Block X of mass mo is at rest at the top of a ramp, and the block's center of mass is at a height H above the ground. Block X is then released from rest, and it slides down the ramp and collides with block Y of mass mo, which is initially at rest and has its center of mass at a
height h above the ground. At the moment before the collision, block X has a speed of vo. After the collision, block Y travels such that it
lands at point P.
Consider the block X-block Y system from the moment in time that block X is released from rest to the moment immediately after block X
collides with block Y. Which of the following claims best describes the system?
А
Because the total momentum of the system does not remain constant, the system is open.
B
Because the total kinetic energy of the system does not remain constant, the system is open.
с
Because the total momentum of the system remains constant, the system is closed.
D
Because the total kinetic energy of the system remains constant, the system is closed.

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

How will the system respond to a temperature increase?
