how do you do this? do you multiply the two together, and in that case how do you get the finishing unit?

Answer:

Their answers must be in two decimal places

All of them should view the scale from the front to avoid parallax error and the scale should be kept corresponding to the end of the pencil to accurately measure its length.

Because your eye is angled toward the measuring marks, parallax error happens when the length of an object is measured as being longer or shorter than it actually is. For instance, someone looking at a car's speedometer from the driver's seat will see it clearly and receive an accurate reading.

Due to the angle formed by his eye, the speedometer, and the arrow, a person observing the speedometer from the passenger seat will overestimate the reading.

On a ruler or other similar instrument, position your line of sight such that it is immediately above the measurement marking, creating an imagined vertical line between your eye, the marking, and the item. The main reason for parallax error is when you see an item in relation to the scale from an angle that causes it to appear to be at a different location on the scale.

Therefore, they should view the scale from the front to avoid parallax error and the scale should be kept corresponding to the end of the pencil to accurately measure its length.

Explanation:

that's what's it should be.

Answer:

1.18×10²³ atoms.

Explanation:

From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ atoms.

From the above concept, 1 mole of sodium also contains 6.02×10²³ atoms.

1 mole of sodium = 23 g.

Thus,

23 g of sodium contains 6.02×10²³ atoms.

Therefore, 4.5 g of sodium will contain = (4.5 × 6.02×10²³)/23 = 1.18×10²³ atoms.

From the above calculation,

4.5 g of sodium contains 1.18×10²³ atoms.

Explanation:

Answer:

1.12 g.

Explanation:

From the question given above, the following were obtained obtained:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

The density of a material is simply defined as the mass of the material per unit volume of the material. Mathematically, it is expressed as:

Density (D) = mass (m) / volume (V)

D = m/V

With the above formula, we can easily calculate the mass of the metal as shown below:

Volume (V) of metal = 2.3 cm³

Density (D) of metal = 0.486 g/cm³

Mass (m) of metal =..?

D = m/V

0.486 = m/2.3

Cross multiply

m = 0.486 × 2.3

m = 1.12 g

Therefore, the mass of the metal is 1.12 g.

Answer: a meter is a meter

Explanation:

a meter is a certain lenght. it does not change when you're somehwere else

A meter is the SI unit for length. This means that it is an international standard unit which is the same in America and France.

The International System of Units (SI) is a French system. It is called French Système International d’Unités. It is an international decimal system of weights and measures. It has been derived from the metric system and extended it further.

It was adopted by the 11th General Conference on Weights and Measures (CGPM) in the year 1960, it is abbreviated as SI in all languages.

In the 19th and 20th centuries, rapid advances took place in the field of science. These developments resulted in the development of several overlapping systems of units of measurement. These were improvised by scientists to meet the practical needs of their disciplines.

The earlier international system that was developed for solving this issue was called the meter-kilogram-second (MKS) system. Then there was the CGPM system which added three new units in 1948. It used a unit of force, the newton.

It is defined as the force that can be given to a mass of one kilogram to provide it with an acceleration of one meter per second per second. Also a unit of energy, the joule was defined. It is the work done when the application of a newton on a point is displaced by one meter in the direction of the force.

There was also a unit of power, the watt. This is the power that gives to the energy of one joule. All of these three units were named after eminent scientists.

Therefore, a meter is the same in America as well as France.

Answer:

A

Explanation:

Answer:

Explanation:

The formula for the force of gravity is

F=G * m1 * m2 / r^2

G is a constant. It does not change with the use of the formula.  There are 2 masses, so the force depends on the masses.

The right hand side is divided by r^2. that's a distance. So that's the other quantity influencing the Force.

B: incorrect. Both objects have masses. That determines the force between them.

C: incorrect. It's also the distance between them.

D: incorrect. The formula contains nothing to indicate that velocity is important.

The answer is A

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.

Explanation:

The groups in the periodic table that want to gain electrons are groups; 15, 16 and 17. The members of these groups are mostly nonmetals.

The periodic table is composed of 18 groups and 8 periods of elements. Groups 1 - 13 are metals while groups 15 -18 are nonmetals. Group 14 consists of a mixture of metals and nonmetals.

The nonmetals usually accept electrons while metals electrons easily donate electrons. Elements of group 18 neither receive nor donate electrons because they have a complete octet.

Nonmetals of groups 15 -17 gain electrons easily.
