The answer is B.
t = Vy / g
t =( 19 x sin21 ) / 9.8 = 0.69s
Answer:
Hence the order of the bright fringe is 7.
Explanation:
Diffraction can be defined as the deviation from rectilinear propagation and diffraction grating is used to measuring the wavelength of light using a spectrometer.
We have the formula d sin∅ = n l
We have to find the value of n in this equation and all other values are given.
Here d = 55000 lines
∅ = 12.23°
Wavelength , l = 550 nanometer
n is the order of the bright line.
Substitute these values in the given equation,
55000 sin(12.23°) = n
n = 7
Hence the order of the bright fringe is 7.

Answer:
The function that describe the motion in the time
y (t) = 0.28m * sin ( 36.025 * t)
Explanation:
The angular frequency of oscillation of the spring
w = √k/m
w = √305 N/m / 0.235 kg
w = 36.025 rad / s
To determine the function of the motion knowing as a motion oscillation in a amplitude a frequency
y(t) = A * sin (w t )
So
A = 28.0 cm * 1 m / 100 cm = 0.28 m
So replacing to determine the function of the motion in the time
y (t) = A sin (w t)
y (t) = 0.28m * sin ( 36.025 * t)
