Answer:

The correct answer is:

A. straightening the wire, because the number of turns of the wire around the iron core is directly proportional with the strength of electromagnet.

and,

C. decreasing the voltage is correct, by decreasing the voltage, the current will decrease and this leads to weaker electromagnet.

Explanation:

Simply, the electromagnet is used to convert electric energy to magnetic energy.

Basic idea:

The basic idea of the electromagnet is, when the electric current passes through a wire it creates a weak magnetic field

Components of simple electromagnet:

Battery: source of electricity
Electric wire: the electric current passes through it
Iron core: will convert to temporary magnet

The strength of electromagnet is simply defined by the strength of magnetic field that synthesized by the electric current.

Factors affects strength of electromagnet:

Strength of current: by increasing the current that passes through the wire the magnetic field will increase, ( so decreasing the voltage will decrease the current produced and will decrease the strength of electromagnet)

Number of loops or number of turns of the wire: the more the number of turns, the more the electric field produced, (so straightening the wire will decrease the magnetic field induced and decrease the strength of electromagnet).

The metal core: iron core makes stronger electromagnet.

Decreasing the resistance: this will increase the current produced and will increase strength of electromagnet.

The answer is mutualism or letter a. The tick birds ride on the buffalo’s back and eats the tick from its body. This relieves the buffalo from the insects that suck on its blood. The birds have a food source while the buffalo has someone to eat away at the ticks.

1. how are positive ions formed (what is gained or lost)? use potassium (k) as an example. how many protons and electrons does a

Levart [38]

Positive ions are formed when electrons are lost, for example, Potassium ion, K⁺ is formed when a Potassium atom, K losses one electron. A neutral atom of Potassium (K) has 19 protons and 19 electrons, and a positive ion of Potassium (K⁺) has 19 protons and 18 electrons.

Ions are charged particles formed when neutral atoms loss or gain electrons. When electrons are lost, positively charged particles called cations are formed, and when electrons are gained, negatively charged particles called anions are formed. Electropositive elements are more likely to form cations. Potassium (K) losses one electron in order to obtain a stable configuration, forming Potassium ion (K⁺).

For all neutral atoms, the number of protons is always equal to the number of electrons. The number of protons is the same as the atomic number. Potassium (K) has an atomic number of 19, thus it has 19 protons. Since Potassium (K) atom is a neutral atom, it will also have 19 electrons.

However, Potassium ion (K⁺) has lost one of its electrons, so it will have 18 electrons instead of 19. Therefore, Potassium (K) has 19 protons and 19 electrons, while Potassium ion (K⁺) has 19 protons and 18 electrons.

mars1129 [50]

Answer:

A) Golgi tendon organ.

Explanation:

A tendon organ or neurotendinous organ or Golgi tendon organ is a mechanoreceptor located at the insertion point of the skeletal muscle to the tendon that is at the myotendinous junction.

The Golgi tendon organ is composed of the collagenous muscle fibres which contain the receptors which sense the contraction of active stretch of the muscles and sends it to the brain. The brain sends the response and the muscle act by the inverse myotatic reflex.

Thus, Option-A is the correct answer.
