The Sun's energy reaches the earth by _____. conduction convection radiation fusion

Answers

Answer 1

Answer: When heat or any other kind of energy move from one place
to another, conduction and convection need some material stuff
along the way, otherwise they don't happen.

There is no material stuff between the Sun and the Earth, so
the Sun's energy reaches us by radiation.

Answer 2

Answer:

The Sun's energy reaches the earth by Radiation

Further explanation

Heat is the energy transfer of an object with the environment or other objects because of the temperature difference between the two.

Heat moves from high-temperature objects to low-temperature objects

The process of heat transfer has 3 types

1. Conduction, which is the transfer of energy that requires an intermediate medium and without the transfer of particles

2. Convection is the transfer of energy due to the movement of the particles

3. Radiation is the transfer of energy without an intermediate medium / through vacuum

Energy from sun to earth through its atmosphere is not through conduction because the atmosphere is a bad conductor. Whereas convection is not possible because the earth must be heated first. And conduction and convection cannot pass through vacuum

Heat transfer from the sun occurs because its energy is carried in the form of electromagnetic waves

The correct answer is letter c. Enthalpy (H). Entrophy means the measure of the degree of disorder. Gibbs energy formulated by Josiah Willard Gibbs and it is the energy associated with a chemical reaction to do work.Fusion is the combining light nuclei into a heavier nucleus.

The magnetic north pole changes location but the geographic north pole does not true or false

Answers

The North Magnetic Pole is the point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, it will point straight down). There is only one location where this occurs, near (but distinct from) the Geographic North Pole and the Geomagnetic North Pole. So yes true

Which of the following universal forces is the weakest? A) electric
B) gravitational
C) magnetic
D) strong nuclear

I also need some explanation for this one

Answers

Answer:

Option (B)

Explanation:

The gravitational force is usually defined as the force of attraction that occurs due to the presence of the object's mass. The mass of the object and the force of gravity is directly proportional to each other. At the atomic as well as at the subatomic levels, this gravitational force of gravity is comparatively so weak because the masses of these atoms, subatomic particles are extremely very small. This force has a strength of about 10^-40 and this far smaller in comparison to the strength of electromagnetism.

On the other hand, the other universal forces such as the electric force, magnetic and strong nuclear force are very much stronger than the gravitational force. The nuclear force is strongest of all, where it is 100 times stronger than the electromagnetic force and approximately 10^36 times stronger than the gravitational force.

Thus, the correct answer is option (B).

Well, electric and magnetic are actually the same in nature (as basic force in the Universe). The four, in decreasing order of strength, are:
Strong nuclear, Weak nuclear, Electric/Magnetic (in roughly the same range) and Gravitational (much weaker than Electric/Magnetic -- a magnet less than 1 kg beats Earth which is quite a lot of gigatons, roughly)
