sawdust float in water so you could dump the mixture in water so that all of the sawdust float on the surface while the nails sink to the bottom.
FALSE! You would still need to complete, just in case they accepted
65% would be ur answer
hope it helps
A)
2revs in 0.08s
so in 1s thats 25revs
therefore thats <u>50π radians</u> in one second
b)
well, ω=2π/T
therefore ω=50π = 157.079rads^-1
and v=rω where r is in meters;
v=0.3x157.079
<u>v=47.123ms^-1</u>
c)
f=1/T
f=1/period for one rotation
1 rotation = 0.08/2 = 0.04
f=1/0.04
<u>f=25Hz</u>
Because it on by it's self floating around not forming part of something
