Which landform is most likely formed from the destructive and constructive processes from wind forces?
A. Canyon
B.dunes
C. Mountain
D. Valley
Answer:
B.dunes
Explanation:
sand dunes are created by wind
The landform which is formed from the destructive and constructive processes of wind forces is dunes. Hence, option B is correct.
What is a landform?An anthropogenic or natural land feature on the solid surface of the Earth or another planetary body is referred to as a landform. A given terrain is made up of several landforms, and topography refers to how these landforms are arranged in the surrounding area. In addition to shoreline characteristics like bays, peninsulas, and seas, landforms also include hills, mountains, canyons, and valleys. Submerged structures like volcanoes, mid-ocean ridges, and major ocean basins are also considered to be landforms.
Physical characteristics of landforms, such as height, slope, orientation, stratification, rock exposure, and soil type, are used to classify them. Intuitive elements like berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and many more structural and size-scale elements, including different types of inland and marine waterbodies and sub-surface features, are all examples of gross physical features or landforms.
The landform made of wind are :
The erosional landform madeup of wind is Mushroom rock, zeugen, demoselles, yardang etc.

When forces of 5 N and 7 N respectively act on an object. When will the resultant of the two vectors be at a maxium
Answer:
F = 12 N
Explanation:
Given that,
Force of 5 N and 7 N respectively act on an object.
We need to find the resultant of the two vectors be at a maximum.
Force will be maximum when two forces acts in same direction. It means we can simply add them i.e.
F = 5 N + 7 N
F = 12 N
Hence, the resultant force is 12N.
The s.I unit of R so that the equation velocity= R × density S dimensionally correct R is a constant
Answer:
R = m⁴/kg . s
Explanation:
In this case, the best way to solve this is working with the units in the expression.
The units of velocity (V) are m/s
The units of density (d) are kg/m³
And R is a constant
If the expression is:
V = R * d
Replacing the units and solving for R we have
m/s = kg/m³ * R
m * m³ / s = kg * R
R = m * m³ / kg . s
R = m⁴ / kg . sThis should be the units of R

Answer:
Position A/Position E
[tex]K = E[/tex], [tex]U = 0[/tex]
Position B/Position D
[tex]K = (1-x)\cdot E[/tex], [tex]U = x\cdot E[/tex], for [tex]0 < x < 1[/tex]
Position C
[tex]K = 0[/tex], [tex]U = E[/tex]
Explanation:
Let suppose that ball-Earth system represents a conservative system. By Principle of Energy Conservation, total energy ([tex]E[/tex]) is the sum of gravitational potential energy ([tex]U[/tex]) and translational kinetic energy ([tex]K[/tex]), all measured in joules. In addition, gravitational potential energy is directly proportional to height ([tex]h[/tex]) and translational kinetic energy is directly proportional to the square of velocity.
Besides, gravitational potential energy is increased at the expense of translational kinetric energy. Then, relative amounts at each position are described below:
Position A/Position E
[tex]K = E[/tex], [tex]U = 0[/tex]
Position B/Position D
[tex]K = (1-x)\cdot E[/tex], [tex]U = x\cdot E[/tex], for [tex]0 < x < 1[/tex]
Position C
[tex]K = 0[/tex], [tex]U = E[/tex]
4. What is the consequence of atoms being a singular closed system?
Atoms of a certain element contain a fixed amount of energy.
Atoms of a certain element can't be altered by outside forces.
Atoms don't interact with each other in any way.
Atoms decompose slowly over time as they lose energy.
Answer:
*Atomos of a certain element contain a fixed amount of energy.
Explanation:
The atoms are said to be closed systems because the number of protons, neutrons and electrons is fixed, so these elements each have an energy given by the electrical interaction with the other elements.
Consequently, the correct answer is: Atomos of a certain element contain a fixed amount of energy.
Answer:
Atoms of a certain element contain a fixed amount of energy.

Tetra fish that live in caves are blind and have small eyes that do not work. This is an example of a vestigial structure.
A harbour seal's flipper and a human hand have a very similar structure, but function differently. This is an example of a Homologous structure.
What is vestigial structure?
Some organisms have elements that seem to be left over from an earlier ancestor but have no apparent purpose. For instance, because they are evolved from reptiles with legs, certain snakes have pelvic bones despite not having any. The human vermiform appendix is another instance of a structure that serves no purpose.
Vestigial structures are these inactive, purposeless structures. Other examples of vestigial structures are the wings of flightless animals like the ostrich, the leaves of some cacti, the remains of whale pelvic bones, and the eyes that are blind in cave mammals.

Which part of the drum vibrates when it produces sound?
Explanation:
For example, when a drum is struck, the flexible skin (sometimes called a membrane) of the drum vibrates. The compression and expansion of the air on either side of the vibrating membrane produces differences in air pressure. The pressure differences generate a sound wave that propagates outward from the drum surface.

If an object free-falls for t seconds from rest to d distance, how far will the object fall from rest in twice the elapsed time?
Answer:
When the time of fall is doubled, the height of fall will be quadrupled
Explanation:
Given;
height of fall, h = d m
time of fall, t = t s
initial velocity of the object, u = 0 m/d
The height of fall of the object is calculated from the kinematic equation below;
[tex]h = ut + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\2h = gt^2\\\\g = \frac{2h}{t^2}[/tex]
where;
g is acceleration due to gravity, which is constant
if the time of fall is doubled, the height of fall is calculated as;
[tex]\frac{2h_1}{t_1^2} = \frac{2h_2}{t_2^2} \\\\\frac{h_1}{t_1^2} = \frac{h_2}{t_2^2}\\\\(Note: h_1 = d, \ and \ t_1 = t)\\\\h_2 = \frac{h_1t_2^2}{t_1^2} \\\\h_2 = \frac{(d)(2t_1)^2}{t_1^2} \\\\h_2 = \frac{(d)(2t)^2}{t^2}\\\\h_2 = \frac{(d)\times 4t^2}{t^2}\\\\h_2 = 4d[/tex]
Therefore, when the time of fall is doubled, the height of fall will be quadrupled

the brake fluid? Even worse what would go wrong if the break fluid leaked out of its pipes?
Answer:
If it leaks....
If there is a brake fluid leak and air gets mixed with the fluid in the brake lines, then the fluid will not be able to flow correctly. As a result, when you press your foot down on the brake pedal, it will feel squishy or spongy. In other words, the brake pedal will feel very soft.
If air bubbles get into....
Air is the enemy in a hydraulic system because it reduces pressure and essentially makes the process less effective. When air gets into the brake lines, your brake system suffers. Symptoms that can indicate you have air in your brake lines include the following: Brake pedal feels spongy when you press down
