For each of the following decays or reactions, name at least. one conservation law that prevents it from occurring.(c) p → π⁺ +
Amanda [17]

(c)p→π⁺₊π⁺₊π

Baryon number is +1 on the left side of the equation, 0 on the

right side. Baryon number is not conserved.

<h3>How do you determine whether a baryon number is conserved?</h3>

  • According to the law of conservation of baryon number, the sum of the baryon numbers of all incoming particles equals the sum of the baryon numbers of all particles produced by the reaction. Energy, and so on, are conserved even if the incoming proton has sufficient energy and charge.
<h3>What is Baryon Number</h3>
  • In particle physics, the baryon number denotes which particles are baryons and which particles are not. Each baryon has a baryon number of 1, and each antibaryon has a baryon number of -1. Other non-baryonic particles have a baryon number of 0. Since there are exotic hadrons like pentaquarks and tetraquarks, there is a general definition of baryon number as:
  • B=1/3(n_{q} -n_q^{-} })
  • wheren_{q} represents the number of quarks and nq represents the number of antiquarks.

Which statement about the function of the cell membrane of all organisms is not correct? The cell membrane forms a barrier that
rosijanka [135]

Answer:

The cell membrane is capable of transforming oxygen and glucose into energy for the cell

Explanation:

The cell membrane encapsulates all the organelles of the cell. It provides protection for the organelles of the cell.

It transports nutrients into the cell and toxic materials out of the cell. It also prevents the entry of harmful materials into the cell.

The cell membrane does not perform the function of  transforming oxygen and glucose into energy for the cell.

Why is alternating current more effective at long–distance travel than direct current?
amid [387]
Because we can send high voltage, low current which is more efficient since large amounts of current in the line causes power inefficiencies. AC can be transformed locally to high current lower voltage

Which principle states that sediments are deposited in sequence unless they are disturbed
Volgvan

The manner in which the sediments are being deposited unless the disturbance by tectonic processes makes it non sequential is theorized with the principle of superposition.

<u>Explanation: </u>

The principle of superposition lets us know that the oldest sediment layer is at the bottom with the newer at the top. For example, xenolith in igneous rock must be older than the rock it contains.

The formation of sedimentary rocks is done via sedimentation occurring in the sequential basis. Due to tectonic process or disruption or even say faults, the layers are sediment in non sequential manner. The entire manner of sequential layering gets turn upside down.

How effectiveness of a small force is increased when action area of force is<br> reduced?
STatiana [176]

Answer:

The force is proportional to the area, for if we increase the area but keep the number of molecules per cubic centimeter the same, we increase the number of collisions with the piston in the same proportion as the area was increased.

Explanation:

more area =more space = more free for molecules = less pressure = less force.
