Where does wave reflection occur?at boundaries between two different media
while a wave is propagating through a single media
when two waves moving in opposite directions collide
none of the above

Answers

The correct answer for the question that is being presented above is this one: "none of the above." Wave reflection happens there is a change in direction of a wavefront. This wavefront is at an interface between two different media, which makes the wavefront returns into where it is originated.

Answer:

The correct answer is actually "at boundaries between two different media"

Two aircraft leave an airfield at the same time. One travels due south at an average velocity of 85 m s 1and the second travels due east at an average velocity of 71 ms −1
. Calculate the distance between the planes after 6 hours. Give your answer in km, to the nearest km. km

Answers

Answer: 2392 kilometers.

Explanation:

To find the distance between the two aircraft after 6 hours, we can use the Pythagorean theorem because they are moving at right angles to each other (one due south and the other due east). Here's how to calculate it:

First, calculate the distance traveled by each aircraft in 6 hours.

1. Aircraft traveling south:

  Distance = Velocity × Time

  Distance = 85 m/s × (6 hours × 3600 seconds/hour)

  Distance = 85 m/s × 21600 s

  Distance = 1836000 meters

2. Aircraft traveling east:

  Distance = Velocity × Time

  Distance = 71 m/s × (6 hours × 3600 seconds/hour)

  Distance = 71 m/s × 21600 s

  Distance = 1533600 meters

Now, we have the two sides of a right triangle:

- The southbound distance is 1836000 meters.

- The eastbound distance is 1533600 meters.

We can use the Pythagorean theorem to find the hypotenuse (distance between the aircraft):

Distance = √(southbound distance² + eastbound distance²)

Distance = √((1836000 m)² + (1533600 m)²)

Distance ≈ √(3376416000000 m² + 2352089600000 m²)

Distance ≈ √(5728505600000 m²)

Distance ≈ 2391760.78 meters

Now, let's convert the distance to kilometers:

Distance ≈ 2391.76 kilometers

Rounding to the nearest kilometer, the distance between the two aircraft after 6 hours is approximately 2392 kilometers.

Develop a mnemonic for branches of physics.

Answers

Answer:

  1. For physics, a common mnemonic is "My Very Earnest Mother Just Served Us Nine Pizzas" to help remember the order of the planets in our solar system (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto).
  2. "SOH CAH TOA" - This helps remember the trigonometric ratios in a right triangle: Sine = Opposite/Hypotenuse, Cosine = Adjacent/Hypotenuse, Tangent = Opposite/Adjacent.
  3. "King Henry Died Drinking Chocolate Milk" - This is used to remember the metric system prefixes in order of magnitude: Kilo, Hecto, Deca, (Base Unit), Deci, Centi, Milli.
  4. "ROY G. BIV" - This helps remember the colors of the visible light spectrum: Red, Orange, Yellow, Green, Blue, Indigo, Violet.
  5. "F = ma" - This equation represents Newton's second law of motion, stating that Force equals mass times acceleration.
  6. "E = mc²" - This equation represents Einstein's theory of relativity, stating that Energy equals mass times the speed of light squared.
  7. "PEMDAS" - This mnemonic helps remember the order of operations in math: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).
  8. "VIRUS" - This helps remember the formula for Ohm's Law: V (Voltage) = I (Current) x R (Resistance) or V = IR.
  9. "KE = 1/2 mv²" - This mnemonic represents the formula for kinetic energy: Kinetic Energy = 1/2 x mass x velocity squared.
  10. "PE = mgh" - This helps remember the formula for gravitational potential energy: Potential Energy = mass x gravitational acceleration x height.
  11. "F = G(m₁m₂/r²)" - This mnemonic represents Newton's law of universal gravitation, where F is the force between two masses, G is the gravitational constant, m₁ and m₂ are the masses, and r is the distance between the centers of the masses.
  12. "P = IV" - This mnemonic helps remember the formula for power in an electrical circuit: Power = Current x Voltage.
  13. "E = hf" - This represents the formula for energy of a photon, where E is energy, h is Planck's constant, and f is the frequency of the electromagnetic wave.

A pendulum is used in a large clock. The pendulum has a mass of 2kg. If the pendulum is moving at a speed of 4.1m/s when it reaches the lowest point on its path, what is the maximum length of the pendulum?

Answers

There's no way to calculate the length of the pendulum
with the given information.

The only thing we can calculate is the total energy in the pendulum.

When the pendulum is at the bottom of its swing, ALL of its energy
is kinetic.

       Kinetic energy = (1/2) x (mass) x (speed)²

                             = (1/2) x  (2 kg) x (4.1 m/s)²

                             =    4.1  kg-m²/sec²

                             =    4.1 Joules .

In principle, we can also calculate how HIGH the 'bob' is at the end of
its swing, because now we know how much total energy the pendulum
has, and at the ends of the swing, the energy is all potential.

       Potential energy  =  (mass) x (gravity) x (height)

               4.1 J  =  (2 kg) x (9.8 m/s²) x (height)

               Height  =  (4.1 kg-m²/s²) / (19.6 kg-m/s²)

                           =    0.209 meter high

and that's as far as we can go.  None of this points us toward
calculating the length of the pendulum.
