Answer:

When matter changes from one state to another, it either absorbs energy—as when chocolate melts—or loses energy. For example, if you were to place the melted chocolate in a refrigerator, it would lose energy to the cold air inside the refrigerator. As a result, the liquid chocolate would change to a solid again.

c is the correct answer ......... if we cut a magnet i will divide into two halves and ecah half have a southpole and northpole.

Hope it helps

When a bar magnet is cut in half, each half has both a north pole and a south pole. Therefore, option C is correct.

This phenomenon is due to the rearrangement of magnetic domains within the material. The newly formed magnets will have a north pole on one end and a south pole on the other end. This process can be repeated, resulting in smaller and smaller magnets, but each piece will always exhibit both north and south poles.

The magnetic properties are retained even when the magnet is divided into smaller segments. Each half of the magnet becomes a new magnet with its own north and south pole.

Answer: A scalar quantity has magnitude but no particular direction and a vector quantity has magnitude and acts in a particular direction.

Explanation:

Answer:

yes

Explanation: if temperature is higher the reactants have more kinetic energy make the chemical reaction faster

Answer:

increasing the temperature will cause chemical changes to occur faster

Decreasing the temperature, causes the particle to lose energy which causes them to move around less and slower

Explanation:

chemical changes

>produce new substances w/ different chemical structure/ properties

> thermal energy can be used to BREAK bonds (endothermic)

>thermal energy can be transferred to a chem rxn to help form new products (endothermic)

> heat can be released by an exothermic chemical reaction (excess energy- the total energy used to break bonds is less than energy released in forming new bonds)

physical changes

>does not result in new substances (typically changes in state- solid, liquid, gas)

> thermal energy can be transferred to EVAPORATE water (add thermal E... water (liquid) to steam (gas)) or FREEZE water (remove thermal E... water (liquid) to ice (solid))

Answer:

A person or object may have stored energy because of its....

potential energy

A person or object may have stored energy because of its position and the energy is called potential energy.

The relative positions of different system components determine the potential energy, which is stored energy. When a spring is compressed or stretched, its potential energy increases.

If a steel ball is raised above the ground as opposed to falling to the ground, it has more potential energy. It is capable of performing more work when raised.

Potential energy is a characteristic of systems rather than of particular bodies or particles; for instance, the system made up of Earth and the elevated ball has more potential energy as they become further apart.

In systems having components whose forces on one another rely on their configuration, or relative positions to one another, potential energy is generated.

Given:

Momentum of the dog (p) = 120.5 kg m/s

Speed of the dog (v) = 5 m/s

To Find:

Mass of the dog (m)

Concept/Theory:

[tex] \underline{\underline{ \bf{\Large{Momentum}}}}[/tex]

Answer:

By using equation of momentum, we get:

[tex] \rm \longrightarrow m = \dfrac{p}{v} \\ \\ \rm \longrightarrow m = \dfrac{120.5}{5} \\ \\ \rm \longrightarrow m = 24.1 \: kg[/tex]

[tex] \therefore [/tex] Mass of the dog (m) = 24.1 kg

Answer:

The final speed of the second bicycle is (v·√2)/2

Explanation:

The mass of the given bicycle = m

The amount of work required to move the bicycle from rest to speed v = 50 J

The final speed of the first bicycle = v

The mass of the second bicycle = 2m

Therefore, from conservation of energy, we have;

Work required by the first bicycle = Kinetic energy gained by the bicycle

The kinetic energy = 1/2·m·v²

∴ Energy required by the first bicycle = 50 J = 1/2·m·v²

Given that the same amount of work is performed on the second bicycle, we have;

Work performed on the second bicycle = 50 J = kinetic energy of second bicycle = 1/2·(2·m)·v₂²

Also, given that 50 J = 1/2·m·v², we have;

Work performed on the second bicycle = 50 J = 1/2·m·v²= 1/2·(2·m)·v₂²

1/2·m·v²= 1/2·(2·m)·v₂²

m·v² = 2·m·v₂²

v² = 2·v₂²

v₂ = √(v²/2) = v/√2 = (v·√2)/2

v₂ = (v·√2)/2

The final speed of the second bicycle = v₂ = (v·√2)/2.

Answer:

127.6 m

Explanation:

Given that  Zane has an elastic water balloon launcher that can fire balloons at an angle of [38.0o] from the surface of the ground. If the initial velocity is 25.0 m/s,

The horizontal initial velocity will be:

U = 25cos38

U = 19.7 m/s

To find how far away are the balloons are from the launcher when they hit the level ground again, we will first calculate the total time spent before using the range formula

To calculate the total time, let's use the formula below:

T = 2U/g

T = (2 × 25)/9.8

T = 50/9.8

T = 5.1s

Range = UT

Since horizontal acceleration = 0

Range = 25 × 5.1

Range = 127.55 m

Therefore, the balloons are approximately 127.6m away from the launcher when they hit the level ground again
