A parallel beam of microwaves is focused on a metal screen that contains 20-cm-wide, horizontal slit. Microwaves have longer wavelength than visible light, and a 20 cm slit is wider than what you would use to observe diffraction from visible light (where the slit would need a width similar to a hair). Microwaves will produce the same type of diffraction pattern as discussed in the background for this Investigation, where the equation

a sin ⁡ θ = n λ , n = ± 1 , ± 2 , ± 3 , e t c

for the resulting diffraction pattern will be valid.

Required:
A detector moving parallel to a screen used to observe the diffraction pattern finds the first minimum at what angle above the axis of the central axis (where the central maximum is) at an angle of 36.87 degrees above the central axis?

Part a determine the magnitude of the x component of f using scalar notation. fx f x = nothing lb request answer part b determine the magnitude of the y component of f using scalar notation. fy f y = nothing lb request answer part c determine the magnitude of the z component of f using scalar notation. fz f z = nothing lb request answer provide feedback figure1 of 1a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component. a force vector acting on a ring attached to the ground is shown in the xyz space together with its x, y, and z components lying on the corresponding positive axes. the ring is located at the origin. force f is located in the first octant. f makes an angle of 60 degrees with its x component and an angle of 45 degrees with its y component.

You and a friend (alex) are at a a tree-top adventure park .. . part of the course requires you to climb up a rope. you both climb the same rope in the same amount of time. however, the tension in the rope is greater when alex climbs. who did the most work? alex did - more tension means more force - more force means more work was done you did - less tension means less force - less force means more work was done to find the work done, the force exerted and distance moved are multiplied. a couch is moved twice before you are happy with its placement. the same force was used to move the couch both times. if more work is done the first time it is moved, what do you know about the distance it was moved? when more work was done, the couch was moved less. when more work was done, the couch was moved further. when more work was done, the couch wasn't moved at all. when more work was done, the couch was moved the same distance.
