Two students suggest different functions for the battery plays a flashlight.

Physics

KiRa [710]3 years ago

Answer:

Student B is correct

Explanation:

The battery acts like a pump to drive the electric charge. The electric charge comes from the conducting material but the battery provides a potential difference or a gradient of flow for this charge which is necessary for the movement of the charge along the conductor.

Answer:

Student b

Explanation:

Because, Battery pumps the charges around the circuit. Here, charges are the free electrons. And this charges are already present in the conductor. When we connect this conductor with the battery - It set up an electric field and The diffrence between the potential between the ends of the wire pushes this free charges to move in perticular direction. (This is called electric energy)

This electric energy is converted by chemical reactions in the battery. When the battery is dead - It means that the chemical energy producing chemicals has been consumed. thereafter there will be no more chemical reactions takes place to produce electric energy. Hence we say that the battery is dead.

For a transverse wave, what is a wavefront?
vichka [17]

Explanation:

A wavefront is the long edge that moves, for example, the crest or the trough. Each point on the wavefront emits a semicircular wave that moves at the propagation speed v. These are drawn at a time t later, so that they have moved a distance s = vt.

What does stressing an Equilibrium system mean? How is stress Applied?
horsena [70]
Stressing an equilibrium simply means that the physical properties in which already exists are balanced. Stress can be applied by either changing the pressure or the volume or temperature.

Where were most of the elements "forged" on the periodic table ​
klemol [59]
<h2>Answer: Stars</h2>

Most of the chemical elements of the Periodic Table were formed or "<em>forged</em>" in the different types of stars that exists in the universe in their different phases of life.

For example, a young star is composed mainly of Hydrogen, the simplest chemical substance and <u>the first in the Periodic Table</u>; being this the element that leads to the other known elements. Taking into account that the two components of each hydrogen atom (1 proton and 1 electron) are separated, the great pressure within the star manages to merge (fuse) two protons.

What does this mean?

Well, sometimes a proton captures an electron and becomes a neutron, but when two protons and two neutrons join together, they form the Helium nucleus, which is <u>the second element in the periodic table</u>. Then, when two helium nuclei join and form the nucleus of another element, Beryllium and so on.

So, by means of the nuclear fusion process the nuclei of most of the  elements lighter than Iron (which is the chemical element 26 of the periodic table) can be formed.

Now, elements that are heavier than Iron can be forged within the stars through the capture of neutrons. In this way, the collapse of the star's center core occurs so quickly that it generates huge shock waves that eject the outer layers of the star into space becoming a <u>supernova</u>. Then, it is during the few seconds of collapse that the specific pressure and temperature conditions in the supernova are created and allow heavier elements to be generated and expelled as interstellar dust and gas.

In this sense, with the explosion of more<u> massive stars</u> and <u>white dwarfs</u> other chemical elements are formed, as well as others that are formed by <u>dying stars of low mass</u> and <u>neutron stars</u>.

However, it should be noted that there are also chemical elements that are artificially formed in experimental fusion nuclear reactors.

an object is accelerated from a constant rate of 5.00 m/s squared what will be its speed after 8.00 seconds
Brrunno [24]

Answer: The answer to this question is velocity =40m/s

Explanation: The acceleration is the change in velocity per unit time.Thus the formula for velocity is v= at

v= 5×8

v= 40m/s

The forces acting on a child sitting in a seat are described by the free-body diagram shown.
melisa1 [442]

Answer:

B.0 N

Explanation:

Based on the description of the free-body diagram, there are only two forces acting on the child sitting on the seat:

- The force of gravity, Fg=-100 N, in the downward direction

- The normal reaction of the chair on the child, Fn=100 N, in the upward direction

The two forces have same magnitude but in opposite directions, so the net force (resultant of the two forces) is zero:

F_{net}=F_n+F_g=100 N-100 N=0 N
