Here,

Using Formula;

v = u + at

or, 7 = 0 + (6.6*t)

or, 7 = 6.6t

or 7/6.6 = t

or, t = 1.06s

Explanation:

A practical machine is a simple machine that losses energy and have parts that have weights, friction and it causes some loss of work done.

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:

pressure is force per unit length

Answer:

SI unit of displacement is meter

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.

Answer:

As we know 1 liter=1000ml

2 liter bottle of soda has 2000 milliliter in it.

Answer: The acceleration due to gravity increases the velocity of a falling object by 9.8 m/s per

second. Answer B is wrong because velocity increases. Answer C is wrong because the

distance increases every second. Ans. E is wrong because the derivative of distance with

respect to time gives the velocity, not the acceleration.

Explanation:

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:

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.

The answer is C. anti social

Explanation:

Hope that helps!

Answer:

a hypothesis is an assumption made before any research has been completed for the sake of testing (basically what you think is going to happen). A theory is an explanation for what has been shown many times. (what happened with evidence)

Explanation:

Answer:

Given, kelvin temperature = 300 K

C = K – 273.15

C = 300 – 273.15

C = 26.85

Therefore, 300 Kelvin is equal to a celsius temperature of 26.85 °C

Answer:

it must be based on information that other scientists have also gathered

Answer:

hope its ok

Explanation:

Science is a way of learning about what is in the natural world, how the natural world works, and how the natural world got to be the way it is. It is not simply a collection of facts; rather it is a path to understanding.so it should contain a logical theory but it can also never be said as the final answer.

so A) OR D) both are correct

Answer:

80m/s

Explanation:

The formula for velocity is [ v = s/t ] where s = displacement and t = time.

= 400/5

= 80m/s
