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 student leaves a pencil on a desk and the pencil stays in the same spot until another student picks it up. What law od motion
lyudmila [28]
Newton’s first law, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

Or in our case an object at rest will stay at rest until an outside force interferes.

The athlete at point A runs 150m east, then 70m west and then 100m east. Determine the resultant displacement of the athlete rel
polet [3.4K]

Answer:

180m to the east

Explanation:

Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.

  point A runs 150m east,

   70m west

  100m east

                                       150m

                --------------------------------------------------------→

                                                                   70m

                                                         ←---------------------

                                                                   100m

                                                         -----------------------------------→

The displacement of the athlete  = 150 - 80 + 100  = 180m to the east

If a net horizontal force of 175 N is applied to a bike whose mass is 50 kg what acceleration is produced?
Crazy boy [7]

The acceleration of the bike is 3.5 m/s^2

Explanation:

We can solve this problem by using Newton's second law of motion, which states that:

F=ma

where

F is the net force on an object

m is the mass of the object

a is its acceleration

For the bike in this problem, we have

F = 175 N is the net force

m = 50 kg is the mass

And solving for a, we find the acceleration:

a=\frac{F}{m}=\frac{175}{50}=3.5 m/s^2
