What is the average total energy density in electromagnetic radiation that has an intensity of 475 W/m^2?

Physics

Andreas93 [3]3 years ago
5 0

Answer:

1.6 x 10⁻⁶ J/m³

Explanation:

I = Intensity of electromagnetic radiation = 475 Wm⁻²

U = average total energy density of electromagnetic radiation

c = speed of electromagnetic radiation = 3 x 10⁸ m/s

Intensity of electromagnetic radiation is given as

I = Uc

Inserting the values

475 = U (3\times 10^{8})

U = 1.6 x 10⁻⁶ J/m³

An object's buoyant force and weight mean the same thing.<br><br>A. True<br><br>B. False​
german

Answer:

False

Explanation:

No. The buoyant force on an object is the portion of its weight that appears to vanish

when the object is in any fluid (could be either a liquid or a gas).

If the object happens to float in a particular fluid, then the buoyant force at that moment

is equal to the object's weight.

Notice that the buoyant force on an object will be different in different fluids.

How do objects and substances have kinetic energy??<br><br> I need help ASAP!!
9966 [12]

Objects and substances in motion have Kinetic Energy.

Explanation:

Kinetic Energy is the motion of objects, substances, molecules, atoms .

Whenever an object starts to move, it is in motion. Kinetic Energy is generated, when the object moves and its potential energy gets dropped with the movement. Kinetic Energy is found in every object that moves.

The Kinetic Energy of an object depends both on its mass and its speed. Kinetic Energy increases as mass and speed are increased.

Example:  By using the wind flow from wind turbines, the Kinetic energy in the wind can be transformed to generate electricity by using generators.
