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.
The gravitational force on the woman is A) 500 N
Explanation:
There are two forces acting on the woman during her fall:
- The force of gravity, , acting downward
- The air resistance, , acting upward
According to Newton's second law, the net force acting on the woman is equal to the product between the woman's mass and her acceleration:
where m is the mass of the woman and a her acceleration.
The net force can be written as
Also, we know that the woman falls at a constant velocity (5 m/s), this means that her acceleration is zero:
Combining the equations together, we get:
which means that the magnitude of the gravitational force is equal to the magnitude of the air resistance:
