Why does a nucleus always have a positive charge?

pls answer or else I will give you up.

Answers

Answer:

Nucleus has a positive charge as it has protons, which are positively charged inside it.

This is because the nucleus has protons. The atoms do not have a charge because the negative electrons and positive protons cancel eachother out causing the atom to be considered neutral. Hope this helps

Which water feature is often associated with condensation?
Frozen lakes
The ocean
Clouds and fog
Water vapor rising from plants

Answers

I think it is water vapor since condensation is the process of water vapor going back to liquid water.

Clouds and fog are water features often associated with condensation. The correct option is C.

The process by which water vapour, a gaseous form of water, changes into liquid water is called condensation.

When warm, moist air meets a cooler surface or when the air itself cools, it happens. As a result of this cooling, water vapour loses energy and condenses into tiny water droplets or ice crystals, which are what are seen as clouds or fog.

Even though the ocean and frozen lakes are both connected to water, condensation is not a direct result of either of these. As opposed to condensation, water vapour rising from plants is a result of transpiration.

Thus, the correct option is C.

What type of tide is Australia likely to be experiencing in the diagram on the RIGHT and why? In your own words explain what is happening?

Answers

Answer:

Spring tides are extremely high and extremely low. This is created when the sun and moon pull together.

Explanation:

From the diagram, the type of tide Australia is likely to be experiencing is: neap tides.

A tide can be defined as the rise and fall of water level in water bodies such as lakes and oceans, especially due to the gravitational force of attraction exerted by the Moon and Sun on planet Earth.

Generally, there are two (2) main types of a tide and these include:

High tide.Low tide.

Additionally, the two (2) form of a tide are:

I. Spring tide: it occur s twice each month close to the the full and new

moons, especially when the  Moon and Sun pull together.

II. Neap tide: it occurs two times in a month when the Moon is close to its first  and last quarters, especially when the  Moon and Sun pull at a right angle.

From the diagram, the type of tide Australia is likely to be experiencing is neap tides because it happened when the Moon is close to its first  and last quarters and the  Moon and Sun were pulling at a right angle.

Write a short paragraph about electrical current using the terms conductor and insulator.

Answers

In a conductor, electric current can flow freely, in an insulator it cannot. Metals such as copper typify conductors, while most non-metallic solids are said to be good insulators, having extremely high resistance to the flow of charge through them. ... Most atoms hold on to their electrons tightly and are insulators.


I believe that’s what your talking about if not I’m so sorry

Answer:

Bet

Explanation:

In a conductor, electric current can flow freely, in an insulator it cannot. "Conductor" implies that the outer electrons of the atoms are loosely bound and free to move through the material. ... Most atoms hold on to their electrons tightly and are insulators.

when heat is removed from a substance, describe how are the molecules affected

Answers

Answer: look at explanation

Explanation: When heat is removed from a substance, the kinetic energy of the molecules decreases (the molecules start to move more slowly).

The changes are caused by the tendency of the system to reach equilibrium and when the surroundings of the substance have lower kinetic energy, heat is transferred to reach thermodynamic equilibrium.

What's happening in whole is that there is a temperature gradient (difference) between the substance and its surroundings, and for eliminating this gradient, heat flows from the hotter substance to the colder surroundings, for them to have the same temperature.

The temperature of the substance decreases because its molecules have lower kinetic energy.

I just got home after a horrible day. I went to my science class and Mrs. Crowder gave me an F on my test. 1thought I had studied a lot! I know I spent a whole week going overrall of the stuff didn't know. She didn't seem to care whenshe handed it back to me either. Here's the thing I can't tell my mom that I got an F because she thinks I'm supposed to be adoctor and go to college. I'm only in the 8th grade so l've got plenty of time to figure all of that out. But I think the main reason1 got an Fis because I just can't concentrate lately. Mostly it's because of Danielle's presence in my class.I had another argument with Danielle today. I have no idea why she is so focused on making my life miserable. We were reallygood friends in elementary school and had sleepovers all the time. It seems like ever since we went to middle school, she justbecame different. I don't think she's friends with any of us who were together from Kindergarten through s grade. I feel badthat we went our separate ways, but I never thought she would tum against me. Apparently she told the other girls in ourscience class that I'm rich, but not very smart." I'm assuming this is because she saw my dejected face when I got my sciencetest back. We are not rich either. Not that I know of, anyway. I still wear the same jeans, shirts, and shoes that everyone elsedoes. If1 were rich, I'd beg my mom to take me out of this school and put me in a bigger, nicer school somewhere far away on aremote island where Danielle can't bother me. Danielle spends every single day thinking of something negative to say about meand seems to waste a lot of time whispering to her new friends about me. I just wish she would tell me to my face instead of thewhispering. It's so annoying and distracting when I'm trying to pay attention in class. Mrs. Crowder doesn't seem to noticeanything is wrong either. I'm tired of feeling edgy all the time and I've been thinking of ways to defend myselfor get back atDanielle every single day. I will come up with something eventually. Of course, I'm not going to say anything to any of myteachers because then Danielle will win and probably call me a tattlctale.
