(1) Filtration - example is separating saltwater from sand particles.
(2) Distillation - example is apple cider vinegar. Distillation collects the liquid that we want, which is the vinegar and leave out other heavier suspended particles.
(3) Centrifuges - example is separating the blood components. They separate the plasma and erythrocytes.
(4) Magnetism - example is separating metals from non-metals in electromagnetic cranes, that differentiate between metal and heap of junks.

A mass M is suspended from a spring and oscillates with a period of 0.840 s. Each complete oscillation results in an amplitude r
iren [92.7K]

The energy becomes 0.50 times in 6.72 s.

Let E represent the oscillator's initial energy, Et be the energy's final value at time t, where A is its beginning amplitude, At amplitude at time t, be. as the oscillator's energy increases to 0.50 times its initial value. We can replace the oscillator's total energy for the energy at time t to obtain the amplitude as shown below.

Et=0.50E

1

k(4₂)² = (0.5) - kA²

(4₂)² = (0.5) A²

At = 0.71A

So, the amplitude of the oscillator becomes 0.71 times its initial ar

0.71A = = A(0.96)¹2

log(0.71)

log(0.96)

8.4

n=

So, the time taken for n oscillation is obtained as,

t = n (0.800 s)

= (8.4) (0.800)

= 6.72 s
