If your vehicle sinks in water, which window should you kick out when the pressure equalizes?

iragen [17]

<span>If your vehicle sinks in water and assuming that you are the driver, you should kick out the driver's window when the pressure equalizes.

You should't waste your time trying to reach the rear window and you shouldn't break the front window. Therefore, just break the one nearest to you which is the driver's window in this case.</span>

When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a sp

Zielflug [23.3K]

Answer: $d=7.94\times 10^5\ m$

Explanation:

Given

Speed of Primary wave $v_1=8\ km/s$

Speed of secondary wave $v_2=4.5\ km/s$

difference in timing of two waves are $77.2\ s$

Suppose both travel a distance of d km then

$t_1=\frac{d}{8}\quad \ldots (i)$

$t_2=\frac{d}{4.5}\quad \ldots (ii)$

Subtract (ii) from (i)

$\frac{d}{4.5}-\frac{d}{8}=77.2$

$d[\frac{1}{4.5}-\frac{1}{8}]=77.2$

$d[0.0972]=77.2$

$d=794.23\ km$

$d=7.94\times 10^5\ m$

The distance traveled by an object can be modeled by the equation d = ut + 0.5at2 where d = distance, u = initial velocity, t =

Taya2010 [7]

We are given with the expression d = ut + 0.5 at^2 and is asked to express the equation in terms of a. First, we transpose ut to the left side, then we multiply to the equation and divide lastly the resulting equation by t^2. The final expression becomes a = 2(d-ut)/t^2.
