The wave propagates outward horizontally across the surface of the pond. As you can see from the ripples, the water molecules move up and down, <em>perpendicular to the horizontal movement of the wavefronts</em>.

By definition this is a transverse wave.

A suspicious-looking man runs as fast as he can along a moving sidewalk from one end to the other, taking 2.10 s. Then security

N76 [4]

Answer:1.37

Explanation:

Given

Man run along the side walk and take 2.1 s

While walking in the opposite direction it takes 13.2 s

Let the speed of man and sidewalk be $v & v_s$

Let the distance between two points be x

$x=(v+v_s)2.1 ------1$

$x=(v-v_s)13.2-----2$

From 1 & 2 we can get

$2.1v+2.1v_s=13.2v-13.2v_s$

$15.3v_s=11.1v$

$\frac{v}{v_s}=\frac{15.3}{11.1}=1.37$

Find the position vector of a particle that has the given acceleration and the specified initial velocity and position. a(t) = 1

kondor19780726 [428]

Answer:

Explanation:

Given

Acceleration $a(t)=14t\hat{i]+\sin (t)\hat{j}+\cos (2t)\hat{k}$ [/tex]

and $v(0)=\hat{i}$

$r(0)=\hat{j}$

we know $a=\frac{\mathrm{d} v}{\mathrm{d} t}$

$\int dv=\int adt$

$v(t)=\int (14t\hat{i}+\sin (t)\hat{j}+\cos (2t)\hat{k})dt$

$v(t)=7t^2\hat{i}-\cos t\hat{j}+\frac{\sin (2t)\hat{k}}{2}+c$

at $t=0$

$v(0)=0-1\cdot \hat{j}+0+c$

$c=\hat{i}+\hat{j}$

$v(t)=(7t^2+1)\hat{i}+(1-\cos t)\hat{j}+\frac{\sin (2t)\hat{k}}{2}$

and $\frac{\mathrm{d} r}{\mathrm{d} t}=v(t)$

$\int dr=\int vdt$

$r(t)=\int ((7t^2+1)\hat{i}+(1-\cos t)\hat{j}+\frac{\sin (2t)\hat{k}}{2})dt$

$r(t)=(\frac{7}{2}t^3+t)\hat{i}+(t-\sin (t))\hat{j}+\frac{1}{2}\times (-\frac{1}{2}\cos 2t)\hat{k}+c_2$

at $t=0$

$r(0)=\hat{j}$

$r(t)=(\frac{7}{3}t^3+t)\hat{i}+(1+t-\sin t)\hat{j}+\frac{1}{4}(1-\cos 2t)\hat{k}$
