Answer:
The correct answer is D. Creep.
Explanation:
Ground creep is a slow downward movement of a hill or mountain slope without the formation of demolition forms. The decisive factor for this is the continuous flow of movement of the soil.
The main driver of collapse is the movement of the surface layer particles during expansion in a direction perpendicular to the slope, followed by vertical collapse on contraction. The visible effect of the collapsing is the inclination of fences and poles, as well as trees that grow out of the ground towards the slope and have trunks curved vertically, in more extreme cases it may be cracks on the walls of buildings.

In Young's double slit experiment if the maximum intensity of light is Imax, then the intensity at path difference λ/2 will be
A .Imax
B .2Imax
C .4Imax
D. None
Answers
Answer:
Explanation:
When the path difference is half the wave length or λ /2 , destructive interference takes place which results in reduced or zero intensity in case equal intensity waves interfere as in Young's double slit experiment
Hence dark fringe is formed at that place where intensity is zero .
Hence the right option is D
3. Find the weight of ethanol that is inside a cylindrical can of diameter 5cm and a height of 50mm. The density of ethanol is 0.81 x 10 kg/m³
Answers
To convert this computed volume from mL to L, simply divide the provided quantity of ethanol by its density: 500g(mL0.789g)(L1000mL)=0.633L. 500g(mL0.789g)(L1000mL) = 0.633L.
Is ethanol bad for people?Ingestion, inhalation, and skin absorption of ethanol are all dangerous. Frequent contact can cause the skin to become dry, which can cause it to become itchy, crack, and peel. The central nervous system, the eyes, and the upper respiratory tract can all be affected by ethanol.

Many of the rocks of the canyon wall appear as horizontal bands. What do the bands indicate about the way the rocks formed?
Answers
Given what we know, we can confirm that the bands indicate that the canyon was carved due to erosion caused by moving water.
What do these bands tell us about the canyon?The bands are the result of sediments being deposited as the canyon was being formed. These sediments are deposited by the running water that carves the canyon. This results in horizontal bands that can tell us much about the history of the canyon as well as the river that formed it.
Therefore, we can confirm that the bands indicate that the canyon was carved due to erosion caused by moving water.

Leah was pulling on a wagon with a force of 156N at an angle of 38 degrees. if she moves the wagon 45.5m how much work has she done
Answers
Answer:
W = 5593.3 J
Explanation:
The work can be calculated as
W = Fdcosθ
Where F is the force, d is the distance and θ is the angle.
So, replacing F = 156N, d = 45.5 m and θ = 38, we get:
W = (156N)(45.5m)(cos38)
W = (156N)(45.5m)(0.788)
W = 5593.3 J

C. The universe may begin contracting due to gravity and lead to another big bang and continue this cycle over and over.
D. The mass of the universe is not large for its gravity to slow down the expansion, and it will continue indefinitely.
Answers
The open universe theory, states that the mass of the universe is not large enough for its gravity to slow down the expansion caused by the Big Bang, and it will continue expanding indefinitely.
What does the Open Universe Theory suggest?This theory also known as the unbounded or infinite universe theory suggests that the geometry of the universe is flat, meaning that parallel lines will never meet or intersect, and that the total energy of the universe is zero. In an open universe, the expansion will not stop, and galaxies will continue to move away from each other at an increasing rate. This theory is supported by observations of the cosmic microwave background radiation, which provide evidence for the early expansion of the universe.

Two cars collide head-on and stick together.
Car A, with a mass of 2000 kg, was initially
moving at a velocity of 10 m/s to the east. Car
B, with an unknown mass, was initially at rest.
After the collision, both cars move together at
a velocity of 5 m/s to the west. What is the
mass of Car B?
OF
Answers
The mass of Car B is -6000 kg.
To solve this problem, we can apply the principle of conservation of momentum, which states that the total momentum before the collision is equal to the total momentum after the collision.
Therefore, we can write the equation for the conservation of momentum as:
(mass of Car A * velocity of Car A) + (mass of Car B * velocity of Car B) = (mass of Car A + mass of Car B) * velocity after collision
Let's substitute the given values into the equation:
(2000 kg * 10 m/s) + (mass of Car B * 0 m/s) = (2000 kg + mass of Car B) * (-5 m/s)
Simplifying the equation:
20000 kg*m/s = -5 m/s * (2000 kg + mass of Car B)
Dividing both sides by -5 m/s:
-4000 kg = 2000 kg + mass of Car B
Subtracting 2000 kg from both sides:
mass of Car B = -4000 kg - 2000 kg
mass of Car B = -6000 kg

A photodetector has three polarizing films between it and a source of
unpolarized light. The first film is oriented vertically. At what angle should the
second polarizing film be oriented so that 37.5 percent of the original light
intensity reaches the detector?
Investigation 12 Electromagnetic Radiation
Answers
The angle between the polarization direction of the second film and the vertical direction should be approximately 51.4° so that 37.5% of the original light intensity reaches the detector.
Steps
Let's denote the angle between the vertical polarization direction of the first film and the polarization direction of the second film by θ. The transmitted intensity of the light after passing through the two films is given by Malus's law:
I = I₀ cos²θ
where I₀ is the initial intensity of the unpolarized light.
We want to find the angle θ that will result in 37.5% of the original light intensity reaching the detector. This means that we want to solve the equation:
I/I₀ = 0.375
Substituting the expression for I into this equation, we get:
cos²θ = 0.375 / I₀
Taking the square root of both sides and using the fact that cosθ is positive when 0 ≤ θ ≤ π/2, we get:
cosθ = √(0.375 / I₀)
θ = arccos(√(0.375 / I₀))
Now we need to substitute the values of I₀ and evaluate the expression for θ. Let's assume that the intensity of the original light is I₀ = 1 W/m². Then we get:
θ = arccos(√(0.375 / 1)) = arccos(0.6124) = 51.4°
Therefore, the angle between the polarization direction of the second film and the vertical direction should be approximately 51.4° so that 37.5% of the original light intensity reaches the detector.

Mrs Turner has a scale drawing of her apartment.IN the scale drawing the lenght of her apartment is 6.25 inches and the width is 2.75 onches. If Mrs. Turner used the scale factor 1 inc/18ft, what would the area of the apartment be?
Answers
The area of Mrs. Turner's apartment is approximately 0.05304 square feet.
To find the area of Mrs. Turner's apartment, we need to convert the measurements from the scale drawing to the actual measurements in feet, using the given scale factor of 1 inch/18 feet.
Length of apartment in feet = 6.25 inches × (1 foot/18 inches) = 0.34722 feet
Width of apartment in feet = 2.75 inches × (1 foot/18 inches) = 0.15278 feet
Now, we can calculate the area of the apartment in square feet by multiplying the length and width:
Area of apartment in square feet = Length × Width = 0.34722 feet × 0.15278 feet = 0.05304 square feet
Therefore, the area of Mrs. Turner's apartment is approximately 0.05304 square feet.

Given that the relative distance between 2 trains, d = 360 miles
Time, t is 5 hrs.
Let speed of freight train be v, then the speed of passenger train will be 3v.
For relative speed, the speed of trains will be added.
Hence,
\(\begin{gathered} 3v+v=\frac{360}{5} \\ v=\frac{360}{5\times4} \end{gathered}\)Thus, the speed of freight train is 18 miles/hour.
