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.
What is Physical weathering?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.

What type of cells provide humoral immunity ?
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.

1. If a rock is dropped from a 600 meter cliff, how long will it take to hit the ground?
Dl
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

If it is 9 am in San Francisco, is it also 9 am in New York? Why or why not?
If it is 9 am in San Francisco, then there will be 12pm in New York. it happens because of spin rotation of our earth.
What is Clock ?A clock or a timepiece is a device used to measure time. The clock is one of the oldest human inventions. It has three hands moves in the circle. one is second hand, which show seconds. Second hand shows hours and third hand which is smaller than other shows hours.
San Francisco, California is 3 hours behind New York. There will be 12pm in New York when it is 9 am in San Francisco. Day and night happens because of our earth is spinning about itself. when we take a football in the dark room and illuminated it by the torch, then one side of the ball gets illuminated and other side of the ball gets dark due to shadow of its own, Same happens with our earth. it this case torch is our sun and earth is our football. The people who are on the darker side they are in the night and who are in the light side they are in the morning.
Morning starts where edge of the light is. Tme changes with lateral distance on the earth. The points which is on same longitude have same time. There is lateral displacement from San Francisco to New York. Therefore there is time lag between them.
Hence there is time lag.

The athlet at point A runs 150m east, then 70m west and then 100 east
Determine the resultant displacement of the athlete relative to point A
Answer:
180m to the east
Explanation:
Displacement is the distance traveled in a specific direction. It is a vector quantity with both magnitude and direction. Therefore, the start and finish position is very paramount.
point A runs 150m east,
70m west
100m east
150m

70m
←---------------------
100m

The displacement of the athlete = 150 - 80 + 100 = 180m to the east
when talking about Acceleration ,what is significant about the about the sign(+ or -)?
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.

A 2.00 kg ball is thrown upward at some unknown angle from the top of a 20.0 m high building. If the initial magnitude of the velocity of the ball is 20.0 m/s. What is the magnitude of the
FINAL VELOCITY when it strikes the ground? (Note: Ignore air resistance.)
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.
What is kinetic energy?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.

A ball rolls with a speed of 3 m/s across a level table that is 1.5m above the floor. How far along the floor is the landing spot from the table?
Answer:
d = 1.65 m
Explanation:
Given that,
The speed of a ball, v = 3 m/s
A ball rolls a level table that is 1.5 m above the floor.
We can find how long the ball is in free fall. We can use the second equation of kinematics as follows :
[tex]s=ut+\dfrac{1}{2}gt^2[/tex]
u is the initial speed in the vertical direction
So,
[tex]s=\dfrac{1}{2}gt^2\\\\t=\sqrt{\dfrac{2s}{g}} \\\\t=\sqrt{\dfrac{2\times 1.5}{9.8}} \\\\t=0.55\ s[/tex]
Now, using the formula of velocity.
[tex]v=\dfrac{d}{t}\\\\d=vt\\\\d=3\times 0.55\\\\d=1.65\ m[/tex]
So, the landing spot is at 1.65 m from the table.

These snakes can sense electromagnetic waves that have a lower frequency and a longer wavelength.
How do snakes detect?With almost ineffective hearing and vision, snakes can be extremely fast animals. Snakes can use chemoreceptors, heat, and even their tails to recognize prey and mates. With mostly ineffective hearing and vision systems, snakes can be extremely fast animals.
They also “see” in infrared. Thanks to the mechanism, they can track prey up to a meter away by the heat of their bodies. They use a simple organ, the loreal pit, located near the nostrils.

How does the sun maintain its high temperature and energy output?
Answer:
The core of the sun is the region that extends from the center to about 20–25% of the solar radius. It is here, in the core, where energy is produced by hydrogen atoms (H) being converted into nuclei of helium (He). ... The core is the only part of the sun that produces an appreciable amount of heat through fusion.
Explanation:
I got you
By not running out of fuel (Hydrogen).
Rest assured ... When the sun runs low on Hydrogen, it'll go through several complex changes, and it'll end up at much much lower temperature, with much much lower energy output.
Which situations will NOT increase the reactions rate of most chemical reactions?
A) an increase in temperature
B) grind up the solute to increase surface area before mixing
C) by increasing the pressure in which the reaction takes place
D) decreasing the concentrations of the substances in the reaction
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.
What is 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.
