Albert stands on a frictionless turntable, holding a bike wheel. both albert and the wheel are initially stationary. albert gives the bike wheel a good spin, and it begins rotating counterclockwise. if the bike wheel has a final angular momentum of one unit, counterclockwise, what is the final angular momentum had by the re of the system (i. e. albert and the turntable)? one unit, counterclockwise zero units one unit, clockwise two units, counterclockwise two units, clockwise albert flips the bike wheel upside down, so that it is now spinning the other way and has one unit of angular momentum in the clockwise direction. by how much does the angular momentum of albert (plus turntable) change during the process of flipping the wheel? one unit, counterclockwise two units, clockwise zero units one unit, clockwise two units, counterclockwise

When the velocity of an object is doubled, by what factor is its momentum changed? by what factor is its kinetic energy changed? a) the momentum is zero. b) the momentum is not zero. c) difficult to say.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
