Explanation:

Answer:

They remain the same

Explanation:

As the molecule goes from reactants to products, the number of atoms in the each of the element remains the same.

This is in compliance with law of conservation of matter. The law proposes that "in a chemical reaction, matter is neither created nor destroyed by changed from one form to another".

So, since no matter is destroyed, the number of atoms during a chemical change remains the same before and after a reaction.

This is applicable to all chemical changes.

Answer:

0.2g/cm³  

Explanation:

Given parameters:

Mass of the beef  = 11.6g

Volume  = 58cm³  

Unknown:

Density  = ?

Solution:

Density is the mass per unit volume of a substance.

  Density  = [tex]\frac{mass}{volume}[/tex]  

So;

  Density  = [tex]\frac{11.6}{58}[/tex]    = 0.2g/cm³

Answer: 28.1

Explanation:

The total energy of the ball is the sum of its kinetic and potential energy. It is equal to 792 J. Then, the final velocity of ball when its strikes the ground is 28.1 m/s.

Kinetic energy of an object is the energy gained by its motion whereas, potential energy is stored on the object when the object is at rest.

The total mechanical energy of the ball = Ke + Pe

given, mass of the ball = 2 Kg

height h= 20 m

initial velocity = 20 m/s

Then total energy = 1/2 mv² + mgh =  2 kg  [(1/2(20 m/s)² + 9.8 m/s² ×20 m ] = 792 J.

The final velocity Vf = √(2E/m) =√(2×792 J/m)/2 Kg = 28.1 m/s

Therefore, the final velocity of the ball will be 28.1 m/s.

Answer:

I. A radio transforms electrical energy into sound energy = audio sound.

II. A bulb converts electrical energy into heat and light energy = light.

III. A standing fan converts electrical energy into kinetic energy.

IV. The sun converts nuclear energy into light and heat energy.

V. A microwave oven converts wave energy into heat energy.

Explanation:

Energy can be defined as the ability of a body to do work. There are different forms of energy and these includes; electrical energy, sound energy, light energy, wave energy, nuclear energy, solar energy, etc.

According to the law of conservation of energy which states that, energy cannot be destroyed but can only be converted or transformed from one form to another.

Hence, some examples of energy being converted or transformed are;

I. A radio transforms electrical energy into sound energy = audio sound.

II. A bulb converts electrical energy into heat and light energy = light.

III. A standing fan converts electrical energy into kinetic energy.

IV. The sun converts nuclear energy into light and heat energy.

Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we'll refer to as simply "heat capacity", meaning it takes more energy to increase the temperature of water compared to other substances.

Answer:

- 0.25m/s²

Explanation:

Given parameters:

Initial velocity  = 40m/s

Final velocity  = 30m/s

Time taken  = 40s

Unknown:

Acceleration of the car  = ?

Solution:

Acceleration is the rate of change of velocity with time.

 So;

  Acceleration  = [tex]\frac{Final velocity - Initial velocity }{time }[/tex]  

 Acceleration  = [tex]\frac{30 - 40}{40}[/tex]    =  - 0.25m/s²

This implies that the car will decelerate at a rate of 0.25m/s²

Answer:

Explanation:

The heat of the solar radiation is absorbed by the atmosphere then the atmosphere re-releases heat, warming Earth’s surface and lower atmosphere. Therefore, option (3), (4) are correct.

The greenhouse effect can be described as a process that happens when energy heats the planet's surface, but greenhouse gases in the atmosphere stop some of the heat from returning directly to space and warm the planet.

The natural greenhouse effect keeps the earth from having the below-freezing temperature that it would freeze if there were no greenhouse gases. Additionally, human activities increase greenhouse gases and trap greater amounts of heat, which cause the Earth to grow warmer over time.

The Sun sends most of its energy as visible and near-infrared light, while Earth's average surface temperature emits longer-wavelength infrared, radiant heat. These greenhouse gases emit radiant heat in all directions, passing heat to the air and warming other greenhouse gases.

Answer:

The three main rock types are igneous, metamorphic and sedimentary.

The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.

Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.

No

ALL rocks are connected in a cycle of creation, change, and destruction which is known as what is referred to as the rock cycle.

The rock cycle begins with molten rock, i.e, the magma below ground and the lava above ground, which cools and hardens to form igneous rock. These sediments can then be buried and hardened forming sedimentary rock.

A rock is a solid mass of geological materials. They are naturally formed, non-living earth material. Rocks are made of collections of mineral grains that are held together in a firm solid mass

Answer:

a. Yes, because the acceleration of the crate is 2.0 m/s².

Explanation:

Given

[tex]Force = 6N[/tex] --- f

[tex]Mass = 3kg[/tex] --- m

[tex]Time = 1.5s[/tex] --- t

[tex]Velocity = 3.0m/s[/tex] --- v

Required

Does the system support [tex]F=ma[/tex]

Yes, it does and this is shown below

The crate is initially at rest; so:

[tex]u = 0[/tex]

Using the first equation of motion

[tex]v = u + at[/tex]

Substitute values for v, u and t

[tex]3 = 0 + a*1.5[/tex]

[tex]3 = 1.5a[/tex]

Make a the subject

[tex]a = 3/1.5[/tex]

[tex]a = 2[/tex]

Using [tex]F = ma[/tex]

Substitute values for F and m

[tex]6 = 3 * a[/tex]

Divide both sides by 3

[tex]6/3 = 3/3 * a[/tex]

[tex]2 = a[/tex]

[tex]a = 2[/tex]

In both cases:

[tex]a = 2[/tex]
