A jet play sits on the runway and then rapidly accelerates does it go to potential to kinetic energy?

A main difference between asteroids and comets is that asteroids are mostly made of rock and comets are mostly made of metals ca

avanturin [10]

We can confirm that the difference between a comet and an asteroid lies in their compositions and physical characteristics derived from those compositions.

As stated in the question, the main difference between an asteroid and a comet is their compositions, meaning the materials from which they form.

Asteroids are rocky objects which a heavy metal composition, while comets tend to be made of dust, ice, and some rocky material. Some extra differences include:

Comets reflect a steady amount of light (because of their ice composition)
Asteroids will reflect light at random intervals due to some metals that may be present on their surface
Comets tend to have a tail made of water from the melting ice when reflecting sunlight.

Therefore, we can confirm that the main difference between asteroids and comets is their compositions, which lead to distinct physical characteristics.

What is the function of eye lens of human eye

Arte-miy333 [17]

Answer:

the lens is located in the eye. by changing its shape, the lens changes the focal distance of the eye. in other words,it focuses the light rays that pass through it (and onto the retina) in order to create clear images of objects that are positioned

at various distances.

mafiozo [28]

Answer: Option D: It has a high amount of inertia is correct.

Explanation: Inertia is the reason heavy things don't like to move very easily. Heavy objects have a high amount of inertia making them harder to move while lighter things have a lower a mount of inertia making them easier to move.

A uniform electric field of magnitude 442 N/C pointing in the positive x-direction acts on an electron, which is initially at re

Brums [2.3K]

A) The electric field is constant and in the same direction as the electron's displacement, so the work done is given by:

W = Fd

W = work, F = electric force, d = displacement

The electric force on the electron is given by:

F = Eq

F = electric force, q = electron charge

Substitute F:

W = Eqd

Given values:

E = 442N/C, q = 1.6×10⁻¹⁹C, d = 3.50×10⁻²m

Plug in and solve for W:

W = 442(1.6×10⁻¹⁹)(3.50×10⁻²)

W = 2.48×10⁻¹⁸J

B) The electric field does work to move the electron. Apply the conservation of energy and you'll see that the electron's potential energy loss is equal to the work done by the field in moving the electron.

The electric potential energy change is -2.48×10⁻¹⁸J

C) Apply the work-energy theorem; the electron's kinetic energy equals the work done on it by the field.

KE = 0.5mv² = W

m = electron mass, v = velocity, W = work

Given values:

W = 2.48×10⁻¹⁸J, m = 9.11×10⁻³¹

Plug in and solve for v:

0.5(9.11×10⁻³¹)v² = 2.48×10⁻¹⁸

v = 2.33×10⁶m/s
