Answer: a. Electric current produces magnetic field

Explanation: Ørsted discovered that the passage of steady electric current through a wire creates a magnetic field around it.

His discovery marked the first connection between electricity and magnetism.

Answer:

A. Electric currents produce magnetic fields.

Explanation:

Answer:

A. Electric currents produce magnetic fields.

Explanation:

Hans Christian Ørsted discovered that electric currents had a property of producing magnetic fields. This finding was the first established relationship found between electricity and magnetism.

He noticed that a compass deflected when current was switched on and off and this marked the first established relationship between electricity and magnetism.

Four oranges were placed in a series circuit. Approximately what voltage did this produce?
vampirchik [111]

Answer:

Four times the original amount if only one orange was used

Explanation:

We can assume that the oranges all have equal voltages. Connecting them in series will have an increasing effect on the voltage delivered. In our case, this will produce 4 times the voltage of the circuit when only one orange is used.

Whenever simple cells are connected in series, the voltages of the individual cells are added up to form the voltage of the whole circuit.

Let us assume that the voltage of each of the oranges is approximately 0.9 volts. The Voltage produced when the 4 oranges are joined in series is 0.9 + 0.9 + 0.9 + 0.9 = 3.6 volts

Identify the major force between molecules of pentane. dispersion dipole-dipole hydrogen bonding ion-dipole ion-ion
Lyrx [107]
It wouldn’t be hydrogen bonding because hydrogen bonding takes place with highly electronegative elements like N,O & F being the most electronegative. It’s not ion - dipole because there is no ion present. So I’m sure it is dispersion

Choose a reasonable explanation to account for the differences. There may be more than one possible reason that makes sense, jus
Ugo [173]

Answer:

A. It is possible not all of the water was evaporated from the sand, causing the recovered mass to be higher

D. While drying the NaCl, the liquid boiled and some splattered out of the evaporating dish, causing the recovered mass to be higher.

Explanation:

Sand absorbs water and stores it. The sunlight causes the water to evaporate but sand can hold some of the water inside it. This results in increase in mass of the sand. The mass of sand before and after the water evaporation can be different.

Explain the purpose and function of a gene.
Kryger [21]

Function

Genes decide almost everything about a living being. One or more genes can affect a specific trait. Genes may interact with an individual’s environment too and change what the gene makes.

Genes affect hundreds of internal and external factors, such as whether a person will get a particular color of eyes or what diseases they may develop.

Some diseases, such as sickle-cell anemia and Huntington’s disease, are inherited, and these are also affected by genes.

Purpose

The purpose of genes is to store information.

Each gene contains the information required to build specific proteins needed in an organism.

Hope this helps !!
