<h3>Explanation</h3>

Work is defined as a force acting on a body in the direction of a displacement. The unit for displacement is the meter, and the unit for a force is the Newton. Therefore, the unit for work is the Newton-meter or joule.

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>

Formula = solute+solvent=<br>

Alexus [3.1K]

Answer:

solute + solvent = solution

Explanation:

solute is <em>Any substance that is dissolved in a liquid solvent to create a solution</em>

solvent is <em>A liquid that dissolves a solid, liquid, or gaseous solute, resulting in a solution.</em>

and.

solution is <em>A homogeneous mixture, which may be liquid, gas or solid, formed by dissolving one or more substances.</em>

I WILL GIVE BRAINLIST TO CORRECT ANSWERSSSS

sattari [20]

Answer:

The answer is SYMBOL B.

Explanation:

The correct schematic is the one that shows three groups of long and short lines. A schematic with one long and one short (one group) would be a one cell; a schematic with a long, a short, a long, a short (two group), would be a two cell; and a schematic with a long, a short, a long, a short, a long and a short (three group), would be a three cell- hence why the answer is symbol B.

- Un nadador realiza en 10 seg. Un "largo" de ida en una pileta de 25m .El de vuelta lo hace en 12 seg. A) ¿cuál fue el desplaza

viva [34]

Answer:

d = 0m

v_avg = 2.5 m/s

Explanation:

A) The distance traveled by the swimmer was:

$x = 25m+25m=50m$

However, the displacement is zero because the final position of the swimmer is the same as the initial position.

displacement = 0m

The average velocity was:

$v_{avg}=\frac{25m}{10s}=2.5\frac{m}{s}$

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

A) La distancia recorrida por el nadador fue:

Sin embargo, el desplazamiento es cero porque la posición final del nadador es la misma que la posición inicial.

desplazamiento = 0m

La velocidad promedio fue:
