The shutter speed that should be used if the lens is changed to f/4.0 is; Choice D: 1/500 s.
The relationship between the shutter speed and the focal ratio is an inverse relationship.
Ratio of Areas = 5.6²/4²
Since; T1A1 = T2A2
- T2 = 250 × 2 = 500 seconds
In essence; when the focal ratio is reduced as in this case; from f/5.6 to f/4.0; the shutter speed is increased.
Ultimately, the shutter speed of the camera in discuss increases to; 1/500 s.

"The table represents the speed of a car in a northern direction over several seconds. Column 1 would be on the x-axis, and Column 2 would be on the y-axis."
typical plot is speed or velocity on the y-axis n time on the x-axis so the ans is Column 1 should be titled “Time,” and Column 2 should be titled “Velocity.”
Answer:
Two wave will be coherent when they have the wavelength, amplitude, and phase of the constituent wave forms must be identical.
Where as interference is the addition of two wave considering the mathematical sense while adding them.
when two wave of same sense add together they for constructive interference. like two +ve sense or -ve sense will form constructive interference.
when the are are of different sense the form destructive interference. like one positive wave added with -ve one.
No. Because the color of the apple is red.
Answer:
kinematics is the branch of mechanics concerned with the motion of objects without reference to the forces which cause the motion.
the features or properties of motion in an object.
