A scientist is studying a shock wave from an earthquake. What kind of wave is being studying?
Pavel [41]

Answer:

Longitudinal Mechanical Wave

Explanation:

Mechanical waves are the waves that require medium to propagate. And a longitudinal wave is a wave in which the vibration of the energy(here: mass specifically) is in the direction of propagation of wave.

Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.

Shock waves travel faster than sound and their speed increases as the amplitude of the wave is increased but their intensity fades faster due to the fact that some of its energy gets expended in the form of heat due to the resistance of the medium.

Peak wavelength of light coming from a star with a temp of 4300k
PSYCHO15rus [73]

from Wein's law

\frac{k}{ \lambda_{max} }  = T \\ \lambda_{max} =  \frac{k}{T}  \\ \lambda_{max} =  \frac{3.898 \times  {10}^{ - 3} }{4300}   \\  = 9.065 \times  {10}^{ - 7}

BigorU [14]

Answer:

  8.067 ohms

Explanation:

The relationship between voltage, resistance, and power is ...

  P = V²/R

so ...

  R = V²/P = 110²/1500 = 8 1/15

  R ≈ 8.067 . . . ohms
