La cantidad de materia en un objeto.
Scrat [10]

La respuesta correcta es Masa

Explicación:

Todos los objetos existentes en el universo se componen de materia cuya unidad básica es conocida como átomo. A su vez el átomo se compone de subpartículas que incluyen protones, neutrones y electrones. Además de esto, la cantidad de materia o átomos en un objeto o cuerpo, por ejemplo la cantidad de materia en un balón se conoce como masa. Este factor se mide en unidades como gramos o kilos, por ejemplo, la cantidad de masa en una manzana es de aproximadamente de 150 gr. Finalmente, la masa se diferencia del peso porque en el peso la fuerza gravitacional y no solamente la materia se debe considerar.

Suppose that when you ride on your 7.50 kg bike the weight of you and the bike is supported equally by the two tires. If the gau
natali 33 [55]

Answer: 567 N

Explanation:

If the weight of the person and the bike are supported equally by the two tires, this means that the force acting on each tire, is half of the total weight.

We know that the gauge pressure in one tire, by definition, is equal to the force on the tire, over the contact surface between each tire and the road, so we can write:

P= F/A = (mrider g + mbike g) / A = (Fgrider + 7.5 kg. 9.8 m/s2) / 703 mm2 (1)

As the pressure data is given in lb/in2, it is needed to convert to N/mm2, as follows:

65.5 lb/in2 = 0.455 N/mm2.

Replacing in (1), and solving for  Fgrider, we have:

Fgrider = 567 N

Anna35 [415]

Answer:

The correct answer is "53.15 days".

Explanation:

Given that:

Half life of 131_{I},

T_{\frac{1}{2} }= 8 \ days

  • Let the initial activity be "R_o".
  • and, activity to time t be "R".

To find t when R will be "1%" of R_o, then

⇒ R=\frac{1}{100}R_o

As we know,

⇒ R=R_o e^{-\lambda t}

or,

∴ e^{\lambda t}=\frac{R_o}{R}

By putting the values, we get

        =\frac{R_o}{\frac{R}{100} }

        =100

We know that,

Decay constant, \lambda = \frac{ln2}{T_{\frac{1}{2} }}

hence,

⇒ \lambda t=ln100

     t=\frac{ln100}{\lambda}

        =\frac{ln100}{\frac{ln2}{8} }

        =53.15 \ days
