The len() function counts the total number of key/value pairs stored in a dictionary and returns this value as an integer.

1 answer:

4 0

The statement is True. The len() function counts the total number of key/value pairs stored in a dictionary and returns this value as an integer.

The entire numbers are set of actual numbers that consist of 0 and all effective counting numbers. while, excludes fractions, terrible integers, fractions, and decimals. all the whole numbers are also integers because integers encompass all the positive and negative numbers.

The integers are the set of complete numbers and their opposites. Fractions and decimals are not included in the set of integers. for instance, 2,5, 0,−12,244,−15, and 8 are all integers. The numbers include eight. five,23, and 413 are not integers.

A variety that isn't a whole variety, a negative whole number, or zero is defined as Non-Integer. it's miles any quantity that isn't always protected in the integer set, that is expressed as { … -4, -three, -2, -1, zero, 1, 2, three, four… }. some of the examples of non-integers consist of decimals, fractions, and imaginary numbers.

Aleonysh [2.5K]

Answer:

The paper focuses on the biology of stress and resilience and their biomarkers in humans from the system science perspective. A stressor pushes the physiological system away from its baseline state toward a lower utility state. The physiological system may return toward the original state in one attractor basin but may be shifted to a state in another, lower utility attractor basin. While some physiological changes induced by stressors may benefit health, there is often a chronic wear and tear cost due to implementing changes to enable the return of the system to its baseline state and maintain itself in the high utility baseline attractor basin following repeated perturbations. This cost, also called allostatic load, is the utility reduction associated with both a change in state and with alterations in the attractor basin that affect system responses following future perturbations. This added cost can increase the time course of the return to baseline or the likelihood of moving into a different attractor basin following a perturbation. Opposite to this is the system's resilience which influences its ability to return to the high utility attractor basin following a perturbation by increasing the likelihood and/or speed of returning to the baseline state following a stressor. This review paper is a qualitative systematic review; it covers areas most relevant for moving the stress and resilience field forward from a more quantitative and neuroscientific perspective.

According to the photon energy formula, tripling the frequency of the radiation from a monochromatic source will change the ener

Harrizon [31]

Answer:

By a factor of 3

Explanation:

In the photon energy formula , frequency and the energy content have a direct relationship. This means anything that is done to one of the parameters is the same that will be done to the other to have a balance.

In this equation: Energy=plank’s constant * frequency.

Energy is directly proportional to frequency.

A hockey player skates with an average speed of 8.25 m/s. The distance the player will travel in 5.60 s is __________ .

OverLord2011 [107]

<h2>Greetings!</h2>

To find this value, you need to remember the speed formula:

3 = 6 / 2

Speed = distance ÷ time

Rearrange to make distance the subject:

Distance = speed * time

Simply plug these values into this:

5.6 * 8.25 = 46.2

<h3>So the player will travel 46.2 metres!</h3>
<h2>Hope this helps!</h2>
