A diver comes off a board with arms straight up and legs straight down, giving her a moment of inertia about her rotation axis o

mihalych1998 [28]

Answer:

θ₁ = 0.5 revolution

Explanation:

We will use the conservation of angular momentum as follows:

$L_1=L_2\\I_1\omega_1=I_2\omega_2$

where,

I₁ = initial moment of inertia = 18 kg.m²

I₂ = Final moment of inertia = 3.6 kg.m²

ω₁ = initial angular velocity = ?

ω₂ = Final Angular velocity = $\frac{\theta_2}{t_2} = \frac{2\ rev}{1.2\ s}$ = 1.67 rev/s

Therefore,

$(18\ kg.m^2)\omega_1 = (3.6\ kg.m^2)(1.67\ rev/s)\\\\\omega_1 = \frac{(3.6\ kg.m^2)(1.67\ rev/s)}{(18\ kg.m^2)}\\\\\omega_1 = \frac{\theta_1}{t_1} = 0.333\ rev/s\\\\\theta_1 = (0.333\ rev/s)t_1$

where,

θ₁ = revolutions if she had not tucked at all = ?

t₁ = time = 1.5 s

Therefore,

$\theta_1 = (0.333\ rev/s)(1.5\ s)\\$

<u>θ₁ = 0.5 revolution</u>

How much time does it take light to travel from the moon to the earth, a distance of 384000 km?

Natali5045456 [20]

Answer:

1.28second

Explanation:

The speed of light is constant everywhere, it is

299,792,458m/s=299,792.458km/s

Therefore it takes

$\frac{384000}{299792458} = 1.28sec$

(I) A car slows down from 28 m????s to rest in a distance of 88 m. What was its acceleration, assumed constant?

Nataly [62]

Answer:

The value is $a = - 4.45 m/s^2$

Explanation:

From the question we are told that

The initial speed is $u = 28 \ m/s$ at a distance of $s_1 = 0 \ m$

The final speed is $v = 0 \ m/s$ at a distance of $s_2 = 88 \ m$

Generally from the kinematic equation we have that

$v^2 = u^2 +2as$

=> $a = \frac{v^2 - u^2 }{ 2(s_2 - s_1 )}$

=> $a = \frac{0 - 28^2 }{ 2(88 - 0 )}$

=> $a = - 4.45 m/s^2$

The negative sign shows that it is decelerating

Factors that affect the light intensity received from a source

Roman55 [17]

Light intensity and distance is interrelated. When the distance changes, the intensity of light changes. This relationship is called inverse-square relationship. The inverse-square relationship refers to the fact that when distance changes, light intensity also changes: inverse because when distance decreases, light density increases and when distance increases, the latter decreases; square refers to the fact that light intensity and distance is not a one-to-one relationship.
