A cylinder is rolling along the ground at 2` m/s. It comes to a hill and starts going up. Assuming no losses to friction, how high does it get before it stops

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

In atoms, the electron carries a negative elementary or unit charge; the proton carries a positive charge. the two types of charge are equal and opposite. in an atom of matter, an electrical charge occurs whenever the number of protons in the nucleus differs from the number of electrons surrounding that nucleus.

Umm, its not your fault, and its because some things in your brain.

The rift will widen between the plates; new crust will form on either side of the rift, water from the ocean will rush in, and eventually, iceland will split apart.hope this is !
