A beam of laser light of wavelength 505 nm passes through a thin slit of width 0.00494 mm. The light then forms a diffraction gradient on a distant screen. What is the smallest angle relative to the original direction of the beam at which destructive interference occurs? a.) ±4.80°

b.)±6.89°

c.)±5.13°

d.)±5.87°

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction 

The cell reaction uses external supplies of a full and an oxidant, which are consumed and needs to be provided continuously. the cell will continue to provide electrical energy so long as there is a supply of fuel and oxidant.  hope this ! (:
