto the turntable and sticks to it at point P, a distance R/2 from the center of rotation.
Then the clay-turntable system's rotational inertia after strike will be

An appeal.
A person convicted may file a petition for review with a higher court on certain grounds (I.e., error of fact, error of law, etc.). This is usually considered an appeal as of right. The party can automatically bring an appeal to the appellate court by filing a notice of appeal. The higher court may reverse the decision of the lower court in part or in whole or may let the decision stand. In certain instances the higher court may send the case back to the trial court for further review.
Appeals made to the US Supreme Court require a loss at the federal court of appeals level and the filing of a Writ of Certiorari. These appeals are considered discretionary appeals in that the Supreme Court has the discretion to decide whether they will hear the appeal or not.
Answer:
- Last choice: <u><em>The net force on an object applied over a distance</em></u>
Explanation:
When several forces act act over an object, the vectorial force is call net force.
Every force can do work, as the work () is the product of the force () and the parallel displacement (<em>D</em>) caused by such force.
When several works are done on a object the <em>net work</em> is the sum of all the works done by the forces acting on the object.
Such net work is equivalent to a work done by the <em>net force</em> over the net parallel displacement, which is the distance from the starting point and the ending point.
Hence, the net work can be determined as <em>"The net force on an object applied over a distance", </em>which is the last statement.
