In the Millikan oil drop experiment, when the switch is opened, we determine the charge of the electron.

Explanation:

Millikan's oil drop experiment is designed to measure the charge and terminal velocity of oil droplets.

Initially, without voltage supplied, droplets of oil gather electrons while passing through air, hence acquiring a negative charge.

By varying the voltage across the plates, it becomes possible to suspend the droplets in mid-air. Millikan observed individual droplets, adjusting the voltage and recording the outcomes. Through numerous trials, he established that the charge could only take on specific fixed values.

After repeated experiments, he arrived at the conclusion that the charge of an electron is 1.602176487 ×10−19 C.

Determine whether each substance will sink or float in corn syrup, which has a density of 1.36 g/cm3. Write “sink” or “float” in

Sav [2226]

Explanation:

A substance will float if it has a lower density than the liquid it is placed in.
A substance will sink if its density exceeds that of the liquid.

Density of corn syrup = $1.36 g/cm^3$

1) Density of gasoline = $0.748 g/cm^3$

Gasoline's density is less than that of corn syrup, indicating it will float in corn syrup.

2) Density of water = $1 g/cm^3$

Water's density is also less than that of corn syrup, meaning it will float in corn syrup.

3) Density of honey = $1.45 g/cm^3$

Honey's density exceeds that of corn syrup, so it will sink in corn syrup.

4) Density of titanium = $4.506 g/cm^3$

The density of titanium is greater than that of corn syrup, hence it will sink in corn syrup.

Esta pregunta está incompleta, la pregunta completa es;

La figura muestra un recipiente sellado en la parte superior por un pistón móvil. Dentro del recipiente hay un gas ideal a 1.00 atm. 20.0°C y 1.00 L.

"¿Cuál será la presión dentro del recipiente si el pistón se mueve hasta la marca de 1.60 L mientras se mantiene constante la temperatura del gas?"

Answer:

la presión dentro del recipiente será 0.625 atm si el pistón se mueve hasta la marca de 1.60 L manteniendo constante la temperatura del gas

Explicación:

Dado que;

P₁ = 1.00 atm

P₂ =?

V₁ = 1 L

V₂ = 1.60 L

la temperatura del gas se mantiene constante

sabemos que;

P₁V₁ = P₂V₂

por lo que hacemos la sustitución

1 × 1 = P₂ × 1.60

P₂ = 1 / 1.60

P₂ = 0.625 atm

Por lo tanto, la presión dentro del recipiente será 0.625 atm si el pistón se mueve hasta la marca de 1.60 L mientras la temperatura del gas se mantiene constante
