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.

A stone is dropped from a tower 100 meters above the ground. The stone falls past ground level and into a well. It hits the water at the bottom of the well 5.00 seconds after being dropped from the tower. Calculate the depth of the well. Given: g = -9.81 meters/second2.

Answers

The distance that an object falls from rest in ' T ' seconds is

   Distance = (1/2) (gravity) ( T² )

In this question,

   Distance = (1/2) (9.81 m/s²) (5.00 s)²

   =    (4.905 m/s²) (25.0 s²)

   =    (4.905 x 25) m

   = 122.63 meters .

The first 100 meters of fall was from the tower to ground level,
so the distance into the well must be the remaining 22.63 meters.

Answer:

22.5 meters

What instrument converts electrical energy to sound or image signals in a radio or television?

Answers

Answer:

In a radio or television, the instrument that converts electrical energy into sound signals or image signals is called a transducer. Transducers are devices that can convert one form of energy into another.

In the context of television, a television camera is an example of a transducer that converts light energy (captured through a lens) into electrical signals representing images or video. These electrical signals can then be processed and transmitted for display on a television screen.

In the context of a radio, a microphone is an example of a transducer that converts sound waves (acoustic energy) into electrical signals. These electrical signals, which represent sound, can then be amplified, modulated, and broadcast over the radio waves for reception by a radio receiver.

So, depending on whether you're referring to a television or a radio, the specific transducer used for converting electrical energy to sound or image signals may vary, but the concept of a transducer applies to both.

Explain why it’s hurt more carrying a heavy bag with a string of wire

Answers

Explanation:

Carrying a heavy bag with a string of wire can cause more pain compared to carrying a bag without a string of wire due to a few reasons.

Firstly, the presence of the string of wire adds additional pressure and strain on your hand, making it harder to grip and carry the bag comfortably. The wire can dig into your skin and cause discomfort or even pain. Imagine holding a bag with a smooth handle versus holding a bag with a sharp wire cutting into your hand - the latter would definitely be more painful.

Secondly, the wire can create friction against your skin. As you carry the bag and walk, the movement can cause the wire to rub against your hand, resulting in irritation and potentially even blisters. This friction can also cause the wire to dig deeper into your skin, intensifying the pain.

Lastly, the weight distribution of the bag can be affected by the presence of the wire. When you carry a heavy bag, it is ideal for the weight to be evenly distributed to minimize strain on specific areas of your body. However, the wire can create an uneven distribution of weight within the bag. This can lead to increased pressure and discomfort on certain parts of your hand, making it more painful to carry the bag.

In summary, carrying a heavy bag with a string of wire can hurt more due to the additional pressure and strain on your hand, the friction caused by the wire rubbing against your skin, and the uneven weight distribution within the bag. It is important to consider these factors when carrying heavy objects to minimize discomfort and potential injury.

Select all of the answers that apply.Thermohaline circulation is driven by _____.
density
salinity
temperature
wind
Coriolis effect

Answers

The correct answer for the question that is being presented above is this one: "density, salinity, temperature." Movement of deep ocean water driven by differences in temperature, salinity, and density cause the Thermohaline circulation. Thermohaline circulation is a part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and freshwater fluxes.

Final answer:

Thermohaline circulation is driven by density, salinity, and temperature. These factors cause changes in the water's density, leading to the creation of ocean currents.

Explanation:

Thermohaline circulation is primarily driven by density, salinity, and temperature. Salinity and temperature affect the density of ocean water, with higher salinity and lower temperature leading to a denser substance. When water in an area of the ocean becomes denser than the surrounding water, it sinks, creating a current. This process is global, meaning it involves the entire ocean system and thus is an essential part of Earth's climate.
