Which type of electricity moves along part way to turn on light

A meter stick whose mass is 260 grams lies on ice. You pull at one end of the meter stick, at right angles to the stick, with a

Lelu [443]

Answer:

a = d p / dt = 23 m / s², The direction is the direction of the force

Explanation:

Newton's second law can be written in the form

F = dp / dt

How the body is initially at rest

F = m a

a = F /m

a = 6 /0.260

a = 23 m / s²

a = d p / dt = 23 m / s²

The direction is the direction of the force

Help answer all for prize

marusya05 [52]

Explanation:

Average speed =total distance ÷ total time

speed = d ÷ t

d= 74400

t= 16

then,

speed = 74400÷16

=4650

A woman is sitting at a bus stop when an ambulance with a siren wailing at 317 Hz approaches at 69 miles per hour (mph). Assume

xxMikexx [17]

Answer:

a) 30.84m/s

b) 348.32Hz

c) 32.34m/s

d) 289.69Hz

Explanation:

a) If 1 mile=1609,34m, and 1 hour=3600 seconds, then 69mph=69*1609.34m/3600s=30.84m/s

b) Based on Doppler effect:

/*I will take as positive direction the vector $\vec r_{observer}-\vec r_{emiter}$ */

$f_{observed}=(\frac{v_{sound}-v_{observed}}{v_{sound}-v_{emited}})f_{emited}$

$f_{observed}=(\frac{343m/s-0m/s}{343m/s-30.84m/s})317Hz=348.32Hz$

c) $350Hz=(\frac{343m/s-0m/s}{343m/s-v_{ambulance}})317Hz, V_{ambulance}=343m/s-\frac{317Hz}{350Hz}.343m/s=32.34m/s$

d) $f_{observed}=(\frac{343m/s-0m/s}{343m/s+32.34m/s})317Hz=289.69Hz$

an electromagnetic plane wave travels through some transparent medium and consists of electric and magnetic fields given by

maxonik [38]

Wave length(K) = $1.3*10^{7}$ rad/m

wavelength = $\frac{2n}{k}$

wavelength = $\frac{2π}{1.37*10^7}$

wavelength = 4.584* $10^{-7}$ / $m^{-1}$

wavelength = 4.58* $10^{-7}$ m

What is wavelength?

The distance over which a periodic wave's shape repeats is known as the wavelength in physics. It is a property of both traveling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings. The spatial frequency is the reciprocal of wavelength. The Greek letter lambda () is frequently used to represent wavelength. The term wavelength is also occasionally used to refer to modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.
