Answer:

Part A

La tensión en la cadena es de aproximadamente 364,14 Newtons

Part B

La fuerza con la que se empuja el columpio es de aproximadamente 327,874 Newtons

Explanation:

Parte A

Los parámetros dados son;

La masa del asiento en el que se sienta el niño = 15 kg

La inclinación de la cadena de la vertical, θ = 42 °

La masa del niño = 35 kg

La aceleración debida a la gravedad, g = 9,8 m / s²

La tensión en la cuerda, 'T', se da de la siguiente manera;

T = m · g · cos (θ)

Dónde;

m = m₁ + m₂ = 15 kg + 35 kg = 50 kg

g = La aceleración debida a la gravedad = 9,8 m / s²

θ = 42 °

Por lo tanto;

T = 50 kg × 9,8 m / s² × cos (42 °) ≈ 364,14 N

La tensión en la cadena, T ≈ 364.14 N

Parte B

La fuerza con la que se empuja el columpio, 'F', se da de la siguiente manera;

F = m · g · sin (θ)

Por lo tanto;

F ≈ 50 kg × 9,8 m / s² × sen (42 °) ≈ 327,874 N

La fuerza con la que se empuja el columpio, F ≈ 327,874 N.

A 508-g sample of sodium bicarbonate (NaHCO3) contains how many moles of sodium bicarbonate (NaHCO3)?
Blizzard [7]

molar mass = (22.99) + (1.01) + (12.01) + 3(16.00)

molar mass = 84.01 g/mol

//

(508g)(1 mol/84.01 g) = 6.0

There are 6.0 moles of sodium bicarbonate

In the given question according to the information the process of polymerization is an addition polymerization.

<h3>What is polymerization?</h3>

Polymerization is a process in which addition of many small molecules takes place for the formation of a large three dimensional substance known as polymer.

In the polymerization of polyethene the small repeating molecule is ethene and in this process product formed due to the addition process to the double bond of the ethene.

  • In condensation polymerisation removal of water molecule or any other molecule takes place.
  • In dehydrogenation polymerisation removal of hydrogen molecule takes place.
  • In dehydrohalogenation polymerisation removal of hydrogen halide molecule takes place.

Hence given process is an addition polymerisation.
