Answer: An object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.

Explanation: To find the answer, we need to know more about the kinetic and potential energies.

<h3>What is kinetic energy of a body?</h3>
  • Kinetic energy is a form of mechanical energy possessed by a body by virtue of its motion.
  • Kinetic energy of a body of mass m moving with a velocity v is given by,

                           KE=\frac{1}{2}mv^2

<h3>What is potential energy?</h3>
  • Potential energy is a form of mechanical energy possessed by a body by virtue of its position in the field or configuration.
  • PE is always associated with a conservative force.
  • There cannot be potential energy due to frictional or viscous forces.

Thus, we can conclude that, an object at rest has no kinetic energy, but it may have potential energy resulting from its location or structure.

Answer:

c. Include ancillary clinical and medical staff in the process

Explanation:

The best way to achieve goal i.e. improve clinical documentation to support the quality of care, data quality, and HIM coding accuracy will be to include the clinical and medical staff in the process since it will train them and motivate them which is the best approach to make everyone understand the importance of the program.

If the mass of a wheel is increased by a factor of 7 and the radius is increased by a factor of 15, by what factor is the moment
inn [45]

Answer:

The moment of inertia will be increased by a factor of 1575

Explanation:

Let the moment of inertia of a wheel be given as;

I = \frac{1}{2} mr^2\\\\

where;

I is the moment of inertia of the wheel

m is mass of the wheel

r is radius of the wheel

when the mass is increased by a factor of 7 and the radius is increased by a factor of 15

I_1 = \frac{1}{2}mr^2\\ \\I_2 = \frac{1}{2}(7m)(15r)^2\\\\I_2 =  \frac{1}{2}(7m)(225r^2)\\\\I_2 = 7\times 225[\frac{1}{2}(mr^2)]\\\\I_2 = 1575[\frac{1}{2}(mr^2)]\\\\Recall, \frac{1}{2}(mr^2) = I_1 \\\\I_2 = 1575 I_1

Thus, the moment of inertia will be increased by a factor of 1575
