Answer:
The vertical distance between these two points is 12.28 cm.
Explanation:
Given that,
Speed of water = 1.23 m/s
Diameter at lower point d'= 0.787 d
We need to calculate the speed of water
Using continuity equation
Put the value into the formula
We need to calculate the vertical distance h between these two points
Using Bernoulli theorem
Here, P₁ = P₂ = atmosphere pressure is same because both end is open
Hence, The vertical distance between these two points is 12.28 cm.
Hi there!
Impulse = Change in momentum
I = Δp = mΔv = m(vf - vi)
Where:
m = mass of object (kg)
vf = final velocity (m/s)
vi = initial velocity (m/s)
Begin by converting grams to kilograms:
1 kg = 1000g ⇒ 145g = .145kg
Now, plug in the given values. Remember to assign directions since velocity is a vector. Let the initial direction be positive and the opposite be negative.
I = (.145)(-20 - 17) = -5.365 Ns
The magnitude is the absolute value, so:
|-5.365| = 5.365 Ns
Answer;
- Rock layers are placed under compressional stress: Reverse Fault
- Rock layers are placed under tensional stress: Normal Fault
- Hanging wall has dropped relative to footwall: Normal Fault
- Hanging wall has risen relative to footwall: Reverse faults
Explanation;
A normal fault occurs because two tectonic plates are pulling apart from each other, causing tensional stress. The stress allows gravity to pull the hanging wall downward along the footwall, making a cliff-like formation called a scarp. Thus, if you see the hanging wall has dropped relative to the footwall, it is a normal fault. Normal faults occur at divergent boundaries.
A reverse fault happens at convergent boundaries, where two plates colliding produce compressional stress. As the two plates come together, the pressure causes the hanging wall to move upward along the footwall. These breaks are reverse faults because the hanging wall moves in an opposite, or reverse, direction when compared to a normal fault.
A strike-slip fault occurs when tectonic forces cause rock layers to break apart and move in opposite, parallel directions, causing shear stress. The rock layers in a strike-slip fault move sideways past one another.
Weight is a force caused by gravity. The weight of an object is the gravitational force between the object and Earth.
