A seismograph located 1200 km from an earthquake detects seismic waves 5 minutes after the quake occurs. The seismograph oscilla
shepuryov [24]

To solve this problem we will apply the given relationship between wavelength, speed and frequency as well as the use of kinematic equations of motion description.

The wavelength is directly proportional to the speed and inversely proportional to the frequency, in other words,

\lambda = \frac{v}{f}

Where

v = Velocity

f = Frequency

Speed is not given but if the distance traveled in a certain time, that is

v = \frac{d}{t}

Replacing

v = \frac{1200km}{5min}

v = \frac{240km}{min}(\frac{1min}{60s})(\frac{1000m}{1km})

v = 4000m/s

Substituting this value at our first equation we have

\lambda = \frac{v}{f}

\lambda = \frac{4000}{2}

\lambda = 2000m

Therefore the wavelength of the seismic wave is 2000m

yKpoI14uk [10]
C=d(pi)=43.98in. Tip travels 3300 x C = 145,134in per min. (145,134in/min)(1ft/12in)(1 mile/5280ft)(60min/1 hr) = 137.4mph.

Find the self-inductance of a 1700-turn solenoid 55 cm long and 4.0 cm in diameter. Express your answer with the appropriate uni
Nitella [24]

The self-inductance of the solenoid is 8.25 mH.

The given parameters;

  • <em>number of turns, N = 1700 turn</em>
  • <em>length of the solenoid, l = 55 cm = 0.55 m</em>
  • <em>diameter of solenoid, d = 4 cm</em>
  • <em>radius of the solenoid, r = 2 cm = 0.02 m</em>

<em />

The area of the solenoid is calculated as follows;

A = \pi r^2\\\\A = \pi \times (0.02)^2\\\\A = 0.00125 \ m^2

The self-inductance of the solenoid is calculated as follows;

L = \frac{\mu_o N^2 A }{l} \\\\L = \frac{(4\pi \times 10^{-7}) \times 1700^2 \times 0.00125}{0.55} \\\\L = 0.00825 \ H\\\\L = 8.25\ mH

Thus, the self-inductance of the solenoid is 8.25 mH.

How did einstines and Newton’s theory’s differ in terms of explaining the cause of gravity
qwelly [4]

Answer: in the Newton concluded that objects fall because they are pulled by Earth's gravity. Einstein's interpretation was that these objects do not fall.

Explanation: These objects and Earth just freely move in a curved spacetime and this curvature is induced by mass and energy of these objects. - I HOPE THAT HELPED!!
