In the ballistic pendulum experiment (A.K.A conservation of momentum & energy), the velocity of the projectile was measured

and recorded (vo = 3.94 m/s). The mass of the projectile was 12.1 g and the ballistic pendulum mass was 103.3 g. After the projectile is fired, it hits the ballistic pendulum, and both moved with velocity LaTeX: vv. If the pendulum length is 0.32 m, calculate the maximum angle that the ballistic pendulum (with projectile) reached after the collision.

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.

Any of two or more forms of the same element which differ only in the number of neutrons their atoms contain is called an

C. isotope

Isotopes have the same atomic number but different mass number because of the difference in the number of neutrons in the nucleus of the atom.

Betelgeuse is 100,000 times more luminous than our sun, which means that it releases an estimated 3.846 x 1031 W of luminous lig
denis-greek [22]

Answer:

5.4  × 10⁸ W/m²

Explanation:

Given that:

The Power (P) of Betelgeuse is estimated to release 3.846 × 10³¹ W

the mass of the exoplanet = 5.972 × 10²⁴ kg

radius of the earth = 1.27 × 10⁷ m

half the distance (i.e radius r ) = 7.5  × 10¹⁰ m

a) What is the intensity of Betelgeuse at the "earth’s" surface?

The Intensity of  Betelgeuse  can be determined by using the formula:

Intensity \ I = \frac{P}{4 \pi r^2}

I = \frac{3.846*10^{31}}{4 \pi (7.5*10^{10})^2}

I = 544097698.8 W/m²

I = 5.4  × 10⁸ W/m²

Which best summarizes a concept related to the work-energy theorem?
rusak2 [61]
The concept of work-energy theorem has become much of a fundamental principle in the field of physics, mechanics, and engineering. In addition, this theory primarily states that the change of kinetic energy of the system is equal to the sum of the work done that is acted by all forces on the object.
