Which type of telescope does not require darkness in order to be able to use it?
exis [7]

Answer:

A type of telescope that does not require darkness in order to be able to use it is the refracting telescope

Explanation:

A refracting telescope consists of  a lens and an eyepiece collects light which is then focused to present a magnified, bright and clear  image.

The incident light on a refracting telescope is bent by refraction such that the light is focused to the focal point.

In refracting telescopes, the image is formed by bending light, that is by refraction.

The refracting telescope technology has been applied to binoculars and camera zoom lenses.

What best describes the direction of the electric field on a spherical equipotential surface?
Alla [95]

Answer:

Perpendicular to the surface

Explanation:

- Electric field lines represent the direction of the electric field. The electric field lines also correspond to the direction along which the gradient of the electric potential is maximum.

- Equipotentials are lines or surfaces along which the electric potential is constant: the electric potential does not change moving along an equipotential surface.

Given the two definitions, equipotential lines are always perpendicular to the electric field lines. Therefore, in this problem, the direction of the electric field is perpendicular to the spherical equipotential surface.

What is special relativity
Rudiy27

Answer:

In physics, special relativity (also known as the special theory of relativity) is the generally accepted and experimentally confirmed physical theory regarding the relationship between space and time.

We need special relativity in order to solve for quantum gravity. ... The earth was expanding (thus, it's mass was expanding) through space in all directions in order to create gravity **OOPS** forgot, specifically at an accelerating rate… OR… The space must be pushing toward or down on the earth, from every direction.
