Answer:

5.15 when the angle of incidence is equal to critical angle the angle of reflection is equal to 90 if the angle of incidence is bigger than the critical anger the reflected ray will not emerge from the medium but will be reflected back into the medium this is called total internet reflection

Para levantar del suelo una caja metálica de 50 Kg se emplea maquinaria que utiliza un cable inextensible e imprime una acelerac

dimulka [17.4K]

Answer:

T = 530 N , t = 12.65 s

Explanation:

This is an exercise on Newton's second law,

T - W = m a

where T is the tension of the cable, W the weight and the steel of the box

T = W + ma

the weight of a body is

W = m g

Let's replace

T = m g + ma

T = m (g + a)

let's calculate

T = 50 (9.8 + 0.8)

T = 530 N

To calculate the time we use

y = v₀t + ½ a t²

since the box starts from rest on the sole its initial velocity is zero

y = ½ a t2

t = √ 2y / a

let's calculate

t = √ (2 10 / 0.8)

t = 12.65 s

TRASLATE

Este es un ejercicio de la segunda ley de Newton,

T – W = m a

donde T es la tension del cable, W el peso y a la aceracion de la caja

T = W + ma

el pesode un cuerpo es

W = m g

Substituyamos

T = m g + ma

T = m ( g +a)

calculemos

T = 50 ( 9,8 + 0,8)

T = 530 N

Para calcular el tiempo usamos

y = v₀t + ½ a t²

como la caja parte del reposo en el suela su velocidad inicial es cero

y= ½ a t²

t= √ 2y/a

calculemos

t = √ (2 10/0,8)

t = 12,65 s

A dish is given to you, which contains a blackish-yellow powder. When you move a magnet over it, you are amazed to see black par

myrzilka [38]

Answer:

In the case of the blackish-yellow powder, the black color is due to the presence of a iron and yellow color is due to sulfur. As the iron has retained its original properties it has got attached to the magnet. Thus the blackish-yellow powder is considered a mixture.

The resultant of two forces acting on the same point simultaneously will be the greatest when the angle between them is:a) 180 d

r-ruslan [8.4K]

Answer:

0 degrees

Explanation:

Let $F_1\ and\ F_2$ are two forces. The resultant of two forces acting on the same point is given by :

$F_R=\sqrt{F_1^2+F_2^2+2F_1F_2\ cos\theta}$

Where $\theta$ is the angle between two forces

When $\theta=0$ i.e. when two forces are parallel to each other,

$F_R=\sqrt{F_1^2+F_2^2+2F_1F_2\ cos(0)}$

$F_R=\sqrt{F_1^2+F_2^2+2F_1F_2}$

When $\theta=90^{\circ}$ i.e. when two forces are parallel to each other,

$F_R=\sqrt{F_1^2+F_2^2+F_1F_2\ cos(90)}$

$F_R=\sqrt{F_1^2+F_2^2}$

When $\theta=180^{\circ}$ i.e. when two forces are parallel to each other,

$F_R=\sqrt{F_1^2+F_2^2+F_1F_2\ cos(180)}$

$F_R=\sqrt{F_1^2+F_2^2-2F_1F_2}$

It is clear that the resultant of two forces acting on the same point simultaneously will be the greatest when the angle between them is 0 degrees. Hence, this is the required solution.

Car B has the same mass as Car A but is going twice as fast. If the same constant force brings both cars to a stop, how far will

evablogger [386]

Answer:four times

Explanation:

Given

mass of both cars A and B are same suppose m

but velocity of car B is same as of car A

Suppose velocity of car A is u

Velocity of car B is 2 u

A constant force is applied on both the cars such that they come to rest by travelling certain distance
