Question

10. if 1 is subtracted from the last digit of each of the above numbers the sum of the digits of how many of them are prime numbers?

Answer 1

Kinetic energy is the energy of moving objects, including objects that are rotating. The kinetic energy of a rotating object depends on the object's angular (rotational) velocity in radians per second, and on the object's moment of inertia. Moment of inertia is a measure of how easy it is to change the rotation of an object. Moments of inertia are represented with the letter I, and are expressed in units of kg∙m2. The unit of kinetic energy is Joules (J). In terms of other units, one Joule is equal to one kilogram meter squared per second squared ().
