<span>In order to make 4 complete revolutions in 4 seconds, the wheel must have a constant angular acceleration of 144° (or 2.5 radians) per square second, hence after 8 seconds the wheel will have made 14,4 revolutions, or 5184° in total.</span>
The mountains can and will block airflow from higher pressure systems that come in from a coast and won't combine to nake storms
a) It can dissolve other substances and has high specific heat capacity.
b) Pressure is transferred equally in all directions
c) F=14*0.04/0.02=28 N
d) I'd expect that it will sink cause weight will pull it to the bottom
e) Because the buoyant force is stipulated by difference between pressures in the top and bottom surfaces of a body.
f) Because this force increases in denser liquids:
, where rho is density.
g) Q=Av, where v - speed, A - area. With the same flow rate v=Q/A, so larger area decreases speed and vice versa.
A black sweater. Why? Because black is the most absorbent color while as white is reflecting the light. Hope this helps...
