Answer:

True

Explanation:

A mnemonic device is a method employed to make the memory have the ability to remember things, improve the memory, and generally improve the long term ability of the memory such that the brain develops more ability to store information until when needed and collect the stored information when needed. This is achievable when the information that needed to be remembered are stored using rhymes of songs, abbreviations of words using the initial letters. For example, "MR NIGER D" can be used to store the characteristics of living things like:

M - movement

R - Respiration

N - Nutrition

I - Irritability

G - Growth

E - Excretion

R - Reproduction

D - Death

The radius of an atom of krypton (kr) is about 1.9 å. (a) express this distance in nanometers (nm). nm express this distance in
I am Lyosha [343]
Note:
1 A (armstrong) = 10⁻¹⁰ m
1 nm (nanometer) = 10⁻⁹ m

Given:
Radius of a krypton atom = 1.9 A = 1.9 x 10⁻¹⁰ m

Part (a)
1.9\,A = (1.9\,A)*(10^{-10}\, \frac{m}{A})*( \frac{1}{10^{-8}} \frac{nm}{m}) } =0.019\,nm
Answer: 0.019 nm

Part (b)
The diameter of a krypton atom = 2*1.9A = 3.8 A = 3.8 x 10⁻¹⁰ m.
The number of krypton atoms within a length of 1.0 mm is
\frac{1.0\, mm}{3.8 \time 10^{-10}\, m} = \frac{10^{-3}\, m}{3.8 \times 10^{-10} \,m} =2.632 \times 10^{6}

Answer: About 2.632 x 10⁶ atoms

Part (c)
The radius of a krypton atom is
1.9 A = (1.9 x 10⁻¹⁰ m)*(10² cm/m) = 1.9 x 10⁻⁸ cm
The volume of a krypton atm is
\frac{4 \pi }{3} (1.9 \times 10^{-8} \, cm)^{3} = 2.873 \times 10^{-23} \, cm^{3}

Answer: 2.873 x 10⁻²³ cm³

An object has a mass of 8.00 kg. what is the gravitational force of the object on earth
KonstantinChe [14]

When a mass of 8 kg is located on the Earth's surface, the magnitude of each of
the gravitational forces attracting the mass and the Earth toward each other is

       (mass) x (acceleration of gravity on Earth) =

      (8.0 kg) x (9.81 m/s²) =

                78.48 kg-m/s²  =  <em>78.48 newtons  </em>(about 17 pounds 10.2 ounces)

What do the symbols mean???
Elena L [17]

1. Fixed resistor ; A resistor is used to reduce the flow of electricity in an electric circuit. Resistors come in fixed or variable types. A fixed resistor cannot be changed as it is set at a specific value, whereas a variable resistor can manage flows at and below a specific level.

2. Variable Resistor ;

An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of carbon or a resistive wire made of nickel chromium or tungsten alloys.

3. Thermistor ;

Converts heat to electrical resistance.

4. Light dependant resistor ;

Converts light to electrical resistance.
