Answer:

Ver explicación

Explanation:

Según los principios de Arquímedes, el empuje hacia arriba de un objeto sumergido en un fluido es igual al peso del fluido desplazado.

Por eso

Empuje hacia arriba = volumen del objeto * densidad del fluido * aceleración debida a la gravedad

Empuje hacia arriba = 2 * 10 ^ -6 / 2 * 1 * 10 ^ 3 * 10

Empuje hacia arriba = 0.01 N

Desde;

Empuje hacia arriba = peso del fluido desplazado

peso del fluido desplazado = 0.01 N

Masa de fluido desplazado = 0.01 N / 10 = 1 * 10 ^ -3 Kg o 1 g

A box is held at rest by two ropes that form 30° angles with the vertical. The tension T in either rope is 42 N. What is the wei
iragen [17]
<h3><u>Answer;</u></h3>

= 73 N

<h3><u>Explanation</u>;</h3>

Using the formula

2 T cos(30°) = w

Where; T is the tension on each string, while w is the weight of the box given by mg

Therefore;

W = 2Tcos 30°

    = 2 × 42 cos 30°

    = 84 cos 30°

    = 72.74

<u>   ≈ 73 N</u>
