Explain an experiment you could run to test the Big Bang theory, including the design and execution, and any observations you can make of the world around you related to the scientific theory. And explain how the observations support of refute the theory!!! Will mark branliest
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.

can someone help me convert these?
Assuming you are supposed to write each conversion in scientific notation:
(2) 1 m = 100 cm, so
(67 cm) × (1/100 m/cm) = 67/100 m = 0.67 m = 6.7 × 10 ⁻¹ m
(3) 1 km = 1,000 m, so
(1.2 km) × (1000 m/km) = 1200 m = 1.2 × 10³ m
(4) 1 m = 1,000 mm = 10³ mm, so
(6.2 × 10 ⁻³ m) × (10³ mm/m) = 6.2 mm
(5) 1 m = 1,000,000,000 nm = 10⁹ nm, so
(4.05 × 10³ nm) × (1/10⁹ m/nm) = 4.05 × 10 ⁻⁶ m
(6) 1 g = 1,000,000 µg = 10⁶ µg, so
(3200 µg) × (1/10⁶ g/µg) = 3200 × 10 ⁻⁶ g = 3.2 × 10 ⁻³ g

Alpha particles have two protons and two neutrons. Therefore, option (D) is correct.
What is an alpha particle?Alpha particles can be defined as positively charged particles released from the decay of several radioactive materials. The mass of the Alpha particle is because of the presence of two protons and two neutrons. Therefore, the Alpha particles nucleus is very similar to the nucleus of the Helium atom and are denoted by the Greek alphabet α.
An alpha particle or ray is also known as doubly ionized helium nuclei (He²⁺). The alpha particle's mass is equal to 6.64 × 10⁻²⁷ Kg. Alpha particles are generally generated during the standard radioactive decay of atomic nuclei.
Alpha particles contains the kinetic energy of 5MeV and a speed of 5 % of that of the speed of light. They are also formed in high-energy particle accelerators and are highly ionized particles with low penetration depth compared to other particles.

PLEASE HELP AM GIVING 20 POINTS A worker in a factory has discovered a material that is confusing. It can be stored in a container but can also flow from one container to another. It forms powder after some time. The worker is confused and does not know which state of matter it belongs. As a student of Physics, prepare a message that will help the worker in the factory to properly classify the substance in the right state of matter.
The factory worker need to know is the state of the material at room temperature and atmospheric pressure.
Matter is anything that has mass and occupy space. Everything around is composed of matter. The material can easily be classified by considering the state of matter in which the material is found at room temperature and atmospheric pressure.
Hence, all the factory worker need to know is the state of the material at room temperature and atmospheric pressure. This will tell us whether it is a liquid, solid or gas.

what is the unit of work ?
Answer:
a joule is the unit of work
Explanation:
What does the term "heat capacity" refer to? Question 2 options: The amount of heat energy needed to raise the temperature of a unit mass of a material one degree A ratio of the amount of heat a material will absorb to the amount of heat it immediately releases The amount of heat that must be applied to a solid to convert it to a liquid The amount of heat that a liquid can absorb until the particles speed up enough to become a gas
Answer:
Heat capacity is the ratio of the amount of heat energy transferred to an object to the resulting increase in its temperature. Molar heat capacity is a measure of the amount of heat necessary to raise the temperature of one mole of a pure substance by one degree K.

A wheelbarrow of mass 20 kg accelerates from rest and reaches speed of 10m/S2 in 5 seconds.its force?
Answer:
[tex]\boxed {\boxed {\sf 40 \ Newtons}}[/tex]
Explanation:
We are asked to find the force of a wheelbarrow. According to Newton's Second Law of Motion, force is the product of mass and acceleration.
[tex]F= \ m \times a[/tex]
1. Calculate AccelerationThe mass of the wheelbarrow is 20 kilograms. We are not given the acceleration, so we must calculate it using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The wheelbarrow starts at rest or 0 meters per second (initial velocity) and accelerates to reach 10 meters per second (final velocity) in 5 seconds (time).
[tex]v_f=[/tex]10 m/s [tex]v_i=[/tex]0 m/s t= 5 sSubstitute these values into the formula.
[tex]a= \frac{ 10 \ m/s-0 \ m/s}{5 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s[/tex]
[tex]a= 2 \ m/s^2[/tex]
2. Calculate ForceNow we know the mass and acceleration of the wheelbarrow
m= 20 kg a= 2 m/s²Substitute the values into the force formula.
[tex]F= 20 \ kg \times 2 \ m/s^2[/tex]
[tex]F= 40 \ kg*m/s^2[/tex]
Convert the units. 1 kilogram meter per square second is equal to 1 Newton, so our answer of 40 kilogram meters per square second is equal to 40 Newtons.
[tex]F= 40 \ N[/tex]
Answer:
40 N
Explanation:
We know that
F = ma
and
a = (v - u)/t
So,
F = m(v - u)/t
F = 20(10 - 0)/5
F = 20(10/5)
F = 20(2)
F = 40 N
a 16 Watt bulb is used for 5 hrs. what is the energy consumed by the bulb
Energy = (power) x (time)
Energy = (16 watt) x (5 hours)
Energy = 80 watt-hours
or
Energy = 0.08 Kilowatt-hours
or
1 watt = 1 joule/second
5 hours = 18,000 seconds
Energy = (16 joule/sec) x (18,000 sec)
Energy = 288,000 Joules
Explanation:
A unit of electricity is represented in kilowatt-hour (KWh). To calculate units, you need to find the energy consumption. It is easy, just multiply power with time.
(16×5 ) watt-hour=80Wh.
Convert it to kilowatt-hour i.e 0.08 KWh/day.
So 0.08 KWh is the energy consumption for one day.

Todas las líneas del terreno de juego deberán se líneas continuas y tener la misma anchura, como máximo 12 cm., menos las líneas de meta que deben tener la misma anchura que los postes y larguero de la portería. Todas las líneas que delimitan al campo forma parte del terreno de juego. El terreno de juego puede ser de tierra, césped natural ó césped artificial de color verde según las normas del reglamento de la competición. El terreno de juego está dividido en dos partes iguales por una línea que unirá los puntos medios de las dos líneas de banda. El centro del campo estará marcado con un punto situado en la mitad de la línea media que divide las dos partes iguales del campo, tomando este punto como centro, haremos circulo de un radio de 9,15 metros. También se puede poner un banderín en cada extremo de la línea de media, a una distancia mínima de 1 m al exterior de la línea de banda.
