What are the differences between a magnetic and gravitational interaction

Physics
1 answer:
GREYUIT [131]3 years ago
3 0
Classically, gravitational attraction is due to the masses of objects. It is inversely proportional to the square of the distances between the objects.

Magnetic attraction is due to the magnetism in objects which is due to uncompensated electron spins in certain atoms.  The force due to magnetism less easy to put into one equation than gravity since magnetic fields can have different shapes, but the simplest one (the dipolar field) is inversely proportional to the cube of the distance between the magnetic dipoles.

Which of the following states that absolute zero cannot be reached?
olganol [36]
The second and third laws of thermodynamics states that absolute zero cannot be reached. The correct option among all the options that are given in the question is the third option or option "C". Both the laws actually deal with the relations that exist between heat and other forms of energy. I hope the answer helps you.

Why does the shape of the lens in your eye change?
Nina [5.8K]

The Lens Changes Shape to Focus Near Objects. Light rays from objects that are close to the eye are not parallel. Therefore, the eye must bend them more in order to focus the rays on the retina. To accomplish this, the lens change shape.

In a certain experiment, a radio transmitter emits sinusoidal electromagnetic waves of fre- quency 110.0 MHz in opposite directi
Shkiper50 [21]

To solve the problem it is necessary to take into account the concepts related to frequency depending on the wavelength and the speed of light.

By definition we know that the frequency is equivalent to,

f=\frac{c}{\lambda}

where,

c= Speed of light

\lambda = Wavelength

While the wavelength is equal to,

\lambda = \frac{2L}{n}

Where,

L = Length

n = Number of antinodes/nodes

PART A) For the first part we have that our wavelength is 110MHz, therefore

\lambda = \frac{c}{f}

\lambda = \frac{3*10^8}{11*10^6}

\lambda = 1.36m

Therefore the distance between the nodal planes is 1.36m

PART B) For this part we need to find the Length through the number of nodes (8) and the wavelength, that is,

\lambda'=\frac{2L}{n}

L = \frac{\lambda n}{2}

L = \frac{8*2.72}{2}

L = 10.90m

Therefore the length of the cavity is 10.90m
