If it takes a P wave five minutes to travel from the epicenter to a seismic station, approximately how long will it take an S wa

jok3333 [9.3K]

It take approximately 9 minutes for an S wave to travel that same distance that P wave travel in 5 minutes.

P waves, are the first waves to arrive at a seismograph.

An S wave, or shear wave, is a seismic body wave that shakes the ground back and forth perpendicular to the direction the wave is moving.

S-wave is about 1.73 times slower than the P-wave.

An ore car of mass 35000 kg starts from rest and rolls downhill on tracks from a mine. At the end of the tracks, 17 m lower vert

BaLLatris [955]

Answer:

Explanation:

Given

mass of car $m=35,000 kg$

Vertical displacement $h=17 m$

spring constant $k=5.3\times 10^5 N/m$

Considering we need to find out compression in the spring when it reaches to ground

Here Gravitational potential Energy is converted to kinetic energy which finally converts to Elastic Potential Energy

suppose x is the compression in spring

Potential Energy=mgh

Elastic potential energy $=\frac{1}{2}kx^2$

$35000\times 10\times 17=0.5\times 5.3\times 10^5\times x^2$

$x=4.73 m$

HELP ASAP!! WILL TRY TO GIVE BRAINLIESTT!!

svet-max [94.6K]

Answer:

If a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

hope this helps!!!

A plane electromagnetic wave travels northward. At one instant, its electric field has a magnitude of 3.7 V/m and points eastwar

UNO [17]

Answer:

Magnetic field, B = $1.24\times 10^{-8}\ T$ (eastwards)

Explanation:

Given that,

The magnitude of electric field, E = 3.7 V/m

A plane electromagnetic wave travels northward. We need to find the magnitude and direction of the magnetic field at this instant.

The relation between the magnetic field and the electric field of the plane electromagnetic wave is given by :

$B=\dfrac{E}{c}$

c is the speed of light

$B=\dfrac{3.7}{3\times10^8}\\\\B=1.24\times 10^{-8}\ T$

So, the magnetic field is $1.24\times 10^{-8}\ T$ . The direction of magnetic field is perpendicular to the electric field and the direction of wave propagation. Hence, the direction of magnetic field is eastward.
