Answer:
6.77 m/s
Explanation:
Acceleration = Force/mass;
The block is accelerated by 13/6.4 m/s^2 for 2.1s from an initial velocity of 2.5m/s.
Applying the equation of motion:
Vf=Vi + at
Where Vf is the final velocity, Vi is the initial velocity, a is the acceleration and t is the time for which the object accelerates.
<h3>Vf= 2.5 + ((13/6.4)*2.1);</h3>

Answer:
Option C. Its image falls on the periphery of the retina, denser in rods
Explanation:
This can be explained as the photo receptors present in the outer periphery are more sensitive to light and enable us to see clearly dimly lit objects.
Also the peripheral vision is the the one on the retinal periphery which is highly rich in concentration of rods than cones and thus a dimly lit object at night with peripheral vision gives a clearer image of the object.
The central vision makes use of the central part, i.e., fovea which is dense with the concentration of cones, photo-receptors which enable us to see different colors and functions well in bright light.
