The peak magnetic field strength in a residential microwave oven is 9. 2 x 10-5 t. what is the intensity of the microwave?
Alexandra [31]

The intensity of the microwave is 10.09 × 10⁵ W/m².

The unit of magnetic induction is the tesla (T). The magnetizing force, which induces the lines of force through a material, is called the field intensity, H (or H-field), and by convention has the units ampere per meter (A m−1) .

The portion of a material's magnetic field that results from an external current and is not intrinsic to the material itself is known as the magnetic field strength, also known as magnetic intensity or magnetic field intensity. It is measured in amperes per meter and represented as the vector H.

Magnetic Field, B = 9.2 × 10⁻⁵ T

I_{avg} = \frac{CB_0^2}{2\mu _0}

       = \frac{(2.998*10^8 m/s) (9.2 * 10^-^5 T)^2}{2 ( 4\pi  * 10^-^7)}

      = 10.09 × 10^5 \frac{W}{m^2}

Therefore, the intensity of the microwave is 10.09 × 10⁵ W/m².

How is a front defined in terms of weather ?. A) the leading edge of an anticyclone flow. B) the trailing edge of a warm front.
Svetllana [295]
A front is defined as a "boundary" that separates two masses of different air densities. I am not entirely sure, but I think the answers are either C or D, but I'm mostly convinced it's option D.

A person weighs 167 lb. The acceleration of gravity is 9.8 m/s 2 . Determine her weight in newtons and her mass in kilograms
sergejj [24]

Explanation:

Weight (N) = Mass * Acceleration

75.74 kg = Mass * 9.8 m/sec^2

Mass = 7.72 kg

Weight = 75.74 N

A paint brush is dropped from the top of a tall ladder and free falls to the ground. What changes, if any, would be observed of
muminat

Answer:

Explanation:

As the paint brush is dropped from the top of a tall ladder it started free falling

i.e. velocity of brush increases as it falls down due to the acceleration provided by gravity.

We know acceleration due to gravity is the attraction experienced by the object due to earth attraction

Value of acceleration due to gravity is constant i.e. 9.8\ m/s^2

Therefore the correct choice is

velocity is increasing and acceleration is constant
