Answer: Option C

Explanation:

To find the position of the image when an object lies in front of lens, usually three rays are used. One incident ray passes through the focus and would be parallel to the axis after refraction from the lens. Second would just pass through the optical center. Third incident ray would be parallel to the axis and would refract from the lens and pass through the focus on the right hand side.  The three rays would be extended in both the directions and we would see where the three rays would intersect. That would be the position of the image.

Thus, the correct option is C.

Un recipiente contiene 224 dm3 de Ozono de masa 4.561 Kg a 51.09 grados celsius. Calcula la presión del Ozono
kari74 [83]

Answer:

Por lo tanto, la presión del ozono es:

P=0.011\: atm  

Explanation:

Podemos usar la ecuacion de los gases ideales;

PV=nRT (1)

Tenemos:

El volumen V = 224 dm³ = 224 L

La temperatura T = 51.09 C = 324.09 K

La masa es m = 4.561 kg

Lo necesitamos ahora es calvular n que es el numero de moles;

recordemos que el peso molecular del ozono M = 48 g/mol.

n=\frac{m}{M}=\frac{4.561}{48}=0.095\: mol

Finalmente, usando la ecuacion 1 despejamos la presion P

P=\frac{nRT}{V}

P=\frac{0.095*0.082*324.09}{224}  

Por lo tanto, la presion del ozono es:

P=0.011\: atm

A roller coaster, traveling with an initial speed of 21 m/s, decelerates uniformly at -3.5
liberstina [14]

Answer:

S = Vo t + 1/2 a t^2       distance traveled

t = (V2 - V1) / a = (0 - 21) / -3.5 = 6 sec       time to stop

S = 21 * 6 - 3.5 * 6^2 / 2 = 63 m        distance traveled

Two pieces of evidence for plate tectonics?
Reika [66]
Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species.
