Increasing which of the following would increase the magnetic force between the permanent magnet and the coil? A. Transformer B.

Circuit C. Current D. Generator
Physics
1 answer:
Gnoma [55]3 years ago
7 0

For this one, all you really need to do is eliminate any answers
that are absurd or meaningless.

You can't increase a transformer.
You can't increase a circuit.
You can't increase a generator.

When the <em><u>current</u></em> through a coil of wire increases, the magnetic field
around the coil increases, so there would be more magnetic force
between the coil and a permanent magnet.

Explain the change of frequency of the wave if the tension of the string is increased​
jek_recluse [69]

Answer:

Increasing the tension on a string increases the speed of a wave, which increases the frequency (for a given length). Pressing the finger at different places changes the length of string, which changes the wavelength of standing wave, affecting the frequency.

In complete sentences describe the energy flow between the Sun, the Earth, and space
agasfer [191]
Answer: The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
Explanation:
The amount of incoming energy from the Sun decides the weather and climate of earth. If the energy that is incoming and outgoing on the earth, then climate is in equilibrium. The balance is depending on the scattering, absorption, reflection and transformation of energy.
The energy from sun passes through space and reaches the earth’s surface. On reaching surface, the solar energy warms the atmosphere releasing heat energy which gets transferred throughout the planets system by radiation, conduction and convection. Conduction happens in the atmosphere within first several millimeters close to the surface. This heated air expands as it is dense and rises causing transfer of heat to atmosphere through convection process. It results in formation of clouds.
The radiant energy from sun is transmitted via space in form of invisible waves. But much of the suns radiant energy, is transmitted back to atmosphere. The objects on earth like land, plants, animals absorb radiant energy as heat of which one third gets re-radiated back to atmosphere that is absorbed by carbon dioxide and water vapor. The atmosphere radiates heat energy back to earth increasing the earth temperature. This trapping of radiation is greenhouse effect.
The thermal energy obtained by convection currents are responsible for wind, cloud formation, and weather formation. The hydrosphere that comprises of 70% of earth’s surface absorbs solar energy.
On the basis of the above explanation is:
The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.

Which statements about a neutral atom are correct? Select all that apply. (1) A neutral atom is composed of both positively and
Bad White [126]

Answer:

(3) The electrons are attracted to the positively charged nucleus.

(4) Positively charged protons are located in the tiny, massive nucleus.

(6) The negatively charged electrons are spread out in a "cloud" around the nucleus.

Explanation:

An atom is the basic particle in which a matter is formed. It can either be charged or neutral. When it losses or gains an extra electron, it becomes charged, an ion. While a neutral atom is an atom which has no charge, because it has the same number of electrons and protons. The protons are located in the tiny massive nucleus of the atom, while the electrons are in orbits or cloud around the nucleus.
