Conduction involves the transfer of electric charge or (thermal energy)

Tema [17]4 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.

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.

What term describes how far an object moves in a certain amount of time

stepan [7]

Answer:

1. Speed

Explanation:

"how far an object moves in a certain amount of time"

"how far an object moves"- distance

"In a " - over

"certain amount of time" - time

Distance over time is speed.

The speed of an object is the distance the object travels in one unit of time.

Hope I Helped, Feel free to ask any questions to clarify :)

Have great day!

A 45.5-turn circular coil of radius 4.85 cm can be oriented in any direction in a uniform magnetic field having a magnitude of 0

il63 [147K]

Answer:

4.399 Nm

Explanation:

The maximum Torque on a coil is given as,

τ = BNIA...................... Equation 1

Where τ = Maximum torque exerted on the coil, B = Magnetic Field, N = Number of turns, I = Current, A = Area.

Given: N = 45.5 Turns, B = 0.49 T, I = 26.7 mA = 0.0267 A,

A = πr², Where r = radius of the coil, r= 4.85 cm = 0.0485 m

A = 3.14(0.0485)²

A = 7.39×10⁻³ m².

Substitute into equation 1

τ = 45.5×0.49×26.7×7.39×10⁻³

τ = 4.399 Nm

Answer:

Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.

a tungsten and coil has a resistance of 12 ohm at 15 degree celsius is the temperature coefficient of resistance of tungsten is

Dennis_Churaev [7]

Answer:

The resistance of the tungsten coil at 80 degrees Celsius is 15.12 ohm

Explanation:

The given parameters are;

The resistance of the tungsten coil at 15 degrees Celsius = 12 ohm

The temperature coefficient of resistance of tungsten = 0.004/°C

The resistance of the tungsten coil at 80 degrees Celsius is found using the following relation;

R₂ = R₁·[1 + α·(t₂ - t₁)]

Where;

R₁ = The resistance at the initial temperature = 12 ohm

R₂ = The resistance of tungsten at the final temperature

t₁ = The initial temperature = 15 degrees Celsius

t₂ = The final temperature = 80 degrees Celsius

α = temperature coefficient of resistance of tungsten = 0.004/°C

Therefore, we have;

R₂ = 12×[1 + 0.004×(80 - 15)] = 15.12 ohm

The resistance of the tungsten coil at 80 degrees Celsius = 15.12 ohm.
