How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor, and insulator in answer.

Answers

Answer 1

Answer: The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.

Answer 2

Answer:

Answer:

Battery is the source of electrical energy which will help the charge to flow through a medium.

Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.

When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.

It is given as

$q\Delta V = (1)/(2)mv^2$

so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.

A species of insect is newly introduced into the United States from the Philippines. This insect becomes established, laying its eggs on the leaves of oak trees. How can a biologist determine if the relationship between the insect and the oak tree is commensalism, mutualism, or parasitism?

Answers

Commensalism describes the interaction between the insect and the oak tree.

What is commensalism?

It is a type of biological interaction between two species in which one of the interacting species is benefitted while the other species is unaffected.

How is the above interaction commensalism?

Since the insect gets a safe place to lay its egg it gains from this interaction while the tree is unaffected.

When will this interaction be a mutualism interaction?

When both the organisms benefit from the interaction.
If the insect helps in the pollination of the tree while the insect gets a safe place to lay its egg.

When will this interaction be a parasitic interaction?

When one of the organism benefit at the expense of the other.
For example, If the insect sucks the sap of the tree on which it lays its egg. The insect benefits while the tree is harmed.

Is it possible to have 400m distance and yet zero for displacement? Please explain by using an example.

Answers

Yes, If you travel in a circle that has a circumference of 400 m and you complete that four hundred metres you will end up in the same spot. Imagine a 400 m race track. You complete 1 lap you end up where you started, hence no displacement, but you have traveled 400 m

Charge Q = +4.00 mC is distributed uniformly over the volume of an insulating sphere that has radius R = 5.00 cm. What is the potential difference between the center of the sphere and the surface of the sphere?

Answers

The potential difference between the center of the sphere and the surface of the sphere will be PD=3.6 x 10^8 V

What will be the potential difference?

It is given that:-

Charge Q = +4.00 mC or $4*10^(-3) c$

insulating sphereradius R = 5.00 cm = 0.05 m

The formula for the potentialdifference at the surface of the sphere is given by

$V_(s) =(K* Q)/(r) =(9*10^(9) * 4*10^(-3) )/(0.05)=7.2*10^(8) V$

The formula for the potentialdifference at the center of the sphere

$Vc_{} =(3)/(2) * V_(s)$

$V_(c) = 1.5*7.2*10^(8) v = 10.8*10^(8 ) V$

The difference between the potential difference will be

$V=V_(c) -V_(s) = 10.8*10^(8) =3.6*10^(8) V$

Thus the potential difference between the center of the sphere and the surface of the sphere will be PD=3.6 x 10^8 V

Answer:

3.6 x 10^8 V

Explanation:

Q = 4 m C = 4 x 10^-3 C

r = 5 cm = 0.05 m

The formula for the potential at the surface is

Vs = K Q / r = (9 x 10^9 x 4 x 10^-3) / 0.05 = 7.2 x 10^8 V

The formula for the potential at the centre is

Vc = 3/2 Vs

Vc = 1.5 x 7.2 x 10^8 V = 10.8 x 10^8 V

The difference in potential is

V = Vc - Vs = 10.8 x 10^8 - 7.2 x 10^8 = 3.6 x 10^8 V

Epsilon Eridani is a star that is 10.5 light years away from Earth. One light year is about 9.46 trillion kilometers The distance between the star and Earth in kilometers is trillion kilometers?

Answers

Given the relation that 1 light year = 9.46 trillion kilometers, and the distance from Epsilon Eridani to Earth which is 10.5 light years, we can solve for the distance between the star and Earth in light years by multiplying both values together. This is shown below

Dsitance (in trillion km) = 9.46 trillion km * (10.5) = 99.33 trillion kilometers

Answer:99.33

Answers

By looking at the equation
C12H22O11 + 11H2SO4 12C + 11H2SO4 + 11H2O
we can conclude that the concentrated sulfuric acid is a catalyst because
the sulfuric acid doesn't react with the reactant and it is not consumed.
