Answer:

Red line is reflected ray.

Explanation:

According to the given figure, the blue line represent the incident ray. It strikes the surface and reflection occurs. The dotted line shows normal.

After reflecting the surface, the ray of light is reflected. Red line shows the reflected light.

In this case, the laws of reflection follows i.e. the angle of incidence is equal to the angle of reflection.

A 5.18x10^4 kg railroad car moves on a frictionless horizontal rails until it hits a horizontal spring stopper with a force cons

nalin [4]

Answer:

The initial velocity of the cart was 0.91m/s.

Explanation:

When the car comes to a stop it has delivered all of its kinetic energy to the spring; therefore,

$\dfrac{1}{2}kx^2 = \dfrac{1}{2} mv^2$

solving for $v$ we get:

$v = x\sqrt{\dfrac{k}{m} },\\$

we put in $k = 4.21*10^{5}N/m$ , $m = 5.18*10^{4}kg$ , and $x = 0.32m$ to get:

$v = (0.32m)\sqrt{\dfrac{4.21*10^5}{5.18*10^4} },\\$

$\boxed{v = 0.91m/s.}$

9. Una jeringa contiene cloro gaseoso, que ocupa un volumen de 95 mL a una presión de 0,96 atm. ¿Qué presión debemos ejercer en

masha68 [24]

Answer:

2.61 atm

Ley de Boyle

Explanation:

$P_1$ = Presión inicial = 0.96 atm

$P_2$ = Presión final

$V_1$ = Volumen inicial = 95 mL

$V_2$ = Volumen final = 35 mL

En este problema usaremos la ley de Boyle.

$\dfrac{P_1}{P_2}=\dfrac{V_2}{V_1}\\\Rightarrow P_2=\dfrac{P_1V_1}{V_2}\\\Rightarrow P_2=\dfrac{0.96\times 95}{35}\\\Rightarrow P_1=2.61\ \text{atm}$

La presión ejercida sobre el émbolo para reducir su volumen es de 2.61 atm.
