Answer:

A red light, green light, and blue light differ in wavelength

Explanation:

A red light, green light, and blue light differ in wavelength .

Different colors have different wavelengths or frequencies . Two light having different color may have different amplitude . Amplitude decides the intensity of light , not color. Sometimes , a light may be mixture of many color light like white light of the sun . Such light are not pure .

To reduce inductive reactance, what devices are normally placed on transmission or distribution lines?
UkoKoshka [18]

Answer : Capacitors

Explanation : Capacitors are normally  placed on transmission or distribution lines when to reduce inductive reactance.

This is because it enhances electromechanical and voltage stability , limit voltage dips at network nodes and reduces the power loss.

So, we can say that inductive reactance normally replace by the capacitors.

an NHL hockey player (m=90 kg) stands motionless on the ice . the 10 kg stanley cup is thrown to the player at 4m/s. after he ca
spayn [35]

Answer:v=0.4 m/s

Explanation:

Mass hockey player m_1=90 kg

mass of  cup m_2=10 kg

Velocity of cup u=4 m/s

let v be the velocity of the combined system

Conserving momentum

m_1\cdot 0+m_2u=(m_1+m_2)v

v=\frac{10\times 4}{100}

v=\frac{40}{100}

v=0.4 m/s

Answer: Bohr's model (1913)

  Niels Bohr improved Rutherford's model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. The Dalton model has changed over time because of the discovery of subatomic particles.

Bohr's model (1913)

  Niels Bohr improved Rutherford's model. Using mathematical ideas, he showed that electrons occupy shells or energy levels around the nucleus. The Dalton model has changed over time because of the discovery of subatomic particles

  Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.

  John Dalton

The idea that everything is made of atoms was pioneered by John Dalton (1766-1844) in a book he published in 1808. He is sometimes called the "father" of atomic theory, but judging from this photo on the right "grandfather" might be a better term.
