Explanation:

Clean Energy Source It generates more than 800 billion kilowatt hours of electricity each year and produces more than half of the nation's emissions-free electricity. This avoids more than 470 million metric tons of carbon each year, which is the equivalent of removing 100 million cars off of the road.

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.

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.

thats the answer

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]

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.

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.

vestigial structure

Homologous structure

Explanation:

Did the assignment.

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.

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.

#SPJ5

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

This should be the units of R

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
