Which nucleus completes the following equation?

Physics
2 answers:
IgorLugansk [536]3 years ago

Answer: ^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr

The chromium nucleus will complete the reaction.

Explanation:

The given reaction is a type of radioactive nuclei decay:

Positron emission: It is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. This is also known as \beta ^+-decay. In this the mass number remains same.

_A^Z\textrm{X}\rightarrow _{Z-1}^A\textrm{Y}+_{+1}^0e

Now according to the given reaction:

^{50}_{25}Mn\rightarrow ^{0}_1e+ ^{50}_{24}Cr

The chromium nucleus will complete the reaction.

Deffense [45]

Answer:

The definition of that same given problem is outlined in the following section on the clarification.

Explanation:

The Q seems to be endless (hardly any R on the circuit). So energy equations to describe and forth through the inducer as well as the condenser.  

Presently take a gander at the energy stored in your condensers while charging is Q.

⇒  U =\frac{Qmax^2}{C}

So conclude C doesn't change substantially as well as,

When,

⇒  Q=\frac{Qmax}{2}

⇒  Q^2=\frac{Qmax^2}{4}

And therefore only half of the population power generation remains in the condenser that tends to leave this same inductor energy at 3/4 U.

Some scientists speculate that our universe is not the only universe that exists, but the only one we can gather evidence about.
o-na [289]

This idea is called the multiverse theory

<h3>What is the Multiverse theory?</h3>

According to multiverse hypothesis, our universe, which spans tens of billions of light-years and contains hundreds of billions of galaxies and almost innumerable stars, may not be the only one. Instead, there may be a whole distinct world, far away from ours, and then another, and another. In fact, there may be an infinite number of universes, each with its own set of physical laws, stars and galaxies (if they can exist in those worlds), and perhaps even sentient civilizations.

The idea of the multiverse appears in a few branches of physics (and philosophy), but inflation theory provides the best-known example. According to inflation theory, a hypothetical occurrence took place when our universe was really young—less than a second old. According to NASA, the cosmos had a brief period of fast expansion before "inflating" to become several orders of magnitude larger than it had been.

According to Heling Deng, a cosmologist at Arizona State University and an authority on the multiverse hypothesis, the expansion of our universe is assumed to have stopped some 14 billion years ago. However, Deng noted in an email to Live Science, "inflation does not disappear everywhere at the same time." It's possible that if inflation slows down in one area, it picks up in another.

The current flowing into the branches, or branch current, is divided according to the resistance in the branch that it is going into. Loop current remains the same.

What is the energy of a photon with a frequency of 3. 6 Ă— 1015 Hz? Planck’s constant is 6. 63 Ă— 10â€""34 J•s. 1. 8 Ă— 10â€
erastovalidia [21]

Every photon has some energy within it and that energy is called photon energy.

The energy of photon is 2.38\times10^{-18}\;\rm J.

Given that, frequency of the photon is 3.6\times10^{15}\;\rm Hz and Planck's constant is 6.626\times {{10}^{-34}}.

So the energy of the photon can be calculated by the given formula.

E=h\nu

Where h is plank's constant and \nu is the frequency of the photon.

By substituting the values in the above formula, the photon energy is,

E=6.626\times10^{-34}\times3.6\times10^{15}\;\rm J

E=2.38\times10^{-18}\;\rm J

The energy of photon is 2.38\times10^{-18}\;\rm J.

For more details about the energy of photon, follow the link given below.

Emily holds a banana of mass m over the edge of a bridge of height h. She drops the banana and it falls to the river below. Use
Mariana [72]

Answer:

The mass of the banana is m and it is at height h.

Applying the Law of Conservation of Energy

              Total Energy before fall = Total Energy after fall

                                E_{i}  = E_{f}

Here, total energy is the sum of kinetic energy and potential energy

K.E_{i} + P.E_{i} = K.E_{f} + P.E_{f}       (a)

When banana is at height h, it has

                 K.E_{i} = 0    and    P.E_{i} = mgh          

and when it reaches the river, it has

       K.E_{f}  = 1/2mv^{2}    and   P.E_{f}  = 0

Putting the values in equation (a)

                              0 + mgh = 1/2mv^{2} + 0

                                      mgh = 1/2mv^{2}

<em>cutting 'm' from both sides</em>

<em>                                           </em>gh = 1/2v^{2}

                                          v = \sqrt{2gh}

Hence, the velocity of banana before hitting the water is

                                          v = \sqrt{2gh}
