Areas with mountains are warmer than other areas at the same latitude.

Answers

Answer:

Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. A coastal climate is usually mild. ... Farther inland, the climate is influenced by cold or hot air from the land.

Explanation:

Hopefully its correct!

The statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.

At high altitudes, the temperature is colder than in areas closer to the sea level.

At higher altitudes, there are fewer air molecules in a specific surface area than in the same area at lower levels. Thus, as air rises, the air pressure decreases.

This lower air pressure causes the temperature to be colder at high altitudes than at sea level.

In conclusion, the statement 'areas with mountains are warmer than other areas at the same latitude' is FALSE.

Why is it important for the path of a circuit to be circular?

Answers

Answer:

When the platform rotates, the rotating mass will travel in a circular path due to the force exerted on it by the string (by way of the tension in the spring). Since it is not possible to have an instantaneous readout of this tension force while the platform is rotating, an indirect measurement of this force will be made using the weight of the static mass as shown and explained below.

If the circuit's path wasn't curcular, I don't think it'll function very well.

What is one way that an electric field is different from a magnetic field?

Answers

Answer:

The one of the major difference between the magnetic and electric field is that the electric field induces around the static charge particle which is either negative or positive, whereas the magnetic field produces around the poles (i.e., the north and south pole) of the magnet

Explanation:

Difference Between Electric Field And Magnetic Field. Magnetic field is an exerted area around the magnetic force. It is obtained by moving electric charges. The direction of the magnetic field is indicated by lines. While the electric fields are generated around the particles which obtains electric charge.
