Introduces una masa de 80g en una probeta con 60cm cúbicos de agua y el nivel sube hasta 75cm cúbicos. qué densidad tiene la mas
ExtremeBDS [4]

Answer:

d=5.33\ gr/cm^3

Explanation:

<u>Densidad</u>

La densidad de una masa m que ocupa un volumen v se define como:

\displaystyle d=\frac{m}{V}

Tenemos que una masa de 80 gr hace que un volumen de agua se desplace desde 60 cm3 hasta 75 cm3, es decir, el volumen propio de la masa es m = 75 - 60 = 15 cm3.

Con esta información se calcula la densidad:

\displaystyle d=\frac{80\ gr}{15\ cm^3}

Operando:

\boxed{d=5.33\ gr/cm^3}

You throw a 20-n rock vertically into the air from ground level. you observe that when it is a height 15.4 m above the ground, i
gayaneshka [121]

I believe there are two things which we asked to find here:

1. its speed just as it left the ground

2. find its maximum height

 

Solutions:

1. We use the formula:

ΔKE = - ΔPE

where KE is kinetic energy = ½ mv^2, and PE is potential energy = m g h, Δ = change

Therefore:

½ m (v2^2 – v1^2) = m g (h1 – h2)

at initial point, point 1: h1 = 0, v1 = ?

at final point, point 2: h2 = 15.4 m, v2 = 24.2 m/s

½ (24.2^2 – v1^2) = 9.8 (0 – 15.4)

585.64 – v1^2 = -301.84

-v1^2 = 887.48

v1 = 29.8 m/s

So the rock was travelling at 29.8 m/s as it left the ground.

 

2. The maximum height (hmax) reached is calculated using the formula:

v1^2 = 2 g hmax

Rewriting in terms of hmax:

hmax = v1^2 / 2 g

hmax = (29.8)^2 / (2 * 9.8)

hmax = 45.3 m

Therefore the rock reached a maximum height of 45.3 meters.

When dissolved in water, a strong acid
Leviafan [203]

Answer:

A strong acid IONIZES COMPLETELY when dissolved in water.

Explanation:

An acid is said to be a strong acid when on dissolving in water is completely ionized into its proton and conjugate base.

The strength of an acid is determined by the ease in which an acid releases it's proton. Strong acids produces weak conjugate bases and are useful in accelerating some certain chemical reactions and causes chemical burns when exposed to it.
