Answer:
0.541 nm
Explanation:
The condition for maxima is,
Here, m=0,1,2,.....
And d is the slit separation, m is the order of maxima, 
is the wavelength.
Given that, the 17.3 eV electron posses a wavelength of
And the order of maxima is 
.
And the angle at which first order maxima occur is, 
.
Put these values in maxima condition while solving for d.
Therefore, the slit separation is 0.541 nm.
Work = (force) x (distance)
To lift each baby, force = 90N,
distance = 1.0 something, let's say 1.0 meter .
Work to lift each baby = (90N) x (1.0 meter) = 90 joules.
Work to lift both of them = 2 x 90 joules = 180 joules.
The left end of the string is given as y = - 0.100 sin (3.14t )
<h3>How to find the sinusoidal wave</h3>
We would have to create an equation of this form
The wave function equation
y = A sin ( π*x - ω* t )
When we put in the values that we have in the equation
y = 0.100 sin ( 3.14 x - 3.14 t )
Due to the fact that it is the left end of the string, the value that we would have for x is going to be 0, hence we would have
y = 0.100 sin (3.14 * (0) - 3.14t )
Then y would be 0.100 sin (- 3.14t )
This would give us the final equation
y = - 0.100 sin (3.14t )
Hence we would have the left end of the string as y = - 0.100 sin (3.14t )

<h3>Speed between point A and B</h3>
= Total Distance/Total time
= 30/3
= 10 km/h
<h3>Average speed for this ride</h3>
Average speed = Total distance travelled/time taken
= 50/6
= 8.3 km/h
