If the eyepiece of a compound microscope has a magnification power of 10X and the objective lense has a magnification power of 4
aleksandrvk [35]

Answer:

Total magnification of microscope at this setting is 40X

Step-by-step explanation:

Total magnification of microscope is determined by multiplying the magnification power of individual lenses.

So if eyepiece has magnification power of 10X and objective lense has magnification power of 4X , the total magnification of microscope would be

10 × 4 = 40

which means the object will appear 40 times larger than actual object.

The distance from the owl to the squirrel would be found by using the law of sins/co-sins

Cos (known angle) = adjacent leg / hypotenuse ( distance wanted)

cos(50) = 14 / x

x = 14 / cos50

x = 21.78 feet

 The problem doesn't say if the answer should be rounded or not. You may have to round the answer if needed.

The product of two fractions is 2/3. One fraction is 3/5. what is the other fraction
Lady bird [3.3K]

Answer:

10 / 9

Step-by-step explanation:

Let's suppose the other fraction is x. We are given 3 / 5 * x = 2 / 3

We can divide by 3 / 5 on both sides, which is the same as multiplying 5 / 3 on both sides:

5 / 3 * 3 / 5 * x = 2 / 3 * 5 / 3

This simplifies to:

x = 10 / 9

Given any triangle in the plane, associate to each side an outward pointing normal vector of the same length as the side. Show t
Zigmanuir [339]

Let , a, b and c be the length of three sides of triangle, represented in terms of vectors as \vec{a},\vec{b},\vec{c}.

Now, vector of same Magnitude acts as normal vector to each side.

So, equation of any vector p having normal q is given by

      \vec{p} \times\vec{q}

Now sum of three vector and it's normal is given as

    =\vec{a} \times\vec{a}+\vec{b} \times\vec{b}+\vec{c} \times\vec{c}\\\\=0+0+0\\\\=0

Cross product of two identical vectors is Zero.

\rightarrow \vec{i} \times\vec{i}=0
