A hockey puck with a mass of 0.34 kg is traveling to the right along the ice at 30 m/s. It strikes a second hockey puck with a mass 0.22 kg. The first hockey puck comes to rest after the collision. What is the initial momentum of the system? (Round your answer to the nearest tenth.) Please show work by identifying the known variables with units, and unknown variable with a question mark. (25 Points) Place known variables with units, and unknown variable/s to the Intial Momentum Formula. (25 Points) Write the math statements to prove your math claim.(25 points) Be accurate with your math claim by writing the number with appropriate units. (25 Points)

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
