The kinetic energy, k, of an object varies jointly with its mass, m, and the square of its velocity, v. the mass of an object staysthe same, but the velocity of the object is halved. how is the kinetic energy of the object affected?
the kinetic energy is quartered.
the kinetic energy is halved.
the kinetic energy is doubled.
the kinetic energy is quadrupled.

The answer is harsh laws are needed to control the society

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
