A roll of paper is rolled to the ground, leaving paper behind when rolling. The remaining paper remains stationary on the floor. The roller was given a starting speed of V = 2.4 m / s. The initial radius of the roller is R = 1 m. When the radius of the roller is r = 0.6 m, find the V speed of the roller in m / s. Assume that roll rolls do not slip and gravity acts on the roll. Let's also assume that the mass distribution of the paper in the roll is homogeneous. (Get G = 10 m / s ^ 2)

The sample with the lowest specific heat capacity will have the greatest temperature increase. in this case, it would be platinum.

The purpose of a lab is to do your "expirements" the importance of the topic is so you can now what the story is about and the last one is because no one is me with my question ( what is 3 over 4 x - 9 = 27 maybe you can )

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
