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.

Calculate the number of electrons in a small, electrically neutral silver pin that has a mass of 7.1 g. Silver has 47 electrons

Assoli18 [71]

Answer: The number of electrons in given amount of silver are $1.87\times 10^{24}$

Explanation:

To calculate the number of moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}$

We are given:

Given mass of silver = 7.1 g

Molar mass of silver = 107.87 g/mol

Putting values in above equation, we get:

$\text{Moles of silver}=\frac{7.1g}{107.87g/mol}=0.066mol$

Number of electrons in 1 atom of silver = 47

According to mole concept:

1 mole of an element contains $6.022\times 10^{23}$ number of particles

So, 0.066 moles of silver will contain = - $(0.066\times 47\times 6.022\times 10^{23})=1.87\times 10^{24}$ number of electrons

Hence, the number of electrons in given amount of silver are $1.87\times 10^{24}$

The law of reflection says that the angle of incidence is

nekit [7.7K]

The law of reflection states that the angle of incidence is equal to the angle of reflection. Furthermore, the law of reflection states that the incident ray, the reflected ray and the normal all lie in the same plane.

hope this helps :)

Through which type of media do mechanical waves, such as sound, move the fastest?

monitta

Mechanical waves travel the fastest in solids and liquids because the molecules are more closely packed together than gases, so energy is transferred from one particle to another particle faster.

A particle R moves with a velocity of 6 m/s due East and another particle S moves at 8 m/s due South. What is the magnitude of t

cluponka [151]

Answer:

Explanation:

We can look at this problem as a triangle, r is the hypotenuse so if we take the square root of 6^2+8^2 we get 10

What is the acceleration of a ball traveling horizontally with an initial velocity of 20 meters/second and, 2.0 seconds later, a

Nutka1998 [239]

The acceleration of the ball is 5 m/s^2. This can be calculated using a formula that relates the change in velocity, acceleration, and time. This formula is:

Vf = Vi + at

where:
Vf = final velocity
Vi = initial velocity
a = acceleration
t = time

Substituting the values gives:

30 = 20 + a(2)
a = 5 m/s^2 --> Final Answer
