For the lengths of its sides
As a scalene triangle (from the Greek σκαληνός "unequal"), if all its sides have different lengths (in a scalene triangle there are no two angles having the same measure)
For its angles
obtuse triangle: if one of its interior angles is obtuse (greater than 90 °); the other two are acute (less than 90 °).
Answer: 4.675×10^-6 m
Explanation: this is a question under the pattern gotten from an interference experiment.
The formulae below defines the experiment given
y = Rmλ/d
Where y = distance between the center fringe and any other fringe in the pattern = 8cm = 0.08m
m = position of fringe = 1 ( this is because we have only one central band)
λ = wavelength of light used for experiment = 680nm = 6.8×10^-7m
d = width of slit =?
R = distance between slits and screen = 5.5 cm = 0.055m
By substituting the parameters, we have that
0.08 = 0.055 × 1 × 6.8×10^-7/d
By cross multiplying, we have that
0.08 × d = 0.055 × 1 × 6.8×10^-7
d = 0.055 × 1 × 6.8×10^-7/ 0.08
d = 3.74 × 10^-7/ 0.08
d = 46.75×10^-7
d = 4.675×10^-6 m

i dont know but i should know try g o o g l e
Explanation:
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 )
