Why can a device never be 100% efficient? Explain.
sesenic [268]

Answer:

No machine is free from the effects of gravity, and even with wonderful lubrication, friction always exists. The energy a machine produces is always less than the energy put into it (energy input). ... That is why 100% efficiency in machines shall not be possible.

  • P_1=+3D
  • P_2=-2D

\\ \bull\tt\dashrightarrow P=P_1+P_2

\\ \bull\tt\dashrightarrow P=+3D-2D=+1D

Now

\\ \bull\tt\dashrightarrow f=\dfrac{1}{P}

\\ \bull\tt\dashrightarrow f=\dfrac{1}{1}

\\ \bull\tt\dashrightarrow f=1m

At t = 0 the end you are oscillating is at its maximum positive displacement and is instantaneously at rest. Write an equation f
vovikov84 [41]

Answer:

The equation of displacement is y=A\sin(\omega t-2.50 k+\dfrac{\pi}{2}).

Explanation:

Given that,

Distance = 2.50 m

We need to calculate the equation of wave

Using general equation of wave

y=A\sin(\omega t-kx+\phi)....(I)

Where, A = amplitude

t = time

x = displacement

\phi = phase difference

Put the value in the equation

At t = 0, x = 0, y =A

A=A\sin(0+\phi)

\sin\phi=1

\phi=\dfrac{\pi}{2}

From equation (I)

y=A\sin(\omega t-2.50 k+\dfrac{\pi}{2})

Hence, The equation of displacement is y=A\sin(\omega t-2.50 k+\dfrac{\pi}{2}).
