What is the quantity used to measure an object's resistance to changes in rotational motion?

Explain the comparisons between nature and packingtown that appears on pages 81 and 82 answer

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)

Amaterial that provides resistance to the flow of electric current is called a(an) (1 points)
