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.

What happens to acceleration when mass is increased
Answer: acceleration will slow down.
Explanation: Since mass is inversely proportional to acceleration, if you increase the mass at a given force the rate of acceleration slows.
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.

show that vector a + vector b = vector b + vector a.
Recall that vector addition can be visually represented by the head-to-tail method. This means that the head of one vector is glued to the tail of the other vector, to point us directly to the target vector we're after. Think of it like following instructions on a map.
A visual example is shown below. There are two pathways to arrive at the c = a+b vector. The patheway on the right is a+b while the path on the left is b+a. The order doesn't matter since we arrive at the same destination.
-------------------------------------
Here's an algebraic approach without the need of a drawing.
Consider that vectors a and b are defined like so
a = <p,q>
b = <r,s>
where p,q,r,s are real numbers. They define the coordinates of the two vectors.
Adding vectors a and b gets us
a+b = <p,q>+<r,s> = <p+r,q+s>
We add the corresponding coordinates. Since p+r is the same as r+p, we can say,
b+a = <r,s>+<p,q> = <r+p,s+q> = <p+r,s+q> = a+b
Therefore, a+b = b+a. Again, this all relies on the fact that addition of scalar numbers can be done in any order. So by extension, vector addition can be done in any order. This applies to multiple vectors and not just two of them.

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
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.

variable in this experiment?
O A. The time it takes for the water to boil
O B. The amount of salt added to the water
C. The kind of bottles used
D. The brand of salt used
Answer:
A. The time it takes for the water to boil
It is because salt was added into the water. So the responding variable is the time taken to boil the water.
hope this help u. good luck

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.

Kepler's Laws of Motion explain why ________.
Answer:
Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. ... (3) The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.
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
