Hi, your answer is below.
Time dilation is usually defined as the slowing of the passage of time experienced by objects in motion relative to an observer; measurable only a relativistic speeds. Because time moves at various rates for the two of them depending on their relative velocities and/or proximity to things of considerable mass, if two persons (or objects) are moving relative to one another, they will age at separate rates. They will age differently from one another over time since their two timepieces will really tick at separate speeds. If they cross paths again later, they will both have aged differently, which may be determined by using their own timepieces, presuming they each had one. Einstein's Special and General Relativity equations, which have undergone extensive testing over the past 115 years and have never been shown to falter, regulate this "time dilation." The general relativity theory of Einstein, which states that a huge body's gravity warps space-time around it, causes time to move more quickly or more slowly depending on how far away the mass is from the observer, is what causes this so-called "time-dilation" phenomenon.
Thank you,

If a giant molecular cloud is 59 pc in diameter and a shock wave sweeps through at 18 km/s, how long will it take the shock wave (in years) to sweep through the cloud?
The time it will take for the shock wave in years to sweep through the cloud is 3.2075 x 10⁷ years.
What is Velocity?Velocity is the directional speed of a moving object as an indicator of its rate of change in location as perceived from a certain frame of reference and measured by a specific time standard.
As it is known that one parsec is equal to 3.086×10¹⁶ meters. Therefore, the diameter of the molecular cloud is,
Diameter of the molecule = 59 pc
= 59 × 3.086×10¹⁶ meters
= 1.82074 × 10¹⁸ meters
= 1.82074 × 10¹⁵ kilometres
Given that the shock wave sweeps through at 18 km/s. And as it is known that velocity is the ratio of distance and time. Therefore, the time it will take for the shock wave to sweep through the molecule cloud is,
Velocity = Distance / Time
18 km/s = 1.82074 × 10¹⁵ km / Time
Time = 1.82074 × 10¹⁵ km / 18 km/s
t = 1.01152x10¹⁴ seconds
Since one year is equal to 31,536,000 seconds, therefore, the time in years is equal to,
t = 1.01152x10¹⁵ seconds / 31,536,000 seconds per year
t = 32,075,088.79 years
t = 3.2075 x 10⁷ years
Hence, the time it will take for the shock wave in years to sweep through the cloud is 3.2075 x 10⁷ years.

What is the tension in the string if the turntable is held fixed, with the mass hanging from the pulley (i. e. , the mass is stationary)?
Weight of the mass is the tension in the string if the turntable is held fixed, with the mass hanging from the pulley
Weight is a force that acts at all times on all objects near Earth. The Earth pulls on all objects with a force of gravity downward toward the center of the Earth. Weight (symbolized w ) is a quantity representing the force exerted on a particle or object by an acceleration field, particularly the gravitational field of the Earth at the surface.
The tension force is defined as the force that is transmitted through a rope, string or wire when pulled by forces acting from opposite sides. The tension force is directed over the length of the wire and pulls energy equally on the bodies at the ends.
The direction of tension is the pull which is given the name tension. Thus, the tension will point away from the mass in the direction of the string/rope. In case of the hanging mass, the string pulls it upwards, so the string/rope exerts an upper force on the mass and the tension will be in the upper side.
Tension will act opposite the the weight of the mass attached in order to maintain equilibrium .

The wrong statement is that sound waves created vibration Option A.
What are sound waves?Sound is a type of waves that moves in compressions and rare factions. This implies that sound is a mechanical wave. Recall that a mechanical wave is one that requires a material medium for propagation. Now we know that if we set the medium into vibration, that is when the sound waves begins to vibrate. That brings us to the idea that it is the vibration that causes the sound waves and not the sound waves that creates the vibration.

Ice cubes float in a glass of iced tea. why would cooling be less if the cubes were instead on the bottom of teh drink?
Ice cubes float in a glass of iced tea because due to a lack of convection, ice cubes will cool more slowly if they are on the bottom. Ice is denser than water at 4° C.
Heat is transferred through convection, which is the large-scale movement of molecules inside gases and liquids. Conduction is used to move heat from the object to the fluid initially, but the fluid motion is responsible for the bulk of the heat transfer.
Natural convection is caused by the fact that most fluids have a tendency to expand when heated, which causes them to become less dense and rise due to the increased buoyancy. Heat is transferred between two bodies by currents of moving gas or fluid, which is known as convection. In free convection, air or water rises and is replaced by a cooler parcel of air or water as it moves away from the hot body.

A car traveling at a speed of 30. 0 m/s encounters an emergency and comes to a complete stop. how much time will it take for the car to stop if it decelerates at -4. 0 m/s^2?
With the help of the motion equation, it is calculated that if the vehicle slows down at a pace of -4.0 m/s², stopping will take 7.5 seconds.
Motion equation:
Three motion equations commonly referred to as the rules of constant acceleration, exist for a uniform acceleration. In order to derive the components such as displacement(s), velocity(initial =u and final = v), time(t), and acceleration(a), these equations are utilized. They are therefore only applicable in straight-line motion with constant acceleration. Here are the three equations:
v=u+at or, v = u-atv²=u²+2as s= ut+1/2 at²Calculating the time :
The formula for the motion equation is
v = u - at
v = final velocity
u = initial velocity
a = acceleration
t = time
Here, v = 0 ,as the automobile comes to a stop
u = 30 m/s
a = -4 m/s²
So, v = u - at
⇒0 = 30 - 4t
⇒4t = 30
⇒t = 30/4
⇒t = 7.5 seconds
Therefore, the required time calculated is 7.5 seconds.

The frequency of the re-emitted light is identical to that of the absorbed light.
To find the answer, we need to know more about the frequency of light.
Why the re-emitted light has the same frequency?The wavelength of the light that is momentarily absorbed in glass and then re-emitted is the same, which explains why the re-emitted light has the same frequency as the absorbed light and the frequency of the absorbed light is the same. An electromagnetic wave's energy is inversely related to its frequency.

The appearance of an object as it gets hotter is that the object gets bluer. Hence, option (d) is correct.
What is Wavelength?Wavelength is the separation between the equivalent points of two successive waves. When two points or particles are referred to be "corresponding points," it means that they are both in the same phase and have completed exactly the same portions of their vibration. Typically, the wavelength of transverse waves—those whose points advance at right angles to one another—is assessed from crest to crest or from groove to trough; for longitudinal waves—those whose points advance in the same direction—the wavelength is measured from compression to compaction or from rarefaction to rarefaction.
A wave train's speed (v) in a medium is equal to its frequency (f), hence the formula for wavelength is v/f. Wavelength is commonly represented by the Greek character lambda λ.

An object travels 12 m in the 1st second of travel, 12 m again during the 2nd second of travel, and 12 m again during the 3rd second. Its acceleration is therefore ___ m/s2.
0 m/s^2.
An object travels 12 m in the 1st second of travel, 12 m again during the 2nd second of travel, and 12 m again during the 3rd second. Its acceleration is therefore 0 m/s2.
Given
In First second object travels 12 m
in second second it travels 12 m
In 3rd second it travels 12 m
After observation, the object travels the same distance in the same amount of time, indicating constant velocity motion in a straight line with no acceleration.
Therefore acceleration = 0 m/s^2
What is acceleration?Rate of change of velocity with time, both in terms of speed and direction is known as acceleration. A point or object going straight ahead is accelerated when it accelerates or decelerates.To learn more about acceleration visit:

The obsessive disinhibition form of a craving is the result of dysfunction in the ___________ neurotransmitter.
a. gaba
b. 5ht
c. da
d. op
The obsessive disinhibition form of a craving is the result of dysfunction in the 5ht neurotransmitter.
5HT neurotransmitter:One of the major neurotransmitters in mammals' nervous systems is 5-HT (also known as serotonin), which is well known for modulating key aspects of daily living like mood, sleep, social behaviors, learning, and appetite (Barnes and Sharp, 1999; Gingrich and Hen, 2001; Canli and Lesch, 2007).
The central and peripheral nervous systems contain a variety of G protein-coupled receptors and ligand-gated ion channels known as 5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors. Both excitatory and inhibitory neurotransmission is mediated by them.
5-HT produces only inhibitory effects on excitatory or inhibitory transmission in the bed nucleus of the stria terminalis (BNST) [16] and the periaqueductal grey (PAG).
