You perform a double‑slit experiment in order to measure the wavelength of the new laser that you received for your birthday. Yo

u set your slit spacing at 1.15 mm and place your screen 9.39 m from the slits. Then, you illuminate the slits with your new toy and find on the screen that the tenth bright fringe is 4.55 cm away from the central bright fringe (counted as the zeroth bright fringe). What is your laser's wavelength expressed in nanometers?

Answer:

557.24nm

Explanation:

m λ = dsinθ

d = 1.01 x 10e-3   m=10

we use tanθ because of the long distance

so d (x/R) = m λ    x = distance from central fringe and R = distance from screen

(1.15x10e-3)[(4.55x10e-2)/(9.39)] = 10 λ

5.5724x10e-6 m or 557.24nm

A solid ball is released from rest and slides down a hillside that slopes downward at an angle 51.0 ∘ from the horizontal. what
Romashka [77]
In order for the object not to slip, the component of the weight parallel to the surface must be equal to the frictional force (which acts in the opposite direction):
F_{//}= F_a

The parallel component of the weight is:
F_{//} = mg \sin \alpha
where m is the object mass and \alpha is the angle of the inclined plane.

The frictional force is
F_a = \mu m g \cos \alpha
where \mu is the coefficient of static friction.

Equalizing the two forces, we have
mg \sin \alpha = \mu m g \cos \alpha
from which we find
\mu =  \tan \alpha

and so, in our problem the coefficient of static friction must be
\mu=\tan 51^{\circ} =1.23

An object moving north with an initial velocity of 14m/s accelerates 5m/s squared for 20 seconds. What is the final velocity of
Gemiola [76]

Since it moves 5 m/s faster every second, after 20 seconds it's moving 100 m/s faster than when it started speeding up.

If it was moving at 14 m/s when the acceleration began, it's moving at 114 m/s at the end of the 20 seconds.  Its velocity is <em>114 m/s North.</em>

That's 255 mph !

What do u mean by free fall?​
Degger [83]

Answer:

Any motion of a body in which gravity is the sole force acting on it is known as free fall. A body in free fall has no force acting on it under general relativity, where gravity is reduced to space-time curvature.
