Why is 250 million years called a cosmic year?
That’s the amount of time it takes the Milky Way to revolve around the Universe core.
That’s the amount of time it takes the Milky Way to rotate on its axis.
That’s the amount of time it takes the solar system to rotate on its axis.
That’s the amount of time it takes the solar system to revolve around the Milky way core.
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.
What is the Milky way?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.

London lives 1200 meters south of Chick-fil-A and is thinking about going there for lunch. When she is ready to leave, she realizes she left her wallet at her Aunt's house. She walks 750 meters to her aunt's house and then 1000 meters to Chick-fil-A. It took her 30 minutes to get from her house to Chick-fil-A. What was her distance traveled?
Answer:
1750 m
Explanation:
The distance traveled is the 750 meters to the Aunt's house plus the 1000 m from there to Chick-fil-A.
750 +1000 = 1750 . . . meters traveled

Answer:
Image result for what is the force the when does when Gravity pushes you
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.

A box slides down a frictionless incline, gaining speed. The work done by the normal force n is _______.
a.) positive
b.) negative
c.) zero
d.) undefined
Answer:
0
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.
What is normal force?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.
The body is gaining the speed, which means there is a change in kinetic energy.The change in kinetic energy is equal to the work done.The friction force is the product of coefficient of the friction and normal force.The friction force for the given case is zero. Thus, the normal force must be equal to the zero.Thus, the work done by the normal force n when the box slides down a frictionless incline and gaining speed is zero.

When the propeller were turning at 25 rad/s , what is the period (in seconds) of this propeller?
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.
What is Velocity?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.

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
[tex]\frac{155km}{1hour} = \frac{4.25km}{x hours}[/tex]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

A rubber duck of volume 2,500cm3 floats in water with 20% of its volume submerged. You want to hold the duck under water so it is at rest and completely submerged. How much force do you have to apply? If you release the duck, what will be its acceleration at that instant?
The force applied to the submerged rubber duck is 4.9 N.
Density of the rubber duck
The density of the rubber duck is calculated as follows;
ρ = S.G x density of water
ρ = 0.2 x 1000 kg/m³
ρ = 200 kg/m³
Force applied to the duckF = mg = (ρV)g

find the current and voltage across each resistor in the given circuit.
Answer:
R1, R4: 1.3433 VR2: 0 VR3: 6.3134 VExplanation:
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

B. lose all awareness of their surroundings.
C. temporarily suspend their sense of initiative.
D. are in a deep trance, which is similar to stage 3 NREM sleep.
During hypnosis, people temporarily suspend their sense of initiative. Hence, option (C) is correct.
What is hypnosis?
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.
