Of the nine components of total-stress tensor, only 6 are independent
T/F
True.
The total-stress tensor in three dimensions is made up of nine elements. The stress tensor, on the other hand, is a symmetric tensor because of the conservation of angular momentum, which means that the elements are not all independent.
The stress tensor specifically consists of six off-diagonal (shear stresses) and three diagonal (normal stresses) components.
Three pairs make up the off-diagonal components, and because of the symmetry, each pair is equal.
Therefore, only six of the nine components of the total-stress tensor are independent.

When there's a wind blowing does a round trip by plane take more time less time or the same time?
Headwinds during takeoff help to boost lift, requiring a record low speed as well as a shorter airfield distance for the aircraft to take flight. Similar benefits can be found when landing towards the wind, including a smaller landing area and slower ground speed.
Explain the effects of Wind on Aircraft?It should come as no surprise that the wind is one of the main factors influencing an aircraft's movements while in flight.
Given that an aircraft rarely flies in the exact same directions as the wind, it is required for an aircraft to continuously correct for both wind patterns as well as wind speed in order to keep its desired course while in flight.Even though an airplane has its own method of propulsion, the wind's strength and direction can considerably affect how far an aircraft travels while in flight; this is known as the "wind effect." Therefore, its forward motion or force of the airplane through into the air and indeed the natural flow of that air decide whether or not the aircraft stays on to its intended flight route (wind).Thus, a round-trip flight takes longer and takes less time when the wind is blowing.

A student tosses a ball horizontally from a balcony to a friend 3.8 meters down below them. How long does the ball take to reach their friend?
Answer:
The time it takes the ball to fall 3.8 meters to friend below is approximately 0.88 seconds
Explanation:
The height from which the student tosses the ball to a friend, h = 3.8 meters above the friend
The direction in which the student tosses the ball = The horizontal direction
Given that the ball is tossed in the horizontal direction, and not the vertical direction, the initial vertical component of the velocity of the ball = 0
The equation of the vertical motion of the ball can therefore, be represented by the free fall equation as follows;
h = 1/2 × g × t²
Where;
g = The acceleration due gravity of the ball = 9.81 m/s²
t = The time of motion to cover height, h
Then height is already given as h = 3.8 m
Substituting gives;
3.8 = 1/2 × 9.81 × t²
t² = 3.8/(1/2 × 9.81) ≈ 0.775 s²
∴ t = √0.775 ≈ 0.88 seconds
The time it takes the ball to fall 3.8 meters to friend below is t ≈ 0.88 seconds.

glacial deposits consist primarily of __________.group of answer choicesvery coarse-grained materialvery well-sorted materialvery poorly sorted materialvery fine-grained material
Glacial deposits consist primarily of c. very poorly sorted material.
This means that the sediment contained in glacial deposits varies greatly in size, ranging from boulders to fine-grained silt and clay particles. This is because glaciers are capable of eroding, transporting, and depositing a wide range of sediment sizes as they move across the landscape. The process of glacial erosion involves the grinding and crushing of rocks, which creates a mixture of angular and rounded particles.
As the glacier melts, it deposits this mixture of sediment, resulting in a haphazard and disorganized arrangement of particles. This can make it difficult to determine the exact composition of glacial deposits, as the sediment can vary greatly even within a single deposit. However, the poorly sorted nature of glacial deposits is a key characteristic that distinguishes them from other types of sedimentary deposits. So therefore the correct answer is c. very poorly sorted material, is the glacial deposits.

Give numerical answers to the following questions to the extent pos-sible and state your reasoning about what happens to the wave physically. (b) What happens to its frequency?
To summarize, as the sound wave passes through the region with changing temperature, its frequency remains the same, but its wavelength changes due to the change in the speed of sound.
When a sound wave propagates through a region where the temperature gradually changes, its frequency can be affected. In this scenario, the sound wave starts at 27°C with a frequency of 4.00kHz and then moves through air at 0°C.
As the temperature changes, the speed of sound in air also changes. The speed of sound is directly proportional to the square root of the temperature. So, as the temperature decreases from 27°C to 0°C, the speed of sound decreases as well.
The frequency of a sound wave remains constant as it travels through different mediums. Therefore, the frequency of the sound wave will not change as it passes through the region with changing temperature.
However, the wavelength of the sound wave will change, since wavelength is inversely proportional to the speed of sound.

If the loop the car is currently on has a radius of 18.0 m , find the minimum height h so that the car will not fall off the track at the top of the circular part of the loop.
The minimum height required for the car to not fall off the track at the top of the circular part of the loop is 1 meter.
To determine the minimum height required for the car to not fall off the track at the top of the circular part of the loop, we need to consider the forces acting on the car at that point.
At the top of the loop, the car is experiencing two forces: the gravitational force (mg) acting downward and the centripetal force (mv²/r) acting inward. For the car to remain on the track, the centripetal force must be greater than or equal to the gravitational force.
Let's calculate the minimum height using this information.
Given:
Radius of the loop (r) = 18.0 m
At the top of the loop, the net force acting on the car is the centripetal force minus the gravitational force:
mv²/r - mg ≥ 0
We can rearrange this equation to solve for the minimum height:
mv²/r ≥ mg
v² ≥ rg
v = √(rg)
where v is the speed of the car.
To avoid complicating the calculation with the car's speed, we can assume the car is just at the point of leaving the track at the top of the loop, so it is not accelerating (v = 0).
In this case, the centripetal force is zero, and the gravitational force is the only force acting on the car.
mg ≥ 0
Therefore, the minimum height required can be found by equating the gravitational potential energy (mgh) to the gravitational force (mg):
mgh = mg
Canceling out the mass (m) from both sides of the equation, we have:
gh = g
Simplifying further:
h = 1
Therefore, the minimum height required for the car to not fall off the track at the top of the circular part of the loop is 1 meter.

A variable capacitor with a range from 12 to 279 pF is used with a coil to form a variable-frequency LC circuit to tune the input to a radio. (a) What is the ratio of maximum frequency to minimum frequency that can be obtained with such a capacitor
The ratio of maximum frequency and minimum frequency is 4.9.
Calculation:
The relation between frequency, f, and conductance, C and inductance, L is given as:
\(f = \frac{1}{2\pi \sqrt{LC} }\)
Given,
Cmax = 279 pF
Cmin = 12 pF
The smaller value of C gives the the larger value of f, therefore,
\(fmax = \frac{1}{2\pi\sqrt{LCmin} }\) ....(1)
\(fmin = \frac{1}{2\pi\sqrt{LCmax} }\) .....(2)
Dividing both the equations (1) and (2):
\(\frac{fmax}{fmin} =\frac{\sqrt{Cmax} }{\sqrt{Cmin} }\)
\(\frac{fmax}{fmin} = \frac{\sqrt{279} }{\sqrt{12} }\)

An observer watching a sailing ship at sea notes that the ship appears to be "sinking" as it moves away . which statement best explains this observation? A, The earth is revolving B, The earth is rotating C, The earth has a curved surface D, The surface of the ocean has depressions
The statement that best explains this observation is "The earth has a curved surface."The correct option is C.
As the ship moves away from the observer, its distance from the observer increases, and the angle between the observer's line of sight and the ship's hull decreases. At some point, the ship's hull disappears below the horizon, and only its mast and sails are visible. This phenomenon occurs because the surface of the Earth is curved, and the observer's line of sight becomes tangent to the surface at some distance away from the observer. The curvature of the Earth causes the observer's line of sight to intersect the surface of the ocean at a greater distance from the observer as the ship moves away, making it appear as if the ship is sinking.
The other options are not true because:
A. The Earth's revolution around the sun does not affect the observer's line of sight to the ship.
B. The Earth's rotation causes the apparent motion of celestial objects, but it does not cause the observed sinking of the ship.
D. The surface of the ocean having depressions does not cause the observed sinking of the ship, as the phenomenon occurs even in calm seas with a uniform surface.
Therefore, The correct answer is Option C.

A roller skater with a mass of 71.2 kg is moving along the ice with a speed of 6.01 m/s. She collides head-on with a stationary skater who has a mass of 55.9 kg After the collision, the two skaters grab onto each other (without spinning or losing their balance) and move together. What is their speed?
Therefore, the speed of the two skaters after the collision is 3.37 m/s. The total momentum of the system before the collision is equal to the total momentum of the system after the collision.
We can set up an equation to solve for the final velocity of the two skaters:
(mass of skater 1 x velocity of skater 1) + (mass of skater 2 x velocity of skater 2) = (total mass of skaters x final velocity of skaters)
(71.2 kg x 6.01 m/s) + (55.9 kg x 0 m/s) = (71.2 kg + 55.9 kg) x final velocity
