Fórmula de la aceleración
La mecánica clásica entiende la aceleración como una variación de la velocidad de un cuerpo en el tiempo. Matemáticamente esto se escribe como: a = dv / dt, donde a es aceleración, dv la diferencia de velocidades y dt el tiempo en que ocurre la aceleración.

Sloan [31]

Answer:

Constructive interference

Explanation:

Here, the medium is same, same wavelength, same frequency, same amplitude and same direction of propagation.

Let the intensity of waves be I which is same for both

The formula for the net intensity is

$I^{2}=I_{1}^{2}+I_{2}^{2}+2I_{1}I_{2}Cos\phi$

where, Ф be the phase difference

So, $I_{R}^{2}=I^{2}+I^{2}+2IICos6\pi$

Here, IR is maximum so the interference is constructive in nature.

Two blocks are initially at rest with a compressed spring between them. When the spring is released, the 2m block moves to the l

Vlad1618 [11]

<u>Answer:</u>

In an <u>inelastic collision</u> the kinetic energy is not conserved, but <u>the total momentum of the system is conserved</u>.

In other words; the Initial momentum $P_{i}$ is equal to the Final Momentum $P_{f}$ :

$P_{i}=P_{f}$

Then:

This means that after the collision the kinetic energy is transformed (dissipated) into another type of energy (caloric energy, for example); and there may be deformation in the blocks.

Therefore, the sentence that best describes this situation is:

<h2>The total momentum is zero. </h2>

What is the second step of the decision-making process?

Reptile [31]

Answer:

A.Consider and evaluate the consequences of each choice

Explanation:

As you enter the decision-making proccess you would have to see the different options that you have, after this you just have to consider and evaluate the consequences of the different options that you have, in this phase you have to weight the consequences and what it would take to make those decisions.
