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
Answer:
Explanation:
The formula for the surface of the circle is:
The rate of change of the spill area is obtained by deriving the previous formula in terms of time:
Finally, variables are replaced by known data:
Answer:
B
Explanation:
OOf we are doing this stuff atm
So if its faster at the front and slow at the back you can tell that its not slowing down because less of a force is there however at the front there is more of a force. Friction is low which means that its not makimg much contact so no sudden change of forces thats also why its B
It transforms it to mechanical
Answer:
T₂ = 1937.68 N
Explanation:
First, we will calculate the weight of the object:
Now, we will calculate the resultant tension in the ropes. Since the ropes are perpendicular. Therefore,
where,
T = Resultant Tension
T₁ = Tension in rope 1
T₂ = Tension in rope 2
According to the given condition tension in the first rope is 2.2 times the tension in the second rope:
T₁ = 2.2 T₂
Therefore
Now, the weight of the object must be equal to the resultant tension for equilibrium:
<u>T₂ = 1937.68 N</u>
