Hi,
My best answer would be Gravity. Is it a multiple choice question? Or is it an essay question.
Answer:
1/f = 1/o + 1 /i thin lens equation
1 / i = 1/f - 1/o = (o - f) / (o f) rearranging
or i = o f / (o - f) for the image distance
This image will be positive (real) with values given
m = -i / o magnification
m = - f / (o - f) shows m is negative and the image inverted
Also, since o here is large m will be small and the image is small
I think they mean A as the right answer
Different texts use different terms but here i is image distance and o the object distance
The choice that would best describe the word "tempo" would be letter A which states that it is "a pace of music or speed of beats per minute." In addition, a tempo is an important characteristic of music because it is the one who carries the emotions and feelings of the composer towards the music he/she makes.
Answer:
It would 110
Explanation:
It is only because of a división leading you into a
Answer:
each resistor is 540 Ω
Explanation:
Let's assign the letter R to the resistance of the three resistors involved in this problem. So, to start with, the three resistors are placed in parallel, which results in an equivalent resistance 
defined by the formula:
Therefore, R/3 is the equivalent resistance of the initial circuit.
In the second circuit, two of the resistors are in parallel, so they are equivalent to:
and when this is combined with the third resistor in series, the equivalent resistance (
) of this new circuit becomes the addition of the above calculated resistance plus the resistor R (because these are connected in series):
The problem states that the difference between the equivalent resistances in both circuits is given by:
so, we can replace our found values for the equivalent resistors (which are both in terms of R) and solve for R in this last equation:
