Which theory proposes that the moon was a passing asteroid pulled into orbit by Earth's gravity?

Answers

The correct answer to the question above is the capture theory. The capture theory proposes that the moon was a passing asteroid pulled into the orbit by the Earth's gravity. It says that the moon was originally orbiting the sun, not the Earth.

Answer:

Capture Theory

Explanation:

According to capture theory, moon is passing space rock-asteroid which was captured into the orbit around the Earth due to gravity. Other planets have moons which are captured asteroid like Mars has two moons-Phobos and Deimos. Jupiter has many moons which are captured asteroids. Capture theory explains the difference in the composition of Earth and the moon.

A bicycle and rider travel along a road. Which is true?A. The bicycle and the rider undergo translation.
B. Only the rider undergoes a translation.
C. Only the bicycle undergoes translation.
D. Neither the bicycle nor the rider undergoes a translation.

Answers

Answer:

A. The bicycle and the rider undergo translation.

Explanation:

When a rider is riding his bicycle along the road, the wheels of the bicycle will rotate. This rotation of wheels translates both the rider and the bicycle in space.

So the correct answer is option A
A bicycle and rideer travel along a road. the true about the sentence is: a. the bicycle and the rider undergo translation. The rider moving because you have to push the pedals and make the bike moves too.

hope this help

Activation Energy is the amount of energy needed to get a reaction started.

_____________ is an excessive current relative to normal operating current, but one that is confined to the normal conductive path provided by the conductors, circuit components, and loads of the distribution system. A(n) _________ is a current that flows outside the normal conducting path. One generally accepted definition of _______is when a phase or ungrounded conductor comes in contact with, or arcing current flows between, another phase conductor, neutral, or ground.

Answers

Answer:

Overload current, short-circuit current and short circuit

Explanation:

Overload current is an excessive current relative to normal operating current, but one that is confined to the normal conductive path provided by the conductors, circuit components, and loads of the distribution system.

A short-circuit current is a current that flows outside the normal conducting path.

One generally accepted definition of short circuit is when a phase or ungrounded conductor comes in contact with, or arcing current flows between, another phase conductor, neutral, or ground.

What does the wavelength of visible light waves correspond to?

Answers

The wavelength of the visible range of the electromagnetic spectrum lies between \boxed{400\,{\text{nm}} - 700\,{\text{nm}}} .

Further Explanation:

The Electromagnetic spectrum is the complete range of the electromagnetic radiation which expresses all the radiation starting from the Gamma rays to the radio waves. The electromagnetic spectrum is the detailed spectrum that explains all the electromagnetic radiations.

The electromagnetic radiations are the transverse waves which do not require any medium for their propagation. The electromagnetic waves can easily travel through space. All the electromagnetic radiations travel at the speed of light.

The different radiations in the electromagnetic spectrum are as follows:

  • Gamma rays
  • X-rays
  • Ultraviolet rays
  • Infrared rays
  • Micro waves
  • Radio waves

The wavelength and the frequency ranges for the different electromagnetic radiations is as shown in figure attached.

Therefore, the wavelength of the visible range of the light in the electromagnetic spectrum is \boxed{400\,{\text{nm}} - 700\,{\text{nm}}} .

Chapter: Electromagnetic Waves

Keywords:

Electromagnetic spectrum, visible light, EM waves, wavelength, 700nm, 400 nm, 7000 A, frequency, gamma rays, transverse waves.

Explanation:

Visible light is a very part of electromagnetic spectrum. We can see the visible region of the electromagnetic spectrum.

The frequency and the wavelength has an inverse relationship.

For example, the red light has large wavelength and low frequency. Violet has a short wavelength and higher frequency.

The frequency range of visible region is from 400 nm to 700 nm.
