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.

The equation for the formation of water from hydrogen gas and oxygen gas is 2H2+O2→2H2O . How many grams of water can be made from 64 g of oxygen gas?
Answer: 144 g
the mol of the oxygen gas is 64/16 = 4 (mol)
we have:
2H2 + O2 => 2H2O
4 ------> 8
=> the mol of H2O is 8 mol
=> m(H2O) = 8.(2 + 16) = 8.18 = 144 (g)
Explanation:
How far will a car travel in half an hour at
30 mph?
Answer:
The car will travel the distance of 15 miles
S= D/T
therefore
D=ST
D = Distance
S = Speed (30 mph)
T = Time (0.5 Hours)
D = 30 * 0.5 = 15

Given that renewable sources provide only a small percentage of our energy and that nuclear power is so expensive, in your opinion, what can we realistically do to get off fossil fuels as soon as possible?
Answer:
No getting rid of fossil fuel is not at all possible.
Explanation:
Dream of 100% renewable energy is possible through electrification and use of energy from sun, water and wind. Since, the high production cost of power plant for extracting energy from these sources in itself is a big challenge and hence decarbonized energy in current scenario is not realistic.
A projectile is fired at a velocity of 50 m/s straight into the air. What is the velocity of the projectile when the objects displacement is 16 meters and headed downward?
Answer:
the final velocity of the object is 53.04 m/s.
Explanation:
Given;
initial velocity of the projectile, u = 50 m/s
displacement of the object, d = 16 m
let the final velocity of the object = v
Apply the following kinematic equation to determine the final velocity of the projectile.
v² = u² + 2gd
v² = 50² + (2 x 9.8 x 16)
v² = 2813.6
v = √2813.6
v = 53.04 m/s
Therefore, the final velocity of the object is 53.04 m/s.

An object is experiencing an acceleration of 9.0 m/s? while traveling in a circle at a velocity of
6.2 m/s. What is the radius of its motion?
Answer:
4.27m
Explanation:
Recall that for uniform rotational motion,
the formula for centripetal acceleration is given as
Centripetal acceleration = ( velocity)² / radius
in our case we are given :
Centripetal acceleration = 9.0 m/s²
velocity = 6.2 m/s
substituting these into the formula:
9.0 = 6.2² / radius
radius = 6.2² / 9.0 = 4.27m
How far could you speed walk in 10 minutes? Use your speed from the 20m test to calculate the answer.
my speed is 13.63.
Answer:
Explanation:
Given parameters:
Time for speed walking = 10min
Speed = 13.63?
Unknown:
Distance you can speed walk = ?
Solution:
To solve this problem, we simply apply the velocity - time equation;
Speed = [tex]\frac{distance}{time}[/tex]
Distance = speed x time
make sure you speed and time are in the same unit
Insert the parameters and solve
Can a solution be separated by filtration?
Answer:
Filtration is a method for separating an insoluble solid from a liquid. When a mixture of sand and water is filtered: the sand stays behind in the filter paper (it becomes the residue ) the water passes through the filter paper (it becomes the filtrate )
Explanation:
Listo!
Can an object with acceleration of zero be in motion?
Answer:
NO
Explanation:
if it has no acceleration then it's not moving
Answer:
Yes when the velocity is constant then the acceleration is said to be zero. Thus an object with 0 acceleration can be in motion.
Let me give you an example to make you more clear
Example:
When a car is traveling at a constant 90 km/h in a straight line has nonzero velocity and zero acceleration.
In handball, who is the only player allowed in the goalie area?
Answer:
Only the goalie is allowed inside the goal crease. The only exception when another player is allowed in the goal area is when they take off from outside the goal area, and shoots or passes the ball before landing. To avoid interference with other players, the player must then exit the goal area as soon as possible.

A 3 kg object attached to a spring oscillates with an amplitude of 15 cm and a period of 2s. At a time t=0.5s, the object's position is x=9.1 cm.
Determine...
a) the spring constant of the spring.
b) the total energy of the system (in joules).
c) the maximum speed of the object.
d) the position of the object as a function of time. Use a cosine function.
Answer:
Follows are the solution to the given question:
Explanation:
For point a:
[tex]T= 2\pi \sqrt{\frac{m}{k}}\\\\k = \frac{4 \pi^2 m}{T^2}\\\\= \frac{4 \times (3.14)^2 \times 3}{2^2}\\\\=29.578 \ \frac{N}{m}\\\\[/tex]
For Point b:
[tex]E=\frac{1}{2} m a^2 w^2\\\\[/tex]
[tex]=\frac{1}{2} \times m \times a^2 \times \frac{4\pi^2}{T^2}\\\\=\frac{1}{2} \times 3 \times (0.15)^2 \times \frac{4\times 3.14^2}{2^2}\\\\=0.332 \ J[/tex]
For Point C:
[tex]V_{max}= a w[/tex]
[tex]= (0.15) \times \frac{2\pi}{T}\\\\= (0.15) \times \frac{2\times 3.14}{2}\\\\=0.471 \frac{m}{s}[/tex]
For point D:
[tex]X= a \sin (wt+ \phi)\\\\0.91=0.15 \sin(\frac{2\pi}{T} \times t+\phi)\\\\0.91=0.15 \sin(\frac{2\times 3.14}{2} \times 0.5+\phi)\\\\0.60 = \sin(3.14 \times 0.5+\phi)\\\\0.60 = \sin(1.57+\phi)\\\\1.57 +\phi =\sin^{-1} 60^{\circ}\\\\1.57 +\phi = 36.86^{\circ}\\\\=35.29^{\circ}\\\\So, X=15 \sin(3.14t+35.29^{\circ}) \ cm[/tex]

a lower frequency and a shorter wavelength.
a higher frequency and a longer wavelength.
a lower frequency and a longer wavelength.
a higher frequency and a shorter wavelength.
Answer:
A lower frequency and a longer wavelength is correct on edge 2021
please thank the person above me though, they deserve it.
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.
