Answer:

B) The average speed of the car increases as distance traveled increases.

Explanation:

The unbalanced forces acting on the toy car affect its average speed, The average speed of the car increases as distance traveled increases. Therefore, option A is correct.

The term average speed is defined as the total distance traveled by the object in a particular time interval. The average speed is a scalar quantity. It is corresponded to the magnitude and does not have direction.

Average speed is calculated by dividing the total distance something travels by the total amount of time it spends traveling.

Average speed = Total distance covered / Total Time. The S.I. unit of speed is meter per second.

The unbalanced forces acting on the toy car impact its average speed, The average speed of the car increases as distance traveled increases.

Thus, option A is correct.

Answer:

No

Explanation:

Acceleration refers to the increase in speed over time. Since both of the objects are moving at a constant speed (so the speed is not changing) neither are accelerating, because acceleration requires a positive change in speed.

They may be moving at different speeds, one faster than the other, but neither are changing their own speed so neither are accelerating.

Answer:

The liquid state of matter is an intermediate phase between solid and gas. ... Liquids will flow and fill the lowest portion of a container, taking on the shape of the container but not changing in volume. The limited amount of space between particles means that liquids have only very limited compressibility

Explanation:

A liquid is a nearly incompressible fluid with a nearly constant volume regardless of pressure that adapts to the shape of its container. It belongs to one of the four basic states of matter.

Volume retention and conformity to the shape of a liquid's container are two of its most noticeable physical characteristics. When a liquid substance is poured into a container, it conforms to the shape of the container and will stay inside the container so long as the liquid state persists.

The intermolecular forces of attraction in a liquid state of matter are stronger than those in a gaseous state but weaker than those in a solid state.

The ratio of an object's mass to its volume is called density of an object

Explanation:

Density=mass/volume

Answer:

I believe the answer is A

Explanation:

Explanation:

density = mass/volume so volume = mass/density = 40/4.30

Answer:

No.

Explanation:

No, convection does not occur if Earth's mantle were a box 30 km on a side because convection needs medium for the movement of heat energy from one place to another. Convection and conduction are two processes which needs medium for its movement while radiation does not need any medium for its movement. If there is a empty space present between two substances so convection does not occur.

Answer:

an apple is best described as a heterogeneous mixture.

The phrase that best describes an apple is heterogenous mixture because it is made up of a different materials.

A mixture is combination of different components that can be uniform or dispersed and homogenous or heterogenous.  A homogenous mixture is the one in which the two or more components are dissolved together to form only one phase.

A heterogenous mixture is composed different phases with uniform or irregular arrangement of materials. Heterogenous mixtures look like a nonseparated random particles which are clearly distinguishable by eyes.

Apple is not a compound but is a mixture made up of different components such as water, pulp, seeds, pigments etc. and each forms their own phases.

Hence, Apple can be termed as a heterogenous mixture.

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

Given:

The reaction:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

To find:

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide.

Solution:

[tex]2Ca+O_2\rightarrow CaO[/tex]

Mass of calcium = 10 g

Moles of calcium = [tex]\frac{10 g}{40.078 g/mol}=0.25 mol[/tex]

According to reaction, 2 moles of calcium reacts with oxygen, then 0.25 moles of calcium will react with:

[tex]=\frac{1}{2}\times 0.25 mol=0.125 \text{ mol of }O_2[/tex]

Mass of 0.125 moles of oxygen gas:

[tex]0.125 mol\times 31.998 g/mol=3.99975 g\approx 4.0 g[/tex]

The mass of oxygen needed to react 10 grams of calcium to form calcium oxide is 4.0 grams.

In the case when the bottle should be thrown into the fire so here Charles' Law should be applied.

Charles's law is a statement where the volume should be occupied by a fixed amount of gas that should be directly proportional to its absolute temperature in the case when the pressure remains constant.

Carbon dioxide is a compound because it contain more than one type of elements, carbon and oxygen, which are chemically bonded.

Answer:

The substance has a density of 2.636 grams per mililiter.

Explanation:

We must remember that density ([tex]\rho[/tex]), measured in grams per mililiters, is the mass of the substance ([tex]m[/tex]), measured in grams, divided by its volume ([tex]V[/tex]), measured in mililiters. That is:

[tex]\rho = \frac{m}{V}[/tex]

In addition, a kilogram equals 1000 grams and a liter equals 1000 mililiters. If we know that [tex]m = 1713.2\,g[/tex] and [tex]V = 650\,mL[/tex], then:

[tex]\rho = \frac{1713.2\,g}{650\,mL}[/tex]

[tex]\rho = 2.636\,\frac{g}{mL}[/tex]

The substance has a density of 2.636 grams per mililiter.
