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.

Answer:

a.

Explanation:

Answer:

I am pretty sure it is C!

Explanation:

According to www.open.edu,

Elements are substances that are made from one type of atom.

Compounds are substances made from atoms of different elements joined by chemical bonds.

A mixture is made by simply mixing together elements and compounds.

Atoms are the basic building blocks.

i think A is incorrect because, while the statement may be correct, it is talking about Mixtures, not elements themselves!

B is incorrect because elements ARE able to combine to form compounds!

D is incorrect because ELEMENTS combine to create compounds, i am pretty sure compounds don't combine to create elements.

Explanation:

Range of a projectile is given by; U^2sin2θ/g

When θ = 45°

The maximum range is obtained as;

Rmax = U^2/g

Maximum range on earth = RME = U^2/g

Maximum range in the moon= RMM =U^2/g/6

Maximum range in Mars = RMMA = U^2/0.38g

a)

RME/RMM =  U^2/g/U^2/g/6

RME/RMM = 6

But RME = 3 m

RMM = 3 * 6 = 18 m

b)

RME/RMMA =U^2/g/U^2/0.38g

RME/RMMA = 1/0.38

But RME = 3 m

RMMA = 3/0.38

RMMA = 7.9 m

Answer:

The radius of the curve is 9,183.67 m.

Explanation:

Given;

velocity of the jet plane, v = 600 m/s

acceleration of the jet plane, a = 4g = 4 x 9.8 m/s² = 39.2 m/s²

The radius of the curve is calculated from centripetal acceleration formula as given below;

[tex]a = \frac{v^2}{r} \\\\r = \frac{v^2}{a} \\\\r = \frac{600^2}{39.2} \\\\r = 9,183.67 \ m[/tex]

Therefore, the radius of the curve is 9,183.67 m.

I can't transpose the diagram onto Brainly. I'll do my best to describe what is going on.

Now you are ready to develop the equation

Clockwise

There is only 1 force where B is the Balance point that is going clockwise

10 * Force A

The AntiClockwise Moments

Platform: 4*10kg * 9.8 = 392 N m

Physics T: 2 * 75 * 9.8 = 1470 N m

So the Anti Clockwise moments = the clockwise moments.

10 * Force A = 392 NM  + 1470NM   Divide by 10. Remember that is in meters

Force A = 1862 N M / 10 10 M = 186 N

Does that make some sort of sense? It should Student A is the furthest distance from where all the action is at B. Therefore he is carrying the lightest weight.

Now what is the total force?

(75 + 10 ) * 9.8 = 85 * 9.8 = 833

This is one of those strange things that won't make sense until it does. Read the next sentence carefully. B is carrying most of the weight. Remember Newtons measure weight.

Support of A = 186 N

Support of B = x

Total of A+B = 933

186 + x = 833

x = 933 - 186

x = 647

So the forces are

A supports    186

B supports    647

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.

Explanation:

Answer:

See answer below

Explanation:

In order to do this, we just need to apply the expression to determine the time of flight. This is given by:

t = 2 V₀ Sinθ / g   (1)

We have the initial speed which is 200 m/s, the angle of elevation to the horizontalis 60° and the gravity is 9.8 m/s². Replacing this data in the above expression we have:

t = 2 * 200 Sin60° / 9.8

Now that we have the time, we can determine the range or distance in the horizontal plane. This can be calculated using the following expression:

X = V * t   (2)

We already have the time, which is the time of flight, the initial speed using cos 60° (Cause it's horizontal plane), and replacing we have:

X = 200 cos60° * 35.348

X = 100 * 35.348

Kinetic energy and velocity are at zero when the magnets are held apart, and both increase rapidly when they are released and move together. Energy stored in the magnetic field decreases.

Graph for the two magnets held apart, kinetic energy is highest when the magnets first released, then it decreases steadily. Energy stored in the magnetic field becomes zero.

The magnetic field is the field in the space and around the magnet in which the magnetic field can be filled.

Magnetic force is the force of attraction or repulsion between two poles of the two magnets. The magnetic force is also appearing between two electrically charged bodies.

Two magnets held apart. Once released, the south pole of one magnet moves toward the north pole of another magnet until the magnets collide.

First you need to find the acceleration

[tex] acceleration = \frac{8 - 0}{22} [/tex]

that gives you 0.36 recurring(on both numbers) m/s²

mass= force ÷ acceleration

[tex] mass = \frac{31}{0.36recurring} [/tex]

mass= 85.25 kg

if you want to check

f=ma

85.25 × 0.36 recurring (remember its on both numbers not just 6) = 31 N

Answer:

Explanation:

Givens

F = 31 N

vi = 0

vf = 8 m/s

t = 22 seconds

m = ?

Formula

F = m ( vf - vi)/t

Solution

31 = m (8 - 0) / 22             Multiply both sides by 22

31 * 22 = 8 * m

8m = 682                          Divide by 8

m = 682 / 8

m = 85.25

Answer:

F1 = 16 N and F2 = 24 N

Explanation:

Formula used => F = m×a and v-u= at

So, as we know force = mass × acc.

so acc. of first block = <math> F1/5 </math>. and acc. of second block = <math> F2/ 8 </math>.......... so as v-u= at.. now

Here u= 0 as the objects are placed at rest initially..

thus, v= at

FOR 1ST BLOCK

16= <math> F1/5 </math> × 5 ==> F1 = 16 N

FOR 2ND BLOCK

15= <math> F2/ 8 </math> × 5 ==> F2= 24 N

Answer:

We need to find the kinetic energy of the girl before she hits the water. At this point the kinetic energy becomes equal to the potential energy such that,

[tex]K=mgh\\\\K=50\times 9.8\times 5\\\\K=2450\ J[/tex]

So, her kinetic energy right before she hits the water is equal to 2450 J.
