No problem. After you turn on 2-Step Verification, non-browser applications and devices that use your Google Account (such as Outlook), may be unable to connect to your account.If you sign in from another computer, however, you’ll be asked for your 2nd form of verification. Every 30 days or every time you try logging into your SUSD Google Mail or any Google Single Sign On service on a new device, you’ll be sent a push notification to your phone, asked for a six-digit code (also sent to your phone), or prompted to insert your hardware key, depending on which option you chose during initial set-up. If you want, when you enter your verification, you can choose to trust your computer - this means you won't be asked for a code again when you sign in from this computer.Go to the sign-in page of your mail or any other SUSD Google application that employs Google Single Sign-On, and enter your username and password like you normally do.Signing in with 2-Step Verification is easy. How do I sign in with 2-Step Verification? We recommend you choose at least one alternative option. You also have the option of using a Security Key for 2-Step Verification or a variety of other alternative second steps. The next time you sign in, you'll receive a message with a verification code. Review your settings and add backup phone numbers. Once you're finished, you'll be taken to the 2-Step Verification settings page.

Go to your Google Account's 2-Step Verification page.You sign in with something you know (your password) and something you have (like a code sent to your phone). When you enable 2-Step Verification (also known as two-factor authentication), you add an extra layer of security to your account. Here's why this matters: In most cases you would have no way of knowing whether someone somewhere else in the world had cracked your password and was rummaging through your account. With 2-step verification enabled, they would need the password and physical control of your phone, your wallet or purse, or your actual computer. Without setting up 2-step verification, hackers could get into your account if they figured out your password. You should set up 2-step verification because doing so makes it very hard for anyone to take over your email account remotely. Google 2-Step Verification Frequently Asked Questions (FAQ) 2-Step Verification Basics The isotope of a given element is defined by adding the number of protons and neutrons in its nucleus. Atoms of the same element that have a different number of neutrons are called isotopes. Let us now learn the difference between atomic number and atomic mass of elements.īefore going into atomic mass, it is essential to learn about isotopes. This was the atomic mass of the first 30 elements. Given below is the atomic mass of elements list. Let us take a look at what is the atomic mass of elements from 1 to 30. In the same group, a periodic repetition of properties can be seen in the elements with increasing mass. Similarly, the elements in Group 8A are unreactive gaseous at room temperature. For example, the elements in Group 1A are mostly soft metals that are highly reactive with water. Elements that have similar qualities fall into the same column or group. When observing the periodic table, one can see that elements are arranged on the basis of increasing atomic numbers. The number of electrons in an element considerably determines the chemical behaviour of the element. The atomic number is important because the number of protons determines the number of electrons that surround the nucleus. Atoms of all elements have neutrons in the nucleus except hydrogen. Neutrons are uncharged subatomic particles which are stable when bound in an atomic nucleus. Elements are identified based on the number of protons in the nucleus regardless of the number of neutrons present. The atomic number gives a number of how many protons are inside the nucleus of the atom. The overall atomic masses that are given in periodic tables like the one for hydrogen are determined for the naturally occurring isotopes of each element, weighted by the weight of those particular isotopes on earth. Every isotope's contribution to the normal is controlled by how huge a fraction of the example it makes up. The general atomic mass is the normal of the atomic masses of the apparent multitude of various isotopes in an example. Since an element's isotopes have distinctive atomic masses, researchers may likewise decide the general atomic mass-once in a while called the atomic weight-for an element. The atomic mass number is usually rounded off to the nearest whole number. For example, a normal carbon atom with six neutrons and six protons is denoted as carbon-12. The atomic mass of a solitary atom is its absolute mass and is regularly expressed in atomic mass units or amu. Since we have seen the definition of atomic mass let us discuss it in detail. In this article, we will learn about the following things: the atomic mass of elements in detail, what is the atomic mass of all elements, and what is the atomic number and atomic mass of elements. An interesting point to note is that it is also referred to as atomic weight. The atomic mass is simply defined as the weighted average of all of the isotopes of an element, in which the mass of each isotope is multiplied by the abundance of that particular isotope. The atomic mass in Chemistry is the average mass of the atoms of an element measured in atomic mass units (amu).

The effect will be the same as clicking each card. You can use super moves to make your game playing more efficient.Ĭlicking or dragging a card that isn't immediately accessible will attempt to move all the cardsĪbove it in its stack until the move is valid. If this is not achieved, the game ends after the entire stock has run out. The game is won when all cards are built onto the foundations. A card that cannot be built on the tableau or on the foundations is placed on the waste pile, the top card of which is available for play. When no more cards can be moved, the stock (the remaining cards) is dealt one card at a time. A sequence or part of a sequence can be moved as a unit. The top cards of each column are available for play, to be built up by suit on the foundations, or on each other down by alternating colors. The object of the game is to release the Aces as they become available, creating foundations, and to then build up each suit from the Ace. This results in an alternating OXOXOXO pattern. The second, fourth, and sixth cards from the top are face down. In each column, the top card, the third and fifth cards from the top and the bottom card are face up. Alternation is a solitaire card game which is played using two decks of playing cards.įorty-nine cards are set up into seven columns of seven cards each. If pounds and inches are used, a conversion factor of 703 (kg/m 2)/(lb/in 2) is applied. The BMI is expressed in kg/m 2, resulting from mass in kilograms and height in metres. Additional metrics, such as waist circumference, can be more useful. Nevertheless, due to its simplicity, it has come to be widely used for preliminary diagnoses. Keys explicitly judged BMI as appropriate for population studies and inappropriate for individual evaluation. The interest in an index that measures body fat came with observed increasing obesity in prosperous Western societies. In this paper, Keys argued that what he termed the BMI was "if not fully satisfactory, at least as good as any other relative weight index as an indicator of relative obesity". The modern term "body mass index" (BMI) for the ratio of human body weight to squared height was coined in a paper published in the July 1972 edition of the Journal of Chronic Diseases by Ancel Keys and others. According to Lars Grue and Arvid Heiberg in the Scandinavian Journal of Disability Research, Quetelet's idealization of the average man would be elaborated upon by Francis Galton a decade later in the development of Eugenics. Quetelet thought of the average man as a social ideal, and developed the body mass index as a means of discovering the socially ideal human person. Instead, it was a component of his study of l'homme moyen, or the average man. Quetelet himself never intended for the index, then called the Quetelet Index, to be used as a means of medical assessment. Īdolphe Quetelet, a Belgian astronomer, mathematician, statistician, and sociologist, devised the basis of the BMI between 18 as he developed what he called "social physics". When used to predict an individual's health, rather than as a statistical measurement for groups, the BMI has limitations that can make it less useful than some of the alternatives, especially when applied to individuals with abdominal obesity, short stature, or high muscle mass.īMIs under 20 and over 25 have been associated with higher all-cause mortality, with the risk increasing with distance from the 20–25 range. Major adult BMI classifications are underweight (under 18.5 kg/m 2), normal weight (18.5 to 24.9), overweight (25 to 29.9), and obese (30 or more). The BMI is a convenient rule of thumb used to broadly categorize a person as based on tissue mass ( muscle, fat, and bone) and height. The table may also show contour lines or colours for different BMI categories. The table displays BMI as a function of mass and height and may show other units of measurement (converted to metric units for the calculation). The multiplication and division may be carried out directly, by hand or using a calculator, or indirectly using a lookup table (or chart). The BMI may be determined first by measuring its components by means of a weighing scale and a stadiometer. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m 2, resulting from mass in kilograms (kg) and height in metres (m). Body mass index ( BMI) is a value derived from the mass ( weight) and height of a person. It is much easier to work with a loss of 137 dB rather than the equivalent factor of 2 x 10-14 mW – a number that cannot be easily manipulated.īetter still, instead of multiplying gain or loss factors as percentages, by using dB measurement we can add them as positive or negative dB values. The dB is very useful when describing signal loss due to radiation through the atmosphere. For instance, if 10 watts of power is fed into a cable but only 8.5 watts are measured at the output, the signal has been decreased by a factor ofĪn attenuator, cable or optical path that reduces its input power by factor of 0.001 has an attenuation of 30 dB or a gain of -30 dB. (notice the 3 in 30 dB corresponds to the number of zeros in the power ratio)Ĭonversely, a ratio of less than 1.0 is a loss, a negative gain, and will be expressed as a negative dB value. Consider an amplifier with an output of 100 watts when the input is 0.1 watts (100 milliwatts) The logarithmic characteristic of the dB makes it very convenient for expressing power ratios. Logarithmic Power Measurements for Wireless Links Decibel Attenuation Millimeter Wave MMW Spectrum One milliwatt output power is then zero dBm. The abbreviation dBm indicates dB referenced to 1.0 milliwatt. The most common references in the world of electronics are the milliwatt (mW) and the watt. It is often desirable to express power levels in decibels by using a fixed power as a reference. The term decibel does not in itself indicate power, but rather is a ratio or comparison between two power values. For example, if P2 is one-tenth of P1, we have: If P2 is less than P1, the ratio is less then 1.0 and the resultant (exponent) value is negative. In this equation, P1 is usually the reference power. With the constant almost always included in modern terminology and power referred to as a “ten log” function. Usually a smaller unit, the Decibel or dB, is used. Since the bel is a rather large unit, it is not useful for precise measurements. The exact relationship is given by the formula Bels = log(P2/P1), where P2/P1 represents the power ratio. As originally used, the bel represented the power ratio of 10 to 1 between the strength or intensity of two sounds, and was named after Alexander Graham Bell.īels represents a logarithmic relationship since the (common log) logarithm of 100 (to the base 10) is 2 (corresponding to 2 bels), the logarithm of 1000 to the base 10 is 3 (corresponding to 3 bels), etc. The Decibel is a sub-unit of a larger unit called the bel. Wireless link designers – just as with Fibre Optics – use Decibels to calculate power transmission losses and link budgets.
