The  big bang theory or great expansion explains the formation of the universe from a point with very high density where matter and space were created, it can be observed in an experiment

The Big Bang theory that can be adapted with some home experiments, specifically the expansion can be measured using an experiment with inflating balloons.

Materials

deflated balloons

marker

thread

measuring tape

Description of the experiment

The stars or galaxies are marked repeatedly with an initial separation and this distance is measured by a thread the length and the thread with a meter, this is used as measured by the fact that the surface is curved.

The balloon is inflated and measurements of the separation are made, observing that as the volume of the balloon increases (time increase) the separation of the galaxies increases

The increase in distance is explained by the Big Bang theory or great expansion.

There is also astronomical evidence:

* The redshift of the hydrogen spectral lines that is explained by the Dopler effect, which is a move away from objects

* Background radiation in the microwave range that comes from everywhere and would be the residue of a large initial explosion.

Weightlessness is simply a sensation experienced by an individual when there are no external objects touching one's body and exerting a push or pull upon it.

Answer:

Weightlessness is simply a sensation experienced by an individual when there are no external objects touching one's body and exerting a push or pull upon it. ... When in free fall, the only force acting upon your body is the force of gravity - a non-contact force.

Answer:

Pressure is inversely proportional to Area ...

P = F/A

Answer:

Hence, pressure is inversely proportional to the area of contact. Additional information: In the SI unit system, the unit of force is Newton and the unit of area is square-meter. Atmospheric pressure can be defined as the pressure given by the atmosphere of earth near the surface or at sea level.

Answer:

Yes

Explanation:

[tex]v = \frac{ds}{dt} \\ where \: we \: need \: to \: know \\ \: change \: in \: displacement \\ \: and \: the \: time \: taken[/tex]

if you know the time it took an object to travel between two points and the position of the object at the points, then we can determine the object's instantaneous velocity by using the differential rate of the displacement function with respect to the time.

Instantaneous velocity =  [tex]\frac{dS}{dt}[/tex]

The total displacement covered by any object per unit of time is known as velocity. It depends on the magnitude as well as the direction of the moving object.

velocity= displacement  / time taken

for instantaneous velocity =  [tex]\frac{dS}{dt}[/tex]

Thus, If you know how long it took an item to go between two places and where it was when it got there, you can use the differential rate of the displacement function with respect to time to calculate the object's instantaneous velocity.

Explanation:

The correct definition is distance / time, although teachers like to mix you up sometimes. A question like "How many minutes per mile does it take to go 3miles in 20 minutes?" In this question, the units are upside down.

The standard answer is what is the rate of speed when when 3 miles are covered in 2 hours.

Here the answer is 3/2 = 1.5 miles / hour which is the standard way of writing speed or rate. distance / time.

Answer:

It is b

Explanation:

The question tells you that the distance was increased 3 times the original distance, which means it was moved 3 times

Explanation:

2 h = 120 min

v = 0.1 km/m

distance = v × t

= .1 × 120

= 12 km

Answer:

W = F × d

W = 1 × 1

W = 1 Joule

step by step explanation

An apple is having a force of 1 N and it travels to a distance of 1 m then the work done on the apple by the force of gravity will be equal to 1 J.

Work is a physics term used to describe the transfer of energy that occurs when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation. The element of the strong acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.

Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the pressure is applied at an angle with regard to displacement.

As per the given information in the question,

Force, f = 1 N

Distance, d = 1 m

Then, the work done will be,

W = fd

W = 1 × 1

W = 1 J.
