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

or the displacement as a function of time at a point 2.50 m from that end. Assume that no wave bounces back from the other end. Express your answer in millimeters in terms of t.

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}).

The efficiency of a carnot cycle is 1/6. If on reducing the temperature of the sink 75 degree Celsius, the efficiency becomes 1/
svp [43]

Answer:

375 and 450

Explanation:

The computation of the initial and the final temperature is shown below:

In condition 1:

The efficiency of a Carnot cycle is \frac{1}{6}

So, the equation is

\frac{1}{6} = 1 - \frac{T_2}{T_1}

For condition 2:

Now if the temperature is reduced by 75 degrees So, the efficiency is \frac{1}{3}

Therefore the next equation is

\frac{1}{3} = 1 - \frac{T_2 - 75}{T_1}

Now solve both the equations

solve equations (1) and (2)

2(1 - T_2/T_1) = 1 - (T_2 - 75)/T_1\\\\2 - 1 = 2T_2/T_1 - (T_2 - 75)/T_1\\\\ = (T_2 + 75)/T_1T_1 = T_2 + 75\\\Now\ we\ will\ Put\ the\ values\ into\ equation (1)\\\\1/6 = 1 - T_2/(T_2 + 75)\\\\1/6 = (75)/(T_2 + 75)

T_2 + 450 = 75

T_2 = 375

Now put the T_2 value in any of the above equation

i.e

T_1 = T_2 + 75

T_1 = 375 + 75

= 450
