Answer:
The telescope can gather light 1600 times more than the human eyes can!
Explanation:
The light gathering ability of an optical element is directly proportional to its area of opening.
So, in comparing the light gathering abilities for two objects, it is just the ratio of their area of opening.
Let the diameter of the telescope be D = 1 m
And the diameter of the human eyes be d = 2.5 cm = 0.025 m
Light gathering ability of the telescope compared to the eyes = D² ÷ d²
= (D²/d²) = (1²/0.025²) = 1600 times.
The telescope can gather light 1600 times more than the human eyes can!
Hope this Helps!!!
Answer:
I think it is velocity.
because velocity shows the direction and magnitude .

Answer:
correct option is a. 0.2 mA toward D
Explanation:
given data
B carries = 1.5 mA
C carries current = 1.3 mA
solution
we take positive direction of current going away from the point D
and negative direction of current coming towards point D
so we use here kirchoff's current law
that is
iA + iB + iC = 0 ......................1
iA + 1.5 + (-1.3) = 0
iA = - 0.2 mA
so that current in wire A is 0.2 mA towards point D
correct option is a. 0.2 mA toward D
