3.why does energy as heat move away from the tropics and toward the pole in the global weather system? 5. A student is reading about predicted upcoming El Niño event. In what way could the student expect to see the global weather patterns change?

Answers

There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
Radiation is the transfer of heat regardless of the presence of atoms or particles.

Well since this question was asked years ago, I do believe that there is more solar energy at the equater and less at the poles.

Explanation:

A student has the following equipment - copper wire, nail made of iron,a battery, paperclips.How can he make an electromagnet and use it to separate a mixture of small pieces of copper and iron?

please help

Answers

The first step would be to create an electromagnet. You can create an electromagnet by winding a copper wire around the nail, the connect both ends to the battery. A current would start flowing around the nail through the wire, creating an electromagnet with its own magnetic field. Next, bringing the electromagnet to the mixture of copper and iron would slowly attract the pieces of iron (as copper is weakly magnetic). Do this slowly and the iron pieces would all slowly be separated from the copper pieces.

According to the law of refraction, light passing from air into a piece of glass at an angle of 30 degrees will cause the light to

Answers

Answer:

bend toward the normal line

Explanation:

When light passes from a less dense to a more dense substance, (for example passing from air into water), the light is refracted (or bent) towards the normal. In your question the light is moving from rarer to denser medium

Final answer:

Upon refracting from air to glass, light will bend towards the normal line, reducing the angle of incidence due to the principle of Snell's Law, which governs how light refracts between media. However, the exact refracted angle cannot be determined without the refractive indices of air and glass.

Explanation:

According to the Law of Refraction, also known as Snell's Law, light changes direction when it passes from one medium to another due to a change in speed, which is determined by the mediums' refractive indices. When light passes from air (a medium with a lower refractive index) into glass (a medium with a higher refractive index), it bends towards the normal line, the imaginary line perpendicular to the surface at the point of incidence.

Given that the angle of incidence is 30 degrees, following the formula of Snell's law: n₁ sin θ₁ = n₂ sin θ₂ where n₁ and n₂ are the refractive indices of air and glass, and θ₁ and θ₂ are the angles of incidence and refraction, we could solve for θ₂ which will be the angle of refraction in glass. However without information of refractive indices of air and glass, an exact angle cannot be determined.

In summary, the light ray will bend towards the normal upon entering the glass, hence decreasing the angle of incidence, according to the Law of Refraction or Snell's Law.
