If the p-side has a higher doping concentration, explain how to keep tuning to the same radio channel?
zzz [600]

Answer:

increase in temperature of the intrinsic semiconductor

Explanation:

  • If the p-side has a higher doping concentration, it implies that number of holes (positive ion) increased which is greater than number of electron (negative ion) in the n-side
  • in order to balance the intrinsic concentration, that is to balance the number of holes and electrons which depends on temperature.
  • an increase in the temperature of the intrinsic semiconductor (p-side), increases the number of electron but number of holes remains constant.

A balance in the intrinsic concentration helps in tuning to the same radio channel.

Why is the net charge of a neutral atom zero?
nikitadnepr [17]

Answer:

Explanation:

The positive (protons) and negative (electrons) charges balance each other in a neutral atom, which has a net zero charge. Because protons and neutrons each have a mass of 1, the mass of an atom is equal to the number of protons and neutrons of that atom.

A student has a sample of 1.33 moles of fluorine gas that is contained in a 23.3 L container at 314 K. What is the pressure of t
Gelneren [198K]

1.4715 atm is the pressure of the sample 1.33 moles of fluorine gas that is contained in a 23.3 L container at 314 K.

What is an ideal equation?

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas. The terms are: p = pressure, in pascals (Pa).

Given data:

Volume (V) = 23.3 L

Number of mole (n) = 1.33 moles

Temperature (T) = 314 K

Gas constant (R) = 0.821 atm.L/Kmol

Pressure (P) =?

The pressure inside the container can be obtained by using the ideal gas equation as illustrated below:

PV = nRT

P × 23.3 L = 1.33 moles × 0.0821 ×314 K

P = 1.4715 atm

Therefore, the pressure of the sample is 1.4715 atm.

Evaluate three communication skills that can assist you in sustaining positive relationships​
Tpy6a [65]

1. Accept and celebrate differences. One of the biggest challenges we experience in relationships is that we are all different. We can perceive the world in many ways. Certainly astumbling block that we come across when we try to build relationships is a desire or an expectation that people will think like we do and, in this way, it is so much easier to create a rapport. We feel more comfortable when we feel that people “get” us and can see our point of view. Life, however, would be very dull if we were all the same and, while we may find it initially easier, the novelty of sameness soon would wear off. So accepting and celebrating that we are all different is a great starting point.

2. Listen effectively. Listening is a crucial skill in boosting another person’s self-esteem, the silent form of flattery that makes people feel supported and valued. Listening and understanding what others communicate to us is the most important part of successful interaction and vice versa.

Active or reflective listening is the single most useful and important listening skill. In active listening, we also are genuinely interested in understanding what the other person is thinking, feeling, wanting, or what the message means, and we are active in checking out our understanding before we respond with our own new message. We restate or paraphrase our understanding of their message and reflect it back to the sender for verification. This verification or feedback process is what distinguishes active listening and makes it effective.

3. Give people your time. Giving time to people is also a huge gift. In a world where time is of the essence and we are trying to fit in more than one lifetime, we don’t always have the time to give to our loved ones, friends, and work colleagues. Technology has somewhat eroded our ability to build real rapport and we attempt to multi-task by texting and talking at the same time.

Being present in the time you give to people is also important, so that, when you are with someone, you are truly with someone and not dwelling in the past or worrying about the future. The connection we make with other people is the verytouchstone of our existence, and devoting time, energy, and effort to developing and building relationships is one of the most valuable life skills.
