Frequency = 1200 rev/minute

Frequency = (1200 rev/minute) · (1 minute / 60 seconds)

Frequency = (1200 / 60) (rev - minute / minute - seconds)

<em>Frequency = 20 rev/second</em>

daser333 [38]

Answer:

1) as far as I remember

Let's take 20 as vf (final velocity) and 11 as (initial velocity) and 4 as time

So we would use this formula a=vf-vi/t

So 20-11/4

Elis [28]

Answer:

0.25 cm³.

Explanation:

We shall apply Boyle's law to find the solution . According to it

PV = constant where P is pressure and V is volume of the gas.

P₁ V₁ = P₂V₂

1 x .5 = 2 x V₂

V₂ = 0.25 cm³.

El tren Lima la Orolla va a una velocidad de 10 km/h y de pronto aplica el freno por un derrumbe en la via. Si demora 18 segundo
Naya [18.7K]

Answer:

Distancia = 50.04 metros

Explanation:

Dados los siguientes datos;

Velocidad = 10 km/h

Tiempo = 18 segundos

Para encontrar la distancia;

Conversión:

10 km/h = 10 * 1000/3600 = 2.78 m/s

Distancia = velocidad * tiempo

Distancia = 2.78 * 18

Distancia = 50.04 metros

Por lo tanto, el tren viajaría 50.04 metros antes de detenerse por completo.

A β− and a β+ particle meet and interact within a tissue. Discuss what would be the likely outcome of this interaction.
Arturiano [62]

When a β− and a β+ particle meet and interact they are annihilated.

Every matter has an antimatter. An antimatter of a particular particle is another particle that has exactly the same properties as the initial particle but carries an opposite charge.

If we look at β− and β+ particles, we will notice that they are matter and antimatter. The interaction of matter and antimatter leads to annihilation. The energy produced by annihilation of matter and antimatter is enough to destroy the tissue.

So, when β− and a β+ particle meet and interact they are annihilated.
