In Florida, most of the rocks that are underground are a type of soft, white rock called limestone. Long-term submergence in water causes limestone to disintegrate. These processes most likely causes this change is called Physical weathering. Hence, Option D is the correct answer.

Physical weathering is also known as mechanical weathering. It is the weakening of rocks followed by the disintegration due to the physical or mechanical forces including the actions on the rocks by the abrasion, frost chattering, temperature fluctuations and the salt crystal growth. Eventually, after many cooling and heating events, the rocks cracks and break into smaller pieces.

This same mechanical process applies when water freezes and thaws in the cracks of a rock.  The chemical composition of the rock, however, remains the same in the process. In Florida, most of the rocks that are underground are a type of soft, white rock called limestone. Long-term submergence in water causes limestone to disintegrate.

These processes most likely causes this change is called Physical weathering. Hence, Option D is the correct answer.

Answer:

11.1s

Explanation:

Given parameters:

Height of cliff  = 600m

Unknown:

How long it takes to hit the ground  = ?

Solution:

To solve this problem, we use one of the kinematics equation;

    H  = ut  +  [tex]\frac{1}{2}[/tex]gt²  

H is the height

u is the initial velocity  = 0m/s

t is the time taken

g is the acceleration due to gravity

             600 = [tex]\frac{1}{2}[/tex] x 9.8 x t²  

              600  = 4.9t²  

                 t²  = 122.5

                 t  = 11.1s

Answer:

Antibody molecules that are secreted by plasma cells mediate the humoral immune response. The antigen that binds to the receptor of the B-cell antigen signals B cells and is internalized and transformed into peptides that activate the armed helper at the same time.

Explanation:

Answer:

B cells

Explanation:

Humoral immunity or humoural immunity is the aspect of immunity that is mediated by macromolecules found in extracellular fluids such as secreted antibodies, complement proteins, and certain antimicrobial peptides. Humoral immunity is named so because it involves substances found in the humors, or body fluids. It contrasts with cell-mediated immunity. Humoral immunity is also referred to as antibody-mediated immunity.

Answer:

0kgm/s

Explanation:

The momentum of the empty car is zero.

Momentum is the quantity of motion a body possess. The more the mass and velocity by which a body moves, the higher is its momentum.

 Momentum  = mass x velocity

Since the second car is at rest, the velocity is 0m/s;

 So;

     Momentum  = 100 x 0 = 0kgm/s

Therefore, a body at rest has zero momentum

Solution:

Density is the mass per unit volume of a substance.

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

Explanation:

Given parameters:

Force applied on the car  = 1000N

Distance moved  = 75m

Unknown:

Work done  = ?

Solution:

The work done by a body is the force applied to move it through a particular distance.

So;

    Work done  = Force x distance

Therefore;

    Work done  = 1000 x 75  = 75000J

Answer:

W = 15,000 Joule

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

If both the force and displacement are parallel, then we can use the scalar formula:

W=F.s

Where

F =Magnitude of the force

s = magnitude of the displacement

The tornado moved a trailer with a force of F=600 N for a distance of s=25 m. The work done was:

W = 600 N * 25 m

W = 15,000 Joule

Answer:

Ro = 1000 [kg/m³]

Explanation:

We must remember that density is defined as the relationship between mass and volume.

[tex]Ro=m/V\\[/tex]

where:

Ro = density [kg/m³]

m = mass = 3 [kg]

V = volume = 3000 [ml]

We must convert the volume of milliliters to cubic meters

[tex]3000[ml]*\frac{0.001Lt}{1ml}*\frac{1m^{3} }{1000Lt} = 0.003m^{3}[/tex]

Now replacing:

[tex]Ro=3/0.003\\Ro=1000[kg/m^{3} ][/tex]

Answer:

a.200 Newtons

Explanation:

Given the following data;

Mass = 20kg

Acceleration = 10m/s²

To find the force;

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex]

Where;

F represents force.

m represents the mass of an object.

a represents acceleration.

Substituting into the equation, we have

[tex] Force = 20 * 10 [/tex]

Force = 200 Newton.

Answer:

h = 3.3 m (Look at the explanation below, please)

Explanation:

This question has to do with kinetic and potential energy. At the beginning (time of launch), there is no potential energy- we assume it starts from the ground. There, is, however, kinetic energy

Kinetic energy = [tex]\frac{1}{2}[/tex]m[tex]v^{2}[/tex]

Plug in the numbers = [tex]\frac{1}{2}[/tex](4.0)([tex]8^{2}[/tex])

Solve = 2(64) = 128 J

Now, since we know that the mechanical energy of a system always remains constant in the absence of outside forces (there is no outside force here), we can deduce that the kinetic energy at the bottom is equal to the potential energy at the top. Look at the diagram I have attached.

Potential energy = mgh = (4.0)(9.8)(h) = 39.2(h)

Kinetic energy = Potential Energy

128 J = 39.2h

h = 3.26 m

h= 3.3 m (because of significant figures)

Answer:

D

Explanation:

Increasing temperature or pressure some times make the condition favorable to the reaction. Similarly increasing surface area  of reacting mixture also helps to increase the reaction rate.

The rate of  a reaction is the rate of decrease in concentration of reactant or the rate of increase in concentration of the products. The rate of a reaction depends on several factors such as temperature, pressure, surface area etc.

Fir an endothermic reaction, as the temperature increases, reaction rate increases. Similarly, as the pressure increases, the reaction in which the number of moles of gaseous reactants is higher than that in products, rate increases.

The concentration of reactants must be sufficient for the reaction and decreasing the concentration of reactants does not favor an increase in reaction rate. Hence, option D is correct.

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:

Acceleration at its most basic is the act of increasing your running speed. From a standing start (or blocks), you explode into action. If you’re already running, you pick up the pace. Acceleration continues until you can no longer increase your speed, at which point you achieve maximum velocity (top-end speed). Acceleration seems simple enough. The plus means your increasing speed, the k=minus means your decreasing in speed.
