REPETITION CYCLES. A repeating structure allows you to execute an instruction or a set of instructions multiple times. A repetitive execution of sentences is characterized by: The sentence or sentences that are repeated. The cycle is one of the most important basic programming structures, as it is present in dissimilar problems. In structured programming there are three types of basic cycles: determined, indeterminate avoidable, and indeterminate unavoidable; On the other hand, visual programming brings with it a revolutionary change in this structure, since the user who controls when the cycle ends is himself, activating an event that signifies the breaking of the cycle.

A 15.0-mW laser puts out a narrow beam 2.00 mm indiameter.

UkoKoshka [18]

Explanation:

It is known that formula for energy per unit area per unit time is as follows.

S = $\frac{P}{A}$

= $\frac{P}{\pi \times r^{2}} = \frac{4P}{\pi d^{2}}$

$c \epsilon_{o} E^{2} = \frac{4P}{\pi d^{2}}$

E = $\sqrt{\frac{4P}{\pi d^{2} c \epsilon_{o}}}$

Now, putting the values we will calculate the electric field as follows.

E = $\sqrt{\frac{4P}{\pi d^{2} c \epsilon_{o}}}$

= $\sqrt{\frac{4 \times 15 \times 10^{-3} W}{3.14 \times (2mm \times \frac{1m}{1000 mm})^{2} \times 3 \times 10^{8} \times 8.85 \times 10^{-12}}}$

= 1341.03 V/m

Now, we will calculate the average magnetic field as follows.

B = $\frac{E}{c}$

= $\frac{1341.03 V/m}{3 \times 10^{8} m/s}$

= $4.47 \times 10^{-6}$ T

= $4.47 \mu T$

Thus, we can conclude that the average (rms) value of the magnetic field is $4.47 \mu T$ .

A 150 g air-track glider is attached to a spring. The glider is pushed in 8.80 cm and released. A student with a stopwatch finds

Alla [95]

Answer:

2.06 N/m

Explanation:

The system makes 10.0 complete oscillations in 17.0 s. So, the frequency of the system is

$f=\frac{10.0}{17.0 s}=0.59 Hz$

The angular frequency of the system is given by

$\omega = 2\pi f=2\pi (0.59 Hz)=3.71 rad/s$

In a simple harmonic motion, the angular frequency is related to the mass and the spring constant by

$\omega=\sqrt{\frac{k}{m}}$

where

k is the spring constant

m is the mass

Here we know

$\omega=3.71 rad/s\\m = 150 g = 0.150 kg$

So we can solve the formula to find k:

$k=\omega^2 m = (3.71 rad/s)^2 (0.150 kg)=2.06 N/m$

You look in the sky and see two jetliners that you know are of equal size, yet one appears to be much larger. Because of your kn

Ksju [112]

Answer:

Because of the knowledge of <u>relative size</u>, it will be assumed that the smaller jetliner is farther away.

Explanation:

According to the theory of relative size, the distance that an object has to the viewing individual affects the perception of the individual regarding the size of the object.

As stated in this case, one of the jetliners is farther away from the other. Therefore, even if the jets are of equal size, the one that is at a greater distance is perceived to be smaller as it is at a greater viewing range. The one that is nearer to the individual seems bigger in comparison to the one farther away due to a closer viewing range.

Therefore, the jet that is nearer appears larger.
