Answer:
A maximum
Explanation:
When displacement is maximum, velocity is Zero and vice versa
When displacement is maximum, acceleration is maximum and when it is zero, acc. Is zero
Answer:
0.990 m/s
Explanation:
Initial energy = final energy
0 = KE + PE
0 = ½ mv² + mgh
0 = ½ v² + gh
0 = ½ v² + (9.8 m/s²) (-0.0500 m)
v = 0.990 m/s
Answer:
The distance between the object is
Explanation:
The free body diagram of this setup is on the first uploaded image
From the question
The diameter of closely packed cones in the fovea of the eye is =
The distance of separation by one cone(not excited ) is
The distance between the two point-like object is l
The diameter of the eye is D = 2 cm
The distance of the two point-like object from the near point of the eye is A = 28 cm
From the diagram we see that the light from the two point-like object form a triangle of similar base l and d and height D and A
So for a triangle with similar base we have that
making l the subject we have
