What is F = m x a in Newton's laws of motion?

Answer:

As we know 1 liter=1000ml

2 liter bottle of soda has 2000 milliliter in it.

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.

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]

The 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).

Substitute 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]

Now we know the mass and acceleration of the wheelbarrow

Substitute 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

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.

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

Answer:

Yes, when dealing with electricity as long as there is an input source there is always built up energy waiting to be used also known as kinetic energy. The fan is not spinning but if it were turned on it would spin instantaneously.

Las dos líneas más largas del terreno de juego se denominarán líneas de banda. Las dos más cortas se llamarán líneas de meta. El terreno de juego será rectangular y la longitud de las líneas de banda deberá ser mayor que las de las líneas de meta. La longitud de la línea de banda debe tener como mínimo 90 metros y como máximo 120 metros. La anchura de la línea de meta debe de tener como mínimo 45 metros y como máximo de 90 metros. 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.

Answer:

two protons and two neutrons

it's the answer. hope it helps

Alpha particles have two protons and two neutrons. Therefore, option (D) is correct.

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.

B. Psycology

Psycology is considered a social science while all the other choices are natural sciences.

Psychology is not considered a natural science. While it deals with the study of the human mind and behavior, psychology is generally classified as a social science rather than a natural science.

Natural science is a branch of science that deals with the study of the natural world, including the physical, chemical, and biological aspects of nature. It is a systematic and empirical approach to understanding the natural phenomena that occur in the universe. Natural sciences include subjects such as physics, chemistry, biology, geology, and astronomy, among others.

These sciences use the scientific method to investigate and explain the behavior of the natural world, relying on observation, experimentation, and analysis of data to formulate theories and laws that can explain natural phenomena. Natural science plays a critical role in our understanding of the universe and has contributed immensely to technological advancements in various fields. Therefore, option (B) is correct.
