Answer:
Deposition
Explanation:
Deposition occurs when water slows or ceases moving, the wind dies or stops blowing, or glaciers melt. The deposited material can also be used to construct new landforms. Waves, for example, can dump sediment in places offshore, where it might accumulate to form sand dunes.When the wind calms down or vegetation stops or slows the breeze, the sediment particles begin to fall. Water is another factor that may erode, move, or deposit sediment. Flowing water is a key erosive agent. Water transports dirt and rock fragments as it moves. Warm, wet air will not travel if wind systems are not present. Water will still evaporate, but it will not move, therefore everywhere else than a major body of water will dry up. Lakes may be fine since evaporating water will flow back into them, and the sea will be fine, but everywhere else will become extremely dry very rapidly. Wind is constantly blowing somewhere on the world at any given time. Winds are usually quiet near the middle of a high pressure system. Wind is the passage of air from a high pressure location to a low pressure area.... So essentially air is always moving. Weathering and erosion are caused by wind. Weathering is caused by wind blowing debris against cliffs and huge rocks. This wears down the rock, reducing it to sand and dust. Sand and dust are also eroded by wind. 2. Rocks are tough and durable, but they don't last forever. Weathering and erosion are processes that occur as a result of forces such as wind and water breaking down rocks. Weathering is the process through which rocks deteriorate. Weathering is caused by a variety of factors, including climate change.
Deposition occurs when wind dies down or stops blowing happens.
What is deposition?Deposition refers to the depositing of sediment carried by wind, flowing water, the sea, or ice. Sediment can be carried in the form of pebbles, sand, and mud, or as salts dissolved in water. Organic activity may later deposit salts.
The fractured rock fragments or soil particles are accumulated in an environment where the energy of the flowing river is reduced. It settles the particles, which compact and form sedimentary rocks over time.
Deposition can occur when a river enters a shallow area of water or when the volume of water decreases, such as after a flood or during a drought. Deposition is common at the mouth of a river near the end of its journey.
Thus, the answer is deposition.

force of 187 N acts on a 7.3 kg bowling ball for 0.40 s.
1. What is the change in momentum of the ball?
2. What is its change in velocity?
Change in momentum of the ball is 74.8 kg m/s
change in velocity of the ball is 0.25 m/s
What is change in momentum?
Change in momentum is the product of mass and change in velocity this is also equal to impusle which ia a product of force and time.
Change in momentum = m ( v - u ) = Impulse = f * t
m = mass
change in velocity = v - u
v = final velocity
u = initial velocity
f = force
t = time
Given:
f = 187 N
m = 7.3 kg
t = 0.40 s
!.
Change in momentum = impulse = f * t
Change in momentum = 187 * 0.40
Change in momentum = 74.8 kg m/s

Answer:

Explanation:
An athlete needs to get across a river. She must reach from point A on one bank to point B, which is directly across from point A on the opposite bank. If she wishes to minimize the total time T it would take to do so, at what angle upstreams (measured from the line AB) should she swim? Let her swimming/rowing speed relative to the water be 2.0 mi/h, and her running speed along the bank be 5 mi/h. The river flows downstream at 1.5 mi/h. (The rule of the competition stipulates that the athletes must swim first from point A, then run to reach point B.)
Answer:
θ = 90°
Explanation:
Speed at which she can swim in stationary water; v_m = 2 mi/h
Speed at which the river is flowing downstream; v_r = 1.5 mi/h
This can be illustrated in a form of triangle as attached. Where θ is the angle to the x-axis.
With respect to the bank of the river, the total speed of the girl is;
V_R = v_r + v_m
Now the horizontal component is;
V_R = v_r + v_m(cos θ)
While the vertical component is;
V_R = v_m(sin θ)
Now, the total time taken to get across the river is;
T = width of river/vertical component of total speed
Let's denote width of river as d.
Thus;
T = d/(v_m(sin θ))
Now, we are told she wishes o minimize the total time(T) .
Since the width(d) of the river is constant, and v_m is fixed, then it means the only variable we have is the angle θ.
Now, for the total time to be minimized, the denominator has to be at maximum.
Since angle θ is the only one that is variable, we have to find the value of angle θ that will make sin θ to be at a maximum value.
Now, for sin θ to be maximum, it means it has to be equal to 1.
Thus, θ = sin^(-1) 1
θ = 90°

A transformer has 500 volts applied to the primary side and 10,000 volts are measured
on the secondary side. If 10mA is applied to the primary side. What is the anticipated
current on the secondary side? Is this a step-up or step down transformer?
Answer:
0.5 mA, step-up transformer
Explanation:
Power is constant
V * I = constant
500 V * 10 mA = 10,000 V * I
so I = 0.5 mA
From 500 V increases to 10,000 V, so it is a step-up transformer

Rihanna can go from 0-60 miles per hour in 3.5 seconds. Calculate the acceleration.
Please show ALL work and CIRCLE your answer.
Answer:
7.66 m/s²
Explanation:
The following data were obtained from the question:
Initial velocity (u) = 0 mph
Final velocity (v) = 60 mph
Time (t) = 3.5 s
Acceleration (a) =.?
Next, we shall convert mile per hour (mph) to metre per second (m/s). This can be obtained as follow:
Recall:
1 mph = 0.447 m/s
Initial velocity (u) = 0 mph
Initial velocity (u) = 0 × 0.447 = 0 m/s
Final velocity (v) = 60 mph
Final velocity (v) = 60 × 0.447 = 26.82 m/s.
Finally, we shall determine the acceleration of Rihanna as follow:
Initial velocity (u) = 0 m/s
Final velocity (v) = 26.82 m/s.
Time (t) = 3.5 s
Acceleration (a) =.?
a = (v – u) /t
a = (26.82 – 0) / 3.5
a = 26.82 / 3.5
a = 7.66 m/s²
Thus, the acceleration of Rihanna is 7.66 m/s²
A boulder of mass 4 kg rolls over a cliff and reaches the beach below with a velocity of 20 metres per second minus 1.
what is the kinetic energy of the boulder when it lands?
what is the potential energy on the cliff?
How high is the cliff??
Given:-
Mass of boulder = 10kg
Final Velocity = 15m/s
Acceleration due to gravity = +10m/s
To Find:-
The kinetic energy of the boulder as it lands
The potential energy of the boulder when it was at the top of the cliff
The height of the cliff
Formulae used:-
Kinetic energy = mv²/2
Potential energy = mgh
Now,
We will first find the Kinetic enrgy,
→ K. E = ½mv²
→ K. E = ½ × 10 × (15)²
→ K. E = 5 × 225
→ K. E =1125J
But we know that when the body starts moving the Potential enrgy of the body starts Converting into Kinetic enrgy. Before reaching to the last spot it has equal kinetic energy and Potential energy.
Therefore,
→ mgh = 1125J
The Potential enrgy of the boulder when it was on top is 1125J
Now,
→ mgh = 1125J
→ 10 × 10 × h = 1125J
→ 100h = 1125J
→ h = 1125/100
→ h = 11.25m
Hence, The Height of the Cliff is 11.25m
