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.

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.
A jet plane flying 600 m/s experiences an acceleration of 4g when pulling out of the dive. What is the radius of curvature of the loop in which the plane is flying?
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.
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

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.

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]

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.

A rocket is fired at 60 to the horizontal with an initial speed of 200m5 calculate it time of flight and it range on the horizontal plane
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
t = 35.348 sNow 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
X = 3534.8 mHope this helps

(a) If a person can jump a maximum horizontal distance (by using a 45° projection angle) of 3.0 m on Earth, what would be his maximum range on the Moon, where the free-fall acceleration is g/6 and g 5 9.80 m/s2 ? (b) Repeat for Mars, where the acceleration due to gravity is 0.38g.
Answer:
See explanation
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

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

Two objects of mass 5 kg and 8 kg at rest F1 and F2 meters force applied on both the boxes respectively If the speed of both the objects after 5 sec become 16m/s and 15m/s respectively find the value of F1 and F2?
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
