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

The blade on a typical table saw rotates at 3300 revolutions per minute. calculate the linear velocity in miles per hour of one

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;

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

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!!
