Both trains have the same speed and are approaching each other.

They both have to cover 8.5km, and since they are going the same speed they need to cover half the distance each (4.25km)

So, how long will it take a train going 155km/h to travel 4.25km?

The ratio of

There are 60 x 60 seconds in one hour (3600 seconds)

[tex]\frac{155km}{3600 seconds} = \frac{4.25km}{x seconds}[/tex]

Solve for x to get 98.7 seconds

We can do this by flipping both sides of the ratio

[tex]\frac{3600 s}{155 km} = \frac{x seconds}{4.25 km}[/tex]

Multiply both sides by 4.25km

4.25 ×  [tex]\frac{3600 s}{155 km} ={x seconds}[/tex]

Our unknown x = 98.7 seconds

Researchers believe that sleep helps strengthen and enhance long-term memory function. Hence, option B is correct.

Meditation could be thought of as a series of practices that encourage enhanced awareness and focused attention. Meditation is a different way to change awareness that has been shown to have several benefits for psychological well-being.

To feel refreshed and alert when you get up, sleep is a crucial process that allows your body and mind to heal. The body needs adequate sleep to remain healthy and free of disease. Without enough sleep, the brain cannot work efficiently. This may affect your ability to concentrate, think clearly, and process memories.

That's the reason researchers believe that sleep help in enhancing longer memory function.

The important thing to remember is that gravity is neither a push nor a pull; what we interpret as a “force” or the acceleration due to gravity is actually the curvature of space and time — the path itself stoops downward.

Answer:

The correct answer is C - 7.8 < 7 5/6 < 7.9

Step-by-step explanation:

First, convert 7 5/6 to decimal form --> 7.83.

If you don't know how to convert, think about what 5/6 is equal to and put it in decimal form. Add your decimal to the whole number, and there is your answer.

7.83 is in between 7.8 and 7.9, so it must be the answer.

Answer:

Explanation:

T = (2π rad / rev) / (25 rad/s) = 0.251327... = 0.25 s

The propeller was turning at 25 rad/s then the period of the propeller will be equal to 0.25 seconds.

In terms of physics, velocity is a vector assessment of the motion's direction and speed. The rate of change in an object's position relative to a reference frame and time is the more precise definition of velocity. Simply put, the concept of velocity informs us of the rate at which an object is travelling in a given direction.

It indicates the rate of motion of objects. Take two moving things like our illustration. If both items are travelling in the same vague direction, it is simple to determine which is moving more quickly.

From the given data in the question,

T = 2π (rad/rev) / 25 (rad/s)

T = 0.25 seconds.

Therefore, the period of this propeller is 0.25 seconds.

Explanation:

The normal force will be perpendicular to the motion. A zero-work situation is one where "a force everywhere perpendicular to the motion does no work" so according to this principle, no work is done.

The work done by the normal force n when the box slides down a frictionless incline and gaining speed is zero.

The force of contact is called the normal force. When the two surfaces are in contact with each other, then the normal force acts.

This force is applied by the solid bodies on each other in order to prevent the passing through each other.

A box slides down a frictionless incline, gaining speed. For this box, the value of work done by normal force has to be found out. Let's analyze the given condition.

Thus, the work done by the normal force n when the box slides down a frictionless incline and gaining speed is zero.

Answer:

the answer is White dwarf

Explanation:

Answer:

Explanation:

The resistor R2 is shorted out, so is not in the circuit. The remaining resistors are in a series circuit with a total resistance of ...

  R1 +R3 +R4 = 1k +4.7k +1k = 6.7k

The current is the ratio of the applied voltage to this total resistance:

  I = V/R = (9 v)/(6.7k) ≈ 1.3433 mA

The voltage across each resistor is the product of this current value and the resistance:

  R1 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

  R2 voltage = 0

  R3 voltage = (4.7 kΩ)(1.3433 mA) = 6.3134 volts

  R4 voltage = (1 kΩ)(1.3433 mA) = 1.3433 volts

The force applied to the submerged rubber duck is 4.9 N.

The density of the rubber duck is calculated as follows;

ρ = 0.2 x 1000 kg/m³

ρ = 200 kg/m³

F = mg = (ρV)g

F = (200 x 0.0025) x 9.8

Answer:

250 million years is called a cosmic year  because - D) That’s the amount of time it takes the solar system to revolve around the Milky way core.

Explanation:

The planets in our solar system orbit around the sun. ... Even at this blazing speed, it takes the sun approximately 225-250 million years to complete one journey around the galaxy's center. This amount of time – the time it takes us to orbit the center of the galaxy – is sometimes called a cosmic year.

The cosmic year is of 250 million years because that is the amount of time it takes in the solar system to revolve around the milky way core. Hence, option D is correct.

A large spiral galaxy known as the Milky Way contains the Sun and several hundred billion other stars. It gets its name from the Milky Way, an amorphous belt of stars and gas clouds that can be viewed in the sky from Earth. Astronomers do not fully comprehend the nature of the Milky Way Galaxy, which is commonly referred to simply as the Galaxy, despite the fact that Earth is located within it.

Much of the Galaxy is hidden by a thick layer of interstellar dust that prevents optical telescopes from seeing it, and astronomers can only determine its large-scale structure with the help of radio and infrared telescopes that can detect the types of radiation that can pass through the obscuring matter.

Our solar system's planets revolve around the sun. Even at this incredible speed, one orbit of the galaxy's center takes the sun about 225–250 million years to complete. A cosmic year is another name for the period of time it takes for us to orbit the galactic center.

During hypnosis, people  temporarily suspend their sense of initiative. Hence, option (C) is correct.

According to one definition, hypnosis is "a waking state of awareness, (or consciousness), in which a person's attention is diverted from his or her immediate surroundings and is consumed by interior experiences such as feelings, cognition, and images." In order to induce hypnosis, the subject must concentrate and become sufficiently absorbed in their imagination. A hypnotic world is created by the physician and patient through the use of suggestions and their acceptance.

Our everyday 'trance' states include things like becoming lost in a good book, driving down a familiar route without being aware of it, being in prayer or meditation, or engaging in a mindless or creative task. Our conscious awareness of our surrounds and an inner awareness exist on a continuum, thus even though one's emphasis is mostly internal in these states, one does not necessarily lose all awareness of the outside world.
