The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure (in atm) du

frozen [14]

Answer:

$P = 103867260$ atm

Explanation:

The pressure at the bottom of any liquid column is equal to product of density of the liquid , gravitational acceleration constant (g) and height of the water column

Thus, $P = \rho*g*h$

Substituting the given values, we get -

$P = 1029$ kg/m3 $* 9.8$ m/s^2 $*10.3 *1000$ meters

$P = 103867260$ atm

Two coherent sources of radio waves, A and B, are 5.00 metersapart. Each source emits waves with wavelength 6.00 meters.Consider

alexgriva [62]

Answer

given,

distance between A and B is equal to 5 m

let x be the distance of loud speaker from the source A

For constructive interference, path difference = mλ

x - (5 - x ) = 0 , for m = 0

2 x - 5 = 0

2 x = 5

x = 2.5 cm

For destructive interference

$|x - (5 - x )| = (2 m + 1)\dfrac{\lambda}{2}$

m = 0

$|2x - 5| = \dfrac{\lambda}{2}$

$|2x - 5| = \dfrac{6}{2}$

$\pm(2x - 5) = 3$

x = 4 , 1 cm

Does the speedometer of a car read average speed or instantaneous speed?

aleksandrvk [35]

Speedometer of car read instantaneous speed of course. Its because when you stop it instantaneous show 0. If speedometer show average speed there should be different value than 0 (much greater) just when you stop.
Maybe there are car with speedometer with average speed but the time from which the average is taken is extremely small. Its simply instantaneous speed.
