<span>Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. It is calculated as follows:

Density= 67.2 g / (</span><span>2 cm)^3
Density = 8.4 g/cm^3</span>

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.

A uniform circular disk of moment of inertia 8.0 kg.m² is rotating at 4.0 rad/s. A small lump of mass 1.0 kg is dropped on the d
Mice21 [21]

Answer:

\omega'=32\ rad.s^{-1}

Explanation:

Given:

  • moment of inertial of a uniform circular disk, I=8\ kg.m^2
  • angular speed of rotation, \omega=4\ rad.s^{-1}
  • Mass of lump, m'=1\ kg
  • position of the lump from the center of the disk, r'=1\ m

<u>Using the conservation of the angular momentum:</u>

I.\omega=I'.\omega'

8\times 4=m'.r'^2\times \omega'

32=1\times 1\times\omega'

\omega'=32\ rad.s^{-1}
