Answer:
Y = 3.87 x 10⁻³ m = 3.87 mm
Explanation:
This problem can be solved by using Young's double-slit experiment formula:
![Y = \frac{\lambda L}{d}](https://tex.z-dn.net/?f=Y%20%3D%20%5Cfrac%7B%5Clambda%20L%7D%7Bd%7D)
where,
Y = fringe spacing = ?
L = slit to screen distance = 2 m
λ = wavelength of light = 580 nm = 5.8 x 10⁻⁷ m
d = slit width = 0.3 mm = 3 x 10⁻⁴ m
Therefore,
![Y = \frac{(5.8\ x\ 10^{-7}\ m)(2\ m)}{3\ x\ 10^{-4}\ m}](https://tex.z-dn.net/?f=Y%20%3D%20%5Cfrac%7B%285.8%5C%20x%5C%2010%5E%7B-7%7D%5C%20m%29%282%5C%20m%29%7D%7B3%5C%20x%5C%2010%5E%7B-4%7D%5C%20m%7D)
<u>Y = 3.87 x 10⁻³ m = 3.87 mm</u>

Answer:
Object D
Explanation:
Use Newton's Second Law to determine the acceleration that each object has.
The force applied in both cases is 50 N, but the mass for object C and object D is different.
Let's start with object C first:
- F = ma
- 50 N = 10 kg · a
- 50 = 10a
- 5 = a
The acceleration object C undergoes is 5 m/s².
Now let's calculate object D next:
- F = ma
- 50 N = 2 kg * a
- 50 = 2a
- 25 = a
The acceleration object D undergoes is 25 m/s².
Object D has greater acceleration because it has a smaller mass. The object with a smaller mass will accelerate more in order to satisfy Newton's 2nd Law.
The length of a wave so, therefore its D.
