Answer:
0.91
Explanation:
as equivalence resistance can be found out using the
1/Req = 1/r1 +1/r2 +1/r3......
now, 1/req= 1/2+1/3+1/4
=6/12+4/12+3/12
=13/12
i.e, req =12/13 =0.91

B. Large cross-sectional area, long pipe
C. Small cross-sectional area, short pipe
D. Small cross-sectional area, long pipe
Explanation:
Conductance is a measure of how easily the current can flow through a electrical component.
It is the inverse of resistance.
Conductance is given by
where is conductivity(constant for a component), is the length of component parallel to the flow and is the area of cross-section of the component perpendicular to the flow.
So,conductivity increases with increase in and decreases with increase in
So,small cross-sectional area and long pipe has high conductance.
Answer: Diagnostic
Explanation: For sure!
Answer:
Heterogeneous
Explanation:
A chemical substance is composed of one type of atom or molecule. A mixture is composed of different types of atoms or molecules that are not chemically bonded. A heterogeneous mixture is a mixture of two or more chemical substances where the various components can be visually distinguished.
B. L = W; F = D
C. L = W = F = D
D. L = W; F > D
Answer:
(B) L=W; F=D
Explanation:
Since the airplane's velocity is constant, the airplane is not accelerating in any direction. In absence of acceleration, all forces acting on the plane are balanced so that the net forces in the horizontal and the vertical directions are zero. Given the drawing, this implies that
Forward force = Drag force (F=D)
Weight = Lift (W=L)
which corresponds to option (B)
(it is not C because nothing in the text says that the vertical and horizontal components have to have same magnitude)
The relationship between the magnitudes of the forces is that lift force is equal to weight force, and drag force is equal to thrust force.
In this scenario, the airplane is flying at a constant velocity, which means that its acceleration is zero. According to Newton's first law of motion, if an object is moving with a constant velocity, the net force acting on it is zero.
Therefore, the relationship between the magnitudes of the four forces shown in the diagram is that the lift force (L) is equal to the weight force (W), and the drag force (D) is equal to the thrust force (F).
So, the correct answer is C. L = W = F = D.

When heavy rain follows a dry season in the mountains, the land can change abruptly. For example, a mudslide can rush downhill as a huge mass of soil, water, and rock leaves a bare scar on the hillside. The correct option is A.
A mudslide, also known as a debris flow or a landslide, is a rapid movement of a large mass of soil, rock, and water down a steep slope or hillside.
Mudslides typically occur after heavy rain, when water rapidly saturates the soil and creates a slurry of mud and debris. This slurry then flows downhill at high speeds, carrying with it anything in its path, such as rocks, trees, and buildings. Mudslides can be extremely destructive and dangerous, and they can cause significant damage to homes, infrastructure, and the natural environment.
Mudslides can occur in various parts of India, particularly in areas with hilly terrain and heavy rainfall. Some of the regions where mudslides have been known to occur in India are:
Uttarakhand: This northern state is particularly prone to mudslides and landslides, with the 2013 Uttarakhand floods and landslides being one of the worst disasters in recent history.
Himachal Pradesh: Another northern state with hilly terrain, Himachal Pradesh has also experienced numerous mudslides and landslides in the past.
Jammu and Kashmir: This state in the north of India is also prone to landslides and mudslides, particularly in the hilly areas.
Northeast India: The northeastern states of India, such as Meghalaya, Arunachal Pradesh, and Assam, are also prone to landslides and mudslides due to their hilly terrain and heavy rainfall.
Western Ghats: The Western Ghats, a mountain range that runs along the western coast of India, is also known for landslides and mudslides during the monsoon season.
It's important to note that mudslides can occur in other parts of India as well, and it's always important to be aware of the risks and take appropriate precautions.
Therefore, mudslide is the correct option i.e A.

Answer:
Explanation:
This abrupt change can alter the surface, like mudslides, they are formed of water, rocks and water, like is described. This mudflow is capable to destroy vegetation, and leave behind fissures.
