Conduction involves the transfer of electric charge or (thermal energy)
Tema [17]3 years ago
3 0

Answer: The correct answer is "thermal energy".

Explanation:

Conduction: Heat flows from hotter body to colder body provided they are placed in direct contact with each other until the temperatures on both bodies become equal.  In conduction, there is not actual movement of matter.

Thermal energy: It is the energy that comes from the heat.

or

Conduction is the process in which there is a transfer of the electrons between the charged object to the another object provided the objects are in direct contact with each other. The electrons are transferred from the object having more negative charge to the object that has more positive charge. There is a transfer of the electrons until the charges on both the objects become equal.

Therefore, the conduction involves the transfer of the electric charge or thermal energy.

Find the frequency of a wave with a period of 0.5 seconds
strojnjashka [21]

Frequency of the wave is 2 per second

Explanation:

  • Frequency is the number of times waves pass at a particular point of time. Here, time period = 0.5 s
  • Frequency is given by the formula

f = 1/T, where f is the frequency and T is the time period

⇒ f = 1/0.5 = 2 per second

An aluminum "12 gauge" wire has a diameter d of 0.205 centimeters. The resistivity ρ of aluminum is 2.75×10−8 ohm-meters. The el
Alborosie

Answer:

I = 4.75 A

Explanation:

To find the current in the wire you use the following relation:

J=\frac{E}{\rho}      (1)

E: electric field E(t)=0.0004t2−0.0001t+0.0004

ρ: resistivity of the material = 2.75×10−8 ohm-meters

J: current density

The current density is also given by:

J=\frac{I}{A}        (2)

I: current

A: cross area of the wire = π(d/2)^2

d: diameter of the wire = 0.205 cm = 0.00205 m

You replace the equation (2) into the equation (1), and you solve for the current I:

\frac{I}{A}=\frac{E(t)}{\rho}\\\\I(t)=\frac{AE(t)}{\rho}

Next, you replace for all variables:

I(t)=\frac{\pi (d/2)^2E(t)}{\rho}\\\\I(t)=\frac{\pi(0.00205m/2)^2(0.0004t^2-0.0001t+0.0004)}{2.75*10^{-8}\Omega.m}\\\\I(t)=4.75A

hence, the current in the wire is 4.75A
