<span>c). the binding energy per nucleon must decreases as atomic number increases</span>
Friction is the force that always acts in the opposite direction of the force so, decrease it's magnitude.
That's why, it never speed up an object but always decrease it's speed it up to an extent!
Hope this helps!
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.
