can the suns gravitational pull on the earth affect the temperature as the gravitational pull could suck us in like a black hole
Harlamova29_29 [7]
A black hole doesn't suck things in any harder than any other object does, unless you're closer to it. The Earth hasn't gotten any closer to the sun in many years. This is not the reason for climate change.

Which visible colors of light has the highest frequency?
Valentin [98]

Answer:

Violet color has the highest frequency.

Explanation:

Light: it can behave as particle and wave. It has both natures. Frequency is the characteristic of the wave. It is defined as how many waves can pass through at a point in a given interval of time. It is measured in hertz.

Red: It lies in the visible region of the light. it has the lowest frequency in the visible region of the light.

Violet:  It lies in the visible region of the light. Every wave has some energy. The energy of the wave is directly proportional to the frequency of the wave. More the energy of the wave then more will be the frequency of the wave. Violet color has more energy. It has the highest frequency.

What's the dielectric constant of ceramic?<br> A. 1,200<br> B. 900<br> C. 80<br> D. 7.500
I am Lyosha [343]

Answer:

7.5

Explanation:

The dielectric constant of ceramics is about 7.5.

The dielectric constant of a substance is the ratio of the electric permeability of a substance to the electric permeability of free space.

Dielectric constant gives a good overview about the ability of substance to store charges compared to another.

Most substances have their electric constant and they suggest the ease by which they can store electrical energy. This is very important in developing capacitors.
