Answer:

77.625 cm

Explanation:

The given distance of the image behind the convex mirror, v = 11.5 cm

The focal length of the mirror, f = 13.5 cm

The mirror formula for convex mirror is given as follows;

\dfrac{1}{u} - \dfrac{1}{v} = -\dfrac{1}{f}

Where;

u = The distance from the statue to the mirror

Therefore, we get;

\dfrac{1}{u} = -\dfrac{1}{f} + \dfrac{1}{v}

Plugging in the values gives;

\dfrac{1}{u} = -\dfrac{1}{13.5} + \dfrac{1}{11.5} = \dfrac{8}{621}

∴ The distance from the statue to the mirror, u = 621/8 cm = 77.625 cm.

xxMikexx [17]

It will take 10000ms

For N = 100 input size

∴ N^2 = 10000 steps and the running time is 1.0 ms.

For N = 10000 input size

∴ N^2 = 100000000 steps are required and running time is

(100000000*1.0)/10000 = 10000 ms is the required running time for execution.

An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware- or software-based routines.

who brought astronomy out of the dark ages by declaring: "finally we shall place the sun himself at the center of the universe.
solong [7]

Nicolaus Copernicus was the one who brought astronomy out of the dark ages.

In one of his books "On the Revolutions of the Heavenly Bodies", he published the renowned line which declares his theory.

Nicolaus Copernicus, A polish astronomer put forward the theory that the is th Sun one that rests in the middle or center of the Universe and the planet Earth revolves around it on its axis every day.which was considered to be called the Heliocentric system.

1) Use SolidWorks (SW) FEA to apply a bending load of 600 lbf on the right end of the stepped shaft as shown below. This is the
salantis [7]

Solution :

Given :

L = 1 in

d = 0.75 in

D = 1 in

Fillet radius, r = 0.063 in

$K_{t_{bending}=\frac{\sigma_{FEA_{bending }}}{\sigma_{Nominal_{bending }}}$

We know that :

$\sigma_{b} = \frac{32M}{\pi d^3}$

$\sigma_{b} = \frac{32 \times (2998.63 \times 25.4)}{\pi (0.75 \times 25.4)^3}$

    $=112.27 \ N/mm^2$

$\sigma_{FEA} = 1.3 \times 10^8 \ N/m^2$

         $=1.3 \times 10^8 \times 10^{-6}$

         $=1.3 \times 10^2$   MPa

         = 130 MPa

Therefore, the stress concentration factor is :

$k_t=\frac{130}{112.27}$

   = 1.157922

The formula d = 1.1 t 2 + t + 1 expresses a car's distance (in feet to the north of an intersection, d , in terms of the number
Phantasy [73]

d(t) = 1.1t² + t + 1

The constant speed required to cover the same distance between t = 3 to t = 5 is the same as the average speed over that same time interval. It is given by:

v = Δx/Δt

v = average speed, Δx = change in distance, Δt = elapsed time

Given values:

Δx = d(5) - d(3) = 19.6ft

Δt = 5s - 3s = 2s

Plug in and solve for v:

v = 19.6/2

v = 9.8ft/s
