The first three would be needed. They take care of the fourth 1 (D). The input and output force and the efficiency are the standard ways of calculating Mechanical advantage for   simple machines. The height and length of the inclined plane is taken into account by the input and output forces and the efficiency.

D is the answer.

If a biker starts at rest and accelerates to 15 m/s in 7.5 seconds, what is his<br> acceleration? *
sergeinik [125]

Answer:

2 m/s^2

Explanation:

from the question

v=15 m/s

t=7.5

a=?

from the first equation of motion

v=u+at

where,

v=final velocity

u=initial velocity

a=acceleration

t=time

from the question (u) will be zero because the body started at rest

v=u+at

15=(0)+a×7.5

15=7.5a

a=15/7.5

a=2 m/s^2

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.
