Tokyo, Japan is 8817.6 km from California. how many millimeters is this? answer in scientific notation.​

Answers

Answer 1

Answer:

[tex]d=8.817\times 10^9\ mm[/tex]

Explanation:

It is given that,

Japan is 8817.6 km from California. We need to convert this distance in millimeters.

We know the conversion from km to mm is as follows :

1 km = 1000000

To convert mm km to mm use the unitary method as follows :

8817.6 km = 8817.6 × 1000000

[tex]d=8.817\times 10^9\ mm[/tex]

Hence, the distance between Japan and California [tex]8.817\times 10^9\ mm[/tex].

13. A sample of copper has a volume of 14.75 cm3. The density of copper is 8.96 g/cm3. What is the mass of this sample?

Answers

Answer:

The answer is

132.16 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

volume of copper = 14.75 cm³

Density = 8.96 g/cm³

The mass is

mass = 8.96 × 14.75

We have the final answer as

132.16 g

A mixture is made by combining 1.17 lb of salt and 3.54lb of water.What is the percentage of salt (by mass) in this mixture?

Answers

Answer:

The percentage of salt in the mixture 24.84%

Explanation:

In this problem we are required to solve for the percentage of salt in the mixture of salt and water

Step one :

We can proceed by first solving for the total mass of the mixture

Which is given as

mass of mixture =mass of salt +mass of water

Mass of mixture = 1.17+3.54

Mass of mixture = 4.71 lb

Step two :

Now let us calculate the percentage of salt present in the mixture which is

=(mass of salt/mass of mixture) *100

=(1.17/4.71)*100

=0.248*100

=24.84%

The weight of a cup with water is 2.58 kg the weight of the empty cup is 1.5 kg considering significant figures what is weight of the water

Answers

Answer:

The correct answer is 1.1 kg

Explanation:

From the data provided:

Weight (cup + water)= 2.58 kg

Weght (cup) = 1.50 kg

Thus, we simply calculate the difference between the full cup and the empty cup to obtain the net weight of water:

Weight (water) = Weight (cup + water) - Weght (cup)

                         = 2.58 kg - 1.50 kg

                         = 1.08 kg ≅ 1.1 kg

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?

Answers

Answer:

Boiling point: physical

Density: physical

Ductility: physical

Heat of combustion: chemical

Explanation:

Chemical properties can only be analyzed by putting the substance through a chemical reaction, such as combustion.

Physical properties can be analyzed without altering the substance chemically. With that in mind:

Boiling point is the physical property, density is the physical property, ductility is also a physical property but combustion of heat is a chemical property.

What is physical and chemical property?

A physical property is the characteristic of a substance or compound that is observed without any change in the identity of the particular substance.

The physical properties of a substance is its colour, hardness, density, and melting as well as boiling points.

A physical property is a characteristic of matter that involves in physical change and physical changes are reversible and there is no production of any new substance.

The chemical change is the property of a substance due to which new substances are formed and it is non reversible change.

The chemical properties are flammability, toxicity, heat of combustion, coordination number, enthalpy of formation, and oxidation states.

Therefore, Boiling point is the physical property, density is the physical property, ductility is also a physical property but combustion of heat is a chemical property.

Acceleration can be defined as  the vector quantity  and has both magnitude and direction, it is a second derivative of position with respect to time  and it is the first derivative of velocity with respect to time.

The change in the velocity of an object called as acceleration and the Velocity is a vector quantity with both magnitude and direction.

Acceleration can be a change in the direction of an object. For example, while pressing the accelerator of car makes the car go faster.
