The bigger the mass of an astronomical object the bigger the depression it causes in the space-time fabric. Any other astronomical object that gets closer to this depression begins to fall into the depression and hence accelerates closer to the astronomical object causing the depression. This is how gravity is felt.

The dark fringe for m = 0 in a young's double-slit experiment is located at an angle of θ = 15°. What is the angle that locates

Ad libitum [116K]

The dark fringe for m = 0 in a young's double-slit experiment is located at an angle. The angle that locates the dark fringe for m = 1 is 51°.

<h3>What is dark fringe?</h3>

When light passes through a slit , it produces a spectrum which can be seen on the screen kept a distance in form of fringes of different intensity. The fringe with intensity zero is called the dark fringe.

Given is the angle θ = 15°

The equation for the dark fringe is

d sinθ = (m + 1/2)λ

For m= 0 and m=1, the ratio of the sines is

sinθ₁/sinθ₀ = [(m + 1/2)] / [(m + 1/2)]

Rearranging for sinθ₁, we have

sinθ₁ = [(m + 1/2)] / [(m + 1/2)] (sinθ₀)

Substituting the values into the equation and solving for θ₁

sinθ₁ = [1+1/2]/[0+1/2] (sin15)

θ₁ = 51°

Thus, the angle that locates the dark fringe fro m = 1 is 51°.

Wind resistance _____ as speed increases.

Over [174]

The correct option is option B that wind resistance increases dramatically.

Explanation:

When the speed of an object increases resistance increases drastically because the object pushing through air has obtained a high speed but the air is unable to move out of the way so fast so show it tends to get compressed and oppose the moving object and the object names to put more pressure because some of the pressure goes into cutting air and moving through it.

Question 6 (10 points)

horsena [70]

Answer:

a= g = - 9.81 m/s2.

The following equations will be helpful:

a = (vf - vo)/t d = vot + 1/2 at2 vf2 = vo2 + 2ad

When you substitute the specific acceleration due to gravity (g), the equations are as follows:

g = (vf - vo)/t d = vot + 1/2 gt2 vf2 = vo2 + 2gd

If the object is dropped from rest, the initial velocity ("vi") is zero. This further simplifies the equations to these:

g = vf /t d = 1/2 gt2 vf2 = 2gd

The sign convention that we will use for direction is this: "down" is the negative direction. If you are given a velocity such as -5.0 m/s, we will assume that the direction of the velocity vector is down. Also if you are told that an object falls with a velocity of 5.0 m/s, you would substitute -5.0 m/s in your equations. The sign convention would also apply to the acceleration due to gravity as shown above. The direction of the acceleration vector is down (-9.81 m/s2) because the gravitational force causing the acceleration is directed downward.

hope this info helps you out!
