no.9 indeed all matters are made out of atoms which is smaller than protons and neutrons
<span>12-50t=70t, t= 0.1h = 6 minutes.</span>
Try This Method(substitute your values)
Centripetal force = Mass X Velocity^2/ Radius
<span>F= mv^2/r </span>
<span>so 80.5 X 40^2/200 </span>
<span>=644N</span>
They point towards a negative charge.
They point away from a positive charge.
They never cross.
Potential Energy=M x G x H
1,568=40 x 10 x H
Now we isolate the H
h=3.92m
