Answer:
a). is lower in elevation than city B
Explanation:
Temperature of a place greatly varies with height or altitudes.
As we go higher the atmospheric pressure becomes less and the temperature decreases. We feel cold at higher altitude places and relatively hot at places of lower elevation. Therefore City A which is at lower elevation has greater annual temperature range than the temperature range of city B although they are located at the same latitude. City A is at lower altitude and City B's elevation is higher. So City A has higher temperature range than city b.
The copper is a conductor and the rubber is an insulator. Conductors allow electricity to be transmitted freely while insulators prevent most of the current from transmitting. The outer electrons of the conductor's atoms are not very stable and are able to freely move around the material. In a material such as copper, the valence electrons are essentially free and strongly repel each other. The atoms of insulators such as rubber, hold tight to their outer electrons which prevents electricity from flowing freely through.
Yes it is.
N₂ + 3H₂ ⇒ 2NH₃
Answer:
lower
Explanation:
The lower the value of the coefficient of friction, the lower the resistance to sliding.
The coefficient of friction is the ratio of the frictional force and the normal force pressing two surfaces in contact together.
U = 
U is the coefficient of friction
F is the frictional force
N is the normal force
We see that coefficient of friction is directly proportional to frictional force.
Newton’s third law of motion says that every time there is an ____action_______ force, there is also a ______reaction________ force that is ___equal________ in size and acts in the ___opposite____________ direction. This means that forces ALWAYS occur in __pairs________.
