Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

Answer:

The value is $v = 3.57 \ m/s$

Explanation:

From the question we are told that

The depth is $d = 979 \ m$

The time taken for water to fall to below the river is $t = 14 \ s$

The horizontal distance from the base of the vertical cliff is $h = 50 \ m$

Generally the horizontal speed at the top is mathematically represented as

$v = \frac{h}{t}$

=> $v = \frac{ 50}{ 14 }$

=> $v = 3.57 \ m/s$

A gymnast is in a tucked position to complete her somersaults. While tucked her moment of inertia about an axis through the cent

torisob [31]

Answer:

$\omega_s=12.8886\ rad.s^{-1}$

Explanation:

Given that:

moment of inertia of tucked body, $I_t=16\ kg.m^2$

rotational speed of the body, $N_t=2.5\ rev.s^{-1}$

i.e. $\omega_t=2\pi\times 2.5=15.708\ rad.s^{-1}$

moment of inertia of the straightened body, $I_s=19.5\ kg.m^2$

<u>Now using the law of conservation of angular momentum:</u>

angular momentum of tucked body=angular momentum of straight body

$I_t.\omega_t=I_s.\omega_s$

$16\times 15.708=19.5\times \omega_s$

$\omega_s=12.8886\ rad.s^{-1}$
