Answer:
Δx = 6.33 x 10⁻³ m = 6.33 mm
Explanation:
We can use the Young's Double Slit Experiment Formula here:
where,
Δx = distance between consecutive dark fringes = width of central bright fringe = ?
λ = wavelength of light = 633 nm = 6.33 x 10⁻⁷ m
L = distance between screen and slit = 3.7 m
d = slit width = 0.37 mm = 3.7 x 10⁻⁴ m
Therefore,
<u>Δx = 6.33 x 10⁻³ m = 6.33 mm</u>
If you let a friend ride with you, increasing the mass does increase the net force on the system, but it also increases the inertia. a=Fnetm. Since both the net force and mass are increased they still cancel, leaving the acceleration the same.
<h3>Further explanation </h3>Inertia is the tendancy of a moving object to keep moving in a straight line or of any object to resist a change in motion.
According to the picture below, we choose x-direction parallel to the inclined surface. Our positive direction is to the right. Hence, we will calculate the acceleration when riding solo first:
Put into
From the equation 3, we found that the acceleration does not depend on the mass of the object. Notice that:
is constant
is constant,
is constant
So that, is constant whatever the amount of the mass is
