If we start taking into account the free body diagram, we then start damping motion of a body by means of this equation:
<span>m * d^2 x/dt^2 + c* dx/dt + k* x = 0 </span>
<span>free undamped motion is when (c =0) </span>
<span>therefore </span>
<span>50* d^2 x/dt^2 + 200* x = 0 </span>
<span>w = omega = sqrt(k/m) = sqrt(200/50) = 2 </span>
<span>Then </span>
<span>A*cos(w*t) + B*sin(w*t) = x </span>
<span>find A and B using intial conditions and you will get the rest that you need. Hope this helps</span>
During convection of air currents, cool air sinks. <em>(b)</em>
A neutron is a particle that it doesn´t carries charge, a neutron is a neutral particle.
An electron is a particle that carries a negative charge, and a proton is a particle that carries a positive charge.
b.False.
Good luck.
Continental lithosphere is thicker and less dense than oceanic
lithosphere. Continental crust is primarily composed of
granitic rock while oceanic crust is composed
<span>primarily of basaltic rock.</span>
