Atoms of different elements can join together in arrangements to produce a variety of substances that are found on Earth. There are more than a hundred
known elements. Which of the following best describes these elements?
F. Most of these elements are metals.
G. Most of these elements are metalloids.
H. Most of these elements are nonmetals.
I. Most of the these elements are noble gases.

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)

Consider an air-filled charged capacitor. how can its capacitance be increased?

If 130 j of energy were added to 1 kg of each of the samples listed in the answer choices, which would experience the greatest temperature increase
