Daniel needed 5.0 x 10 3mm of copper wire for his senior year science project. When Daniel went to the hardware store, he noticed that the unit of measure used for the wire was meters. Calculate the length, in meters, of copper wire Daniel needed for his project.

Answers

Answer 1

Answer:

if its 5X 10^3 mm=5m and if its 5X 10^-3 mm=5X 10^-6m

Explanation:

we know,

1m= 1000mm

as given 5X 10^3 mm we have to convert to meter

now  5X 10^3 mm= 5X 10^3/1000=5m

but if its  5X 10^-3 mm= 5X 10^-3/1000= 5X 10^-6m

What are the units for Rf values? Please help!

Answers

Answer:

Microwatts.

Explanation:

RF + EMF Unit Conversion Charts: Interpreting exposure levels. When measuring Radio Frequencies, the most common units of measurement are microwatts per square meter (µW/m2), microwatts per square centimeter (µW/cm2) and volts per meter (V/m).

Answer:

No units

Explanation:

In Thin Layer Chromatography (TLC), retention factor (Rf value) is found by taking the distance travelled by the spot divided by the distance of the solvent front. Rf value is a ratio of distances hence they have no units.

Mathematical derivation

The distance travelled by the spot is in cm, and that of the solvent front is also in cm. Thus, dividing the two units would give us no units for the Rf value.

What is TLC?

TLC is a technique used for separation and identification. The stationary phase is polar while the solvent is relatively nonpolar. Thus, the less polar substance is more attracted to the solvent (according to the principle of 'like attracts like') and travels further and thus have a higher Rf value.

A.) dwarf
B.) supernova
C.) black hole
D.) giant

Answers

B is the correct answer

As a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.

What is a Star?

A star may be defined as a type of huge celestial body that is generally constructed of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. They are the luminous bodies that are visible in the sky at night.

A giant is a type of star that has utilized its hydrogen supply in its cores and transformed itself into the thermonuclear fusion of hydrogen in the shell that envelops its surroundings.

This creates an outwards force and stimulates fusion that initiates to increase and hence the star can not able to maintain its equilibrium longer.

Therefore, as a star uses up its hydrogen supply, it changes from the main sequence star to a Giant. Thus, the correct option for this question is D.

how many grams in 5mg

Answers

Answer:

0.005

Explanation:

I looked it up

Explanation: It's important to understand that "mg" is the abbreviation

for milligrams and "g" is the abbreviation for grams.

To convert 5 milligrams into grams, we first find the conversion factor

for milligrams and grams, which is 1,000 milligrams = 1 gram.

Next, notice that we're going from a smaller unit,

milligrams, to a larger unit, grams, so we divide.

Whenever we go from a smaller unit to a larger unit,

we will divide by the conversion factor.

So we have 5 mg ÷ 1,000.

When dividing by a power of 10, we can count the number of zeroes

in the power of 10 and move the decimal point that many places to the left.

So our answer is 0.005 grams.

5. If a block of wood has a density of 0.6 g/cm3 and a mass of 120 g, what is its volume? (D= M/V)

Answers

Answer:

200 cm^3

Explanation:

V = M/D

V = 120g / (0.6g/cm^3)

V = 200 cm^3

In this case, the volume is 200 cm^3.

What is density?

Density is defined as the mass of a material substance per unit volume. The equation for density is d = M/V, where d stands for density, M for mass, and V for volume. Grams per cubic centimetre are a typical unit of density measurement.

For instance, the density of Earth is 5.51 grammes per cubic centimetre, but the density of water is 1 gramme per cubic centimetre. Kg/m3 is another way to measure density (in metre-kilogram-second or SI units). For instance, the air has a density of 1.2 kilogrammes per cubic metre.

Textbooks and manuals provide lists of the densities of common solids, liquids, and gases. The mass of a body may be calculated from its volume using density, and vice versa. The mass is equal to the volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).

You may calculate a body's weight by multiplying its mass by the acceleration of gravity, which is typical of more practical significance than its mass. Additionally, there exist tables that indicate the weight of various substances per unit volume; this amount is sometimes referred to as specific weight, weight density, or unit weight.

Instead of referring to the density of a single particle, the term "particle density" refers to the number of particles per unit volume and is typically written as n.

Therefore, here the volume is 200 cm^3.

which best represents a particle containing 28 protons, 26 electrons,and 34 neutrons?

Answers

Answer:

This question lacks options, but the question can be answered based on knowledge of proton, electron and neutron number. The answer is:

62 Ni2+ particle

Explanation:

Nickel is a chemical element with atomic number 28. This means it has 28 electrons and 28 protons in its neutral atom. However, the isotope of nickel being described in the question has a mass number of 62. The mass number is calculated by adding the proton number with the neutron number. That is;

Mass number = number of protons + number of neutrons

Mass number = 28 + 34

Mass no. = 62

An element with mass number 62, which has lost two electrons to become positively charged (two positive charges) is described in the question. Hence, the particle that best fits this description is positively charged Nickel particle (Ni2+).

Ni2+ has 28 protons, 26 electrons (reduced by 2) and 34 electrons.

Note that, the 2+ charge is as a result of the loss of two electrons, hence, reducing the electron number by 2.
